The Third Beta of Android 16

Posted by Matthew McCullough – VP of Product Management, Android Developer

Android 16 has officially reached Platform Stability today with Beta 3! That means the API surface is locked, the app-facing behaviors are final, and you can push your Android 16-targeted apps to the Play store right now. Read on for coverage of new security and accessibility features in Beta 3.

Android delivers enhancements and new features year-round, and your feedback on the Android beta program plays a key role in helping Android continuously improve. The Android 16 developer site has more information about the beta, including how to get it onto devices and the release timeline. We’re looking forward to hearing what you think, and thank you in advance for your continued help in making Android a platform that benefits everyone.

New in Android 16 Beta 3

At this late stage in the development cycle, there are only a few new things in the Android 16 Beta 3 release for you to consider when developing your apps.

Android 16 timeline showing we are on time with Beta releases ending in March

Broadcast audio support

Pixel 9 devices on Android 16 Beta now support Auracast broadcast audio with compatible LE Audio hearing aids, part of Android's work to enhance audio accessibility. Built on the LE Audio standard, Auracast enables compatible hearing aids and earbuds to receive direct audio streams from public venues like airports, concerts, and classrooms. Our Keyword post has more on this technology.

Outline text for maximum text contrast

Users with low vision often have reduced contrast sensitivity, making it challenging to distinguish objects from their backgrounds. To help these users, Android 16 Beta 3 introduces outline text, replacing high contrast text, which draws a larger contrasting area around text to greatly improve legibility.

Android 16 also contains new AccessibilityManager APIs to allow your apps to check or register a listener to see if this mode is enabled. This is primarily for UI Toolkits like Compose to offer a similar visual experience. If you maintain a UI Toolkit library or your app performs custom text rendering that bypasses the android.text.Layout class then you can use this to know when outline text is enabled.

Test your app with Local Network Protection

Android 16 Beta 3 adds the ability to test the Local Network Protection (LNP) feature which is planned for a future Android major release. It gives users more control over which apps can access devices on their local network.

What's Changing?

Currently, any app with the INTERNET permission can communicate with devices on the user's local network. LNP will eventually require apps to request a specific permission to access the local network.

Beta 3: Opt-In and Test

In Beta 3, LNP is an opt-in feature. This is your chance to test your app and identify any parts that rely on local network access. Use this adb command to enable LNP restrictions for your app:

adb shell am compat enable RESTRICT_LOCAL_NETWORK <your_package_name>

After rebooting your device, your app's local network access is restricted. Test features that might interact with local devices (e.g., device discovery, media casting, connecting to IoT devices). Expect to see socket errors like EPERM or ECONNABORTED if your app tries to access the local network without the necessary permission. See the developer guide for more information, including how to re-enable local network access.

This is a significant change, and we're committed to working with you to ensure a smooth transition. By testing and providing feedback now, you can help us build a more private and secure Android ecosystem.

Get your apps, libraries, tools, and game engines ready!

If you develop an SDK, library, tool, or game engine, it's even more important to prepare any necessary updates now to prevent your downstream app and game developers from being blocked by compatibility issues and allow them to target the latest SDK features. Please let your developers know if updates are needed to fully support Android 16.

Testing involves installing your production app or a test app making use of your library or engine using Google Play or other means onto a device or emulator running Android 16 Beta 3. Work through all your app's flows and look for functional or UI issues. Review the behavior changes to focus your testing. Each release of Android contains platform changes that improve privacy, security, and overall user experience, and these changes can affect your apps. Here are several changes to focus on that apply, even if you don't yet target Android 16:

    • JobScheduler: JobScheduler quotas are enforced more strictly in Android 16; enforcement will occur if a job executes while the app is on top, when a foreground service is running, or in the active standby bucket. setImportantWhileForeground is now a no-op. The new stop reason STOP_REASON_TIMEOUT_ABANDONED occurs when we detect that the app can no longer stop the job.
    • Broadcasts: Ordered broadcasts using priorities only work within the same process. Use other IPC if you need cross-process ordering.
    • ART: If you use reflection, JNI, or any other means to access Android internals, your app might break. This is never a best practice. Test thoroughly.
    • 16KB Page Size: If your app isn't 16KB-page-size ready, you can use the new compatibility mode flag, but we recommend migrating to 16KB for best performance.

Other changes that will be impactful once your app targets Android 16:

Remember to thoroughly exercise libraries and SDKs that your app is using during your compatibility testing. You may need to update to current SDK versions or reach out to the developer for help if you encounter any issues.

Once you’ve published the Android 16-compatible version of your app, you can start the process to update your app's targetSdkVersion. Review the behavior changes that apply when your app targets Android 16 and use the compatibility framework to help quickly detect issues.

Two Android API releases in 2025

This preview is for the next major release of Android with a planned launch in Q2 of 2025 and we plan to have another release with new developer APIs in Q4. This Q2 major release will be the only release in 2025 that includes behavior changes that could affect apps. The Q4 minor release will pick up feature updates, optimizations, and bug fixes; like our non-SDK quarterly releases, it will not include any intentional app-breaking behavior changes.

Android API release timeline 2025

We'll continue to have quarterly Android releases. The Q1 and Q3 updates provide incremental updates to ensure continuous quality. We’re putting additional energy into working with our device partners to bring the Q2 release to as many devices as possible.

There’s no change to the target API level requirements and the associated dates for apps in Google Play; our plans are for one annual requirement each year, tied to the major API level.

Get started with Android 16

You can enroll any supported Pixel device to get this and future Android Beta updates over-the-air. If you don’t have a Pixel device, you can use the 64-bit system images with the Android Emulator in Android Studio. If you are currently on Android 16 Beta 2 or are already in the Android Beta program, you will be offered an over-the-air update to Beta 3.

While the API and behaviors are final, we're still looking for your feedback so please report issues on the feedback page. The earlier we get your feedback, the better chance we'll be able to address it in this or a future release.

For the best development experience with Android 16, we recommend that you use the latest feature drop of Android Studio (Meerkat). Once you’re set up, here are some of the things you should do:

    • Compile against the new SDK, test in CI environments, and report any issues in our tracker on the feedback page.

We’ll update the beta system images and SDK regularly throughout the Android 16 release cycle. Once you’ve installed a beta build, you’ll automatically get future updates over-the-air for all later previews and Betas.

The Second Beta of Android 16

Posted by Matthew McCullough – VP of Product Management, Android Developer

Today we're releasing the second beta of Android 16, continuing our work to build a platform that enables creative expression. You can enroll any supported Pixel device to get this and future Android Beta updates over-the-air.

This build adds new support for professional camera experiences, graphical effects, extends our performance framework, and continues the evolution of features related to privacy, security, and background tasks. We’re looking forward to hearing what you think, and thank you in advance for your continued help in making Android a platform that works for everyone.

Media and camera updates

Android 16 enhances support for professional camera users, allowing for hybrid auto exposure along with precise color temperature and tint adjustments. It's easier than ever to capture motion photos with new Intent actions, and we're continuing to improve UltraHDR images, with support for HEIC encoding and new parameters from the ISO 21496-1 draft standard.

Hybrid auto-exposure

Android 16 adds new hybrid auto-exposure modes to Camera2, allowing you to manually control specific aspects of exposure while letting the auto-exposure (AE) algorithm handle the rest. You can control ISO + AE, and exposure time + AE, providing greater flexibility compared to the current approach where you either have full manual control or rely entirely on auto-exposure.

fun setISOPriority() {
   // ...

    val availablePriorityModes = mStaticInfo.characteristics.get(
        CameraCharacteristics.CONTROL_AE_AVAILABLE_PRIORITY_MODES
    )
    // ...
    
    // Turn on AE mode to set priority mode
    reqBuilder[CaptureRequest.CONTROL_AE_MODE] = CameraMetadata.CONTROL_AE_MODE_ON
    reqBuilder[CaptureRequest.CONTROL_AE_PRIORITY_MODE] = CameraMetadata.CONTROL_AE_PRIORITY_MODE_SENSOR_SENSITIVITY_PRIORITY
    reqBuilder[CaptureRequest.SENSOR_SENSITIVITY] = TEST_SENSITIVITY_VALUE
    val request: CaptureRequest = reqBuilder.build()

    // ...

}

Precise color temperature and tint adjustments

Android 16 adds camera support for fine color temperature and tint adjustments to better support professional video recording applications. White balance settings are currently controlled through CONTROL_AWB_MODE, which contains options limited to a preset list, such as Incandescent, Cloudy, and Twilight. The COLOR_CORRECTION_MODE_CCT enables the use of COLOR_CORRECTION_COLOR_TEMPERATURE and COLOR_CORRECTION_COLOR_TINT for precise adjustments of white balance based on the correlated color temperature.

fun setCCT() {
    // ... (Your existing code before this point) ...

    val colorTemperatureRange: Range<Int> =
        mStaticInfo.characteristics[CameraCharacteristics.COLOR_CORRECTION_COLOR_TEMPERATURE_RANGE]

    // Set to manual mode to enable CCT mode
    reqBuilder[CaptureRequest.CONTROL_AWB_MODE] = CameraMetadata.CONTROL_AWB_MODE_OFF
    reqBuilder[CaptureRequest.COLOR_CORRECTION_MODE] = CameraMetadata.COLOR_CORRECTION_MODE_CCT
    reqBuilder[CaptureRequest.COLOR_CORRECTION_COLOR_TEMPERATURE] = 5000
    reqBuilder[CaptureRequest.COLOR_CORRECTION_COLOR_TINT] = 30

    val request: CaptureRequest = reqBuilder.build()

    // ... (Your existing code after this point) ...
}
Five photos of the back of a Google Pixel phone demonstrate different color temperatures and tints. The original photo is in the top left, followed by Tint -50, Tint +50, Temp 3000, and Temp 7000.

Motion photo capture intent actions

Android 16 adds standard Intent actions — ACTION_MOTION_PHOTO_CAPTURE, and ACTION_MOTION_PHOTO_CAPTURE_SECURE — which request that the camera application capture a motion photo and return it.

You must either pass an extra EXTRA_OUTPUT to control where the image will be written, or a Uri through Intent setClipData. If you don't set a ClipData, it will be copied there for you when calling Context.startActivity.

UltraHDR image enhancements

A split-screen image compares Standard Dynamic Range (SDR) and High Dynamic Range (HDR) image quality side-by-side using a singular image of a detailed landscape. The HDR side is more vivid and vibrant.

Android 16 continues our work to deliver dazzling image quality with UltraHDR images. It adds support for UltraHDR images in the HEIC file format. These images will get ImageFormat type HEIC_ULTRAHDR and will contain an embedded gainmap similar to the existing UltraHDR JPEG format. We're working on AVIF support for UltraHDR as well, so stay tuned.

In addition, Android 16 implements additional parameters in UltraHDR from the ISO 21496-1 draft standard, including the ability to get and set the colorspace that gainmap math should be applied in, as well as support for HDR encoded base images with SDR gainmaps.

Custom graphical effects with AGSL

Android 16 adds RuntimeColorFilter and RuntimeXfermode, allowing you to author complex effects like Threshold, Sepia, and Hue Saturation and apply them to draw calls. Since Android 13, you've been able to use AGSL to create custom RuntimeShaders that extend Shaders. The new API mirrors this, adding an AGSL-powered RuntimeColorFilter that extends ColorFilters, and a Xfermode effect that allows you to implement AGSL-based custom compositing and blending between source and destination pixels.

private val thresholdEffectString = """
    uniform half threshold;
    half4 main(half4 c) {
        half luminosity = dot(c.rgb, half3(0.2126, 0.7152, 0.0722));
        half bw = step(threshold, luminosity);
        return bw.xxx1 * c.a;
    }"""

fun setCustomColorFilter(paint: Paint) {
   val filter = RuntimeColorFilter(thresholdEffectString)
   filter.setFloatUniform(0.5)
   paint.colorFilter = filter
}

Behavior changes

With every Android release, we seek to make the platform more efficient, privacy conscious, internationalization friendly, and robust, balancing the needs of apps against hardware support, system performance, user privacy, and battery life. This can result in behavior changes that impact compatibility.

Edge to edge opt-out going away

Android 15 enforced edge-to-edge for apps targeting Android 15 (SDK 35), but your app could opt-out by setting R.attr#windowOptOutEdgeToEdgeEnforcement to true. Once your app targets Android 16 (Baklava), R.attr#windowOptOutEdgeToEdgeEnforcement is deprecated and disabled and your app cannot opt-out of going edge-to-edge. To be compatible with Android 16 Beta 2, ensure your app supports edge-to-edge and remove any use of R.attr#windowOptOutEdgeToEdgeEnforcement. To support edge-to-edge, see the Compose and Views guidance. Please let us know about concerns in our tracker on the feedback page.

Health and fitness permissions

For apps targeting Android 16 or higher, BODY_SENSORS permissions are transitioning to the granular permissions under android.permissions.health also used by Health Connect. Any API previously requiring BODY_SENSORS or BODY_SENSORS_BACKGROUND will now require the corresponding android.permissions.health permission. This affects the following data types, APIs, and foreground service types:

If your app uses these APIs, it should now request the respective granular permissions:

These permissions are the same as those that guard access to reading data from Health Connect, the Android datastore for health, fitness, and wellness data.

Abandoned empty jobs stop reason

An abandoned job occurs when the JobParameters object associated with the job has been garbage collected, but jobFinished has not been called to signal job completion. This indicates that the job may be running and being rescheduled without the application's awareness.

Applications in Android 16 that rely on JobScheduler without maintaining a strong reference to the JobParameters object will now be granted the new job stop reason STOP_REASON_TIMEOUT_ABANDONED on timeout, instead of STOP_REASON_TIMEOUT.

If there are frequent occurrences of the new abandoned stop reason, the system will take mitigation steps to reduce job frequency. Please use the new stop reason to detect and reduce abandoned jobs.

Note: If you're using WorkManager, you're not expected to be impacted by this change — one nice side effect of using Android Jetpack to schedule your work.

Intent redirect changes

Android 16 introduces default security hardening against Intent redirection attacks regardless of your app's targetSDK version. The removeLaunchSecurityProtection API allows you to opt-out of this protection if your testing reveals issues.

Note: Opting out of security protections should be done with caution and only when absolutely necessary, as it can increase the risk of security vulnerabilities.
val iSublevel = intent.getParcelableExtra("sub_intent", Intent::class.java)
iSublevel?.let {
    it.removeLaunchSecurityProtection()
    startActivity(it)
}

Elegant font APIs deprecated and disabled

Apps targeting Android 15 (API level 35) have the elegantTextHeight TextView attribute set to true by default, replacing the compact font with one that is much more readable. You could override this by setting the elegantTextHeight attribute to false.

Android 16 deprecates the elegantTextHeight attribute, and the attribute will be ignored once your app targets Android 16. The “UI fonts” controlled by these APIs are being discontinued, so you should adapt any layouts to ensure consistent and future proof text rendering in Arabic, Lao, Myanmar, Tamil, Gujarati, Kannada, Malayalam, Odia, Telugu or Thai.

16 KB page size compatibility mode

Android 15 introduced support for 16KB memory pages to optimize performance of the platform. Android 16 adds a compatibility mode, allowing some apps built for 4K memory pages to run on a device configured for 16KB memory pages.

If Android detects that your app has 4KB aligned memory pages, it will automatically use compatibility mode and display a notification dialog to the user. Setting the android:pageSizeCompat property in the AndroidManifest.xml to enable the backwards compatibility mode will prevent the display of the dialog when your app launches. For best performance, reliability, and stability, your app should still be 16KB aligned. Read our recent blog post about updating your apps to support 16KB memory pages for more details.

Measurement system customization

Users can now customize their measurement system in regional preferences within Settings. The user preference is included as part of the locale code, so you can register a BroadcastReceiver on ACTION_LOCALE_CHANGED to handle locale configuration changes when regional preferences change.

Using formatters can help match the local experience. For example, "0.5 in" in English (United States), is "12,7 mm" for a user who has set their phone to English (Denmark) or who uses their phone in English (United States) with the metric system as the measurement system preference.

To find these settings in Android 16 Beta 2, open the Settings app and navigate to System > Languages & region.

Content handling for live wallpapers

In Android 16, the live wallpaper framework is gaining a new content API to address the challenges of dynamic, user-driven wallpapers. Currently, live wallpapers incorporating user-provided content require complex, service-specific implementations. Android 16 introduces WallpaperDescription and WallpaperInstance. WallpaperDescription allows you to identify distinct instances of a live wallpaper from the same service. For example, a wallpaper that has instances on both the home screen and on the lock screen may have unique content in both places. The wallpaper picker and WallpaperManager use this metadata to better present wallpapers to users, streamlining the process for you to create diverse and personalized live wallpaper experiences.

Headroom APIs in ADPF

The SystemHealthManager introduces the getCpuHeadroom and getGpuHeadroom APIs, designed to provide games and resource-intensive apps with estimates of available CPU and GPU resources. These methods offer a way for you to gauge how your app or game can best improve system health, particularly when used in conjunction with other Android Dynamic Performance Framework (ADPF) APIs that detect thermal throttling. By using CpuHeadroomParams and GpuHeadroomParams on supported devices, you will be able to customize the time window used to compute the headroom and select between average or minimum resource availability. This can help you reduce your CPU or GPU resource usage accordingly, leading to better user experiences and improved battery life.

Key sharing API

Android 16 adds APIs that support sharing access to Android Keystore keys with other apps. The new KeyStoreManager class supports granting and revoking access to keys by app uid, and includes an API for apps to access shared keys.

Standardized picture and audio quality framework for TVs

The new MediaQuality package in Android 16 exposes a set of standardized APIs for access to audio and picture profiles and hardware-related settings. This allows streaming apps to query profiles and apply them to media dynamically:

    • Movies mastered with a wider dynamic range require greater color accuracy to see subtle details in shadows and adjust to ambient light, so a profile that prefers color accuracy over brightness may be appropriate.
    • Live sporting events are often mastered with a narrow dynamic range, but are often watched in daylight, so a profile that gives preference to brightness over color accuracy can give better results.
    • Fully interactive content wants minimal processing to reduce latency, and wants higher frame rates, which is why many TV's ship with a game profile.

The API allows apps to switch between profiles and users to enjoy the benefits of tuning supported TVs to best suit their content.

Accessibility

Android 16 adds additional APIs to enhance UI semantics that help improve consistency for users that rely on accessibility services, such as TalkBack.

Duration added to TtsSpan

Android 16 extends TtsSpan with a TYPE_DURATION, consisting of ARG_HOURS, ARG_MINUTES, and ARG_SECONDS. This allows you to directly annotate time duration, ensuring accurate and consistent text-to-speech output with services like TalkBack.

Support elements with multiple labels

Android currently allows UI elements to derive their accessibility label from another, and now offers the ability for multiple labels to be associated, a common scenario in web content. By introducing a list-based API within AccessibilityNodeInfo, Android can directly support these multi-label relationships. As part of this change, we've deprecated AccessibilityNodeInfo setLabeledBy and getLabeledBy in favor of addLabeledBy, removeLabeledBy, and getLabeledByList.

Improved support for expandable elements

Android 16 adds accessibility APIs that allow you to convey the expanded or collapsed state of interactive elements, such as menus and expandable lists. By setting the expanded state using setExpandedState and dispatching TYPE_WINDOW_CONTENT_CHANGED AccessibilityEvents with a CONTENT_CHANGE_TYPE_EXPANDED content change type, you can ensure that screen readers like TalkBack announce state changes, providing a more intuitive and inclusive user experience.

Indeterminate ProgressBars

Android 16 adds RANGE_TYPE_INDETERMINATE, giving a way for you to expose RangeInfo for both determinate and indeterminate ProgressBar widgets, allowing services like TalkBack to more consistently provide feedback for progress indicators.

Tri-state CheckBox

The new AccessibilityNodeInfo getChecked and setChecked(int) methods in Android 16 now support a "partially checked" state in addition to "checked" and "unchecked." This replaces the deprecated boolean isChecked and setChecked(boolean).

Two Android API releases in 2025

This preview is for the next major release of Android with a planned launch in Q2 of 2025 and we plan to have another release with new developer APIs in Q4. The Q2 major release will be the only release in 2025 to include behavior changes that could affect apps. The Q4 minor release will pick up feature updates, optimizations, and bug fixes; like our non-SDK quarterly releases, it will not include any intentional app-impacting behavior changes.

2025 SDK release timeline showing a features only update in Q1 and Q3, a major SDK release with behavior changes, APIs, and features in Q2, and a minor SDK release with APIs and features in Q4

We'll continue to have quarterly Android releases. The Q1 and Q3 updates provide incremental updates to ensure continuous quality. We’re putting additional energy into working with our device partners to bring the Q2 release to as many devices as possible.

There’s no change to the target API level requirements and the associated dates for apps in Google Play; our plans are for one annual requirement each year, tied to the major API level.

How to get ready

In addition to performing compatibility testing on this next major release, make sure that you're compiling your apps against the new SDK, and use the compatibility framework to enable targetSdkVersion-gated behavior changes as they become available for early testing.

App compatibility

The Android 16 production timeline shows the release stages, highlighting 'Beta Releases' and 'Platform Stability' in blue and green, respectively, from December to the final release.

The Android 16 Preview program runs from November 2024 until the final public release in Q2 of 2025. At key development milestones, we'll deliver updates for your development and testing environments. Each update includes SDK tools, system images, emulators, API reference, and API diffs. We'll highlight critical APIs as they are ready to test in the preview program in blogs and on the Android 16 developer website.

We’re targeting March of 2025 for our Platform Stability milestone. At this milestone, we’ll deliver final SDK/NDK APIs and also final internal APIs and app-facing system behaviors. From that time you’ll have several months before the final release to complete your testing. Learn more by checking the release timeline details.

Get started with Android 16

You can enroll any supported Pixel device to get this and future Android Beta updates over-the-air. If you don’t have a Pixel device, you can use the 64-bit system images with the Android Emulator in Android Studio. If you are currently on Android 16 Beta 1 or are already in the Android Beta program, you will be offered an over-the-air update to Beta 2.

We're looking for your feedback so please report issues and submit feature requests on the feedback page. The earlier we get your feedback, the more we can include in our work on the final release.

For the best development experience with Android 16, we recommend that you use the latest preview of Android Studio (Meerkat). Once you’re set up, here are some of the things you should do:

    • Compile against the new SDK, test in CI environments, and report any issues in our tracker on the feedback page.
    • Test your current app for compatibility, learn whether your app is affected by changes in Android 16, and install your app onto a device or emulator running Android 16 and extensively test it.

We’ll update the beta system images and SDK regularly throughout the Android 16 release cycle. Once you’ve installed a beta build, you’ll automatically get future updates over-the-air for all later previews and Betas.

For complete information, visit the Android 16 developer site.

The First Beta of Android 16

Posted by Matthew McCullough – VP of Product Management, Android Developer

The first beta of Android 16 is now available, which means it's time to open the experience up to both developers and early adopters. You can now enroll any supported Pixel device here to get this and future Android Beta updates over-the-air.

This build includes support for the future of app adaptivity, Live Updates, the Advanced Professional Video format, and more. We’re looking forward to hearing what you think, and thank you in advance for your continued help in making Android a platform that works for everyone.

Android adaptive apps

Users expect apps to work seamlessly on all their devices, regardless of display size and form factor. To that end, Android 16 is phasing out the ability for apps to restrict screen orientation and resizability on large screens. This is similar to features OEMs have added over the last several years to large screen devices to allow users to run apps at any window size and aspect ratio.

On screens larger than 600dp wide, apps that target API level 36 will have app windows that resize; you should check your apps to ensure your existing UIs scale seamlessly, working well across portrait and landscape aspect ratios. We're providing frameworks, tooling, and libraries to help.

Key changes:

Timeline:

Live Updates

Live Updates are a new class of notifications that help users monitor and quickly access important ongoing activities.

The new ProgressStyle notification template provides a consistent user experience for Live Updates, helping you build for these progress-centric user journeys: rideshare, delivery, and navigation. It includes support for custom icons for the start, end, and current progress tracking, segments and points, user journey states, milestones, and more.

ProgressStyle notifications are suggested only for ride sharing, food delivery, and navigation use cases.

@Override
protected Notification getNotification() {
   return new Notification.Builder(mContext, CHANNEL_ID)
      .setSmallIcon(R.drawable.ic_app_icon)
      .setContentTitle("Ride requested")
      .setContentText("Looking for nearby drivers")
      .setStyle(
          new Notification.ProgressStyle()
          .addProgressSegment(
              new Notification.ProgressStyle.Segment(100)
                  .setColor(COLOR_ORANGE)
           ).setProgressIndeterminate(true)
      ).build();
}

Camera and media updates

Android 16 advances support for the playback, creation, and editing of high-quality media, a critical use case for social and productivity apps.

Advanced Professional Video

Android 16 introduces support for the Advanced Professional Video (APV) codec which is designed to be used for professional level high quality video recording and post production.

The APV codec standard has the following features:

    • Perceptually lossless video quality (close to raw video quality)
    • Low complexity and high throughput intra-frame-only coding (without pixel domain prediction) to better support editing workflows
    • Support for high bit-rate range up to a few Gbps for 2K, 4K and 8K resolution content, enabled by a lightweight entropy coding scheme
    • Frame tiling for immersive content and for enabling parallel encoding and decoding
    • Support for various chroma sampling formats and bit-depths
    • Support for multiple decoding and re-encoding without severe visual quality degradation
    • Support multi-view video and auxiliary video like depth, alpha, and preview
    • Support for HDR10/10+ and user-defined metadata

A reference implementation of APV is provided through the OpenAPV project. Android 16 will implement support for the APV 422-10 Profile that provides YUV 422 color sampling along with 10-bit encoding and for target bitrates of up to 2Gbps.

Camera night mode scene detection

To help your app know when to switch to and from a night mode camera session, Android 16 adds EXTENSION_NIGHT_MODE_INDICATOR. If supported, it's available in the CaptureResult within Camera2.

This is the API we briefly mentioned as coming soon in the "How Instagram enabled users to take stunning low light photos" blogpost. That post is a practical guide on how to implement night mode together with a case study that links higher-quality, in-app, night mode photos with an increase in the number of photos shared from the in-app camera.

Vertical Text

Android 16 adds low-level support for rendering and measuring text vertically to provide foundational vertical writing support for library developers. This is particularly useful for languages like Japanese that commonly use vertical writing systems. A new flag, VERTICAL_TEXT_FLAG, has been added to the Paint class. When this flag is set using Paint.setFlags, Paint’s text measurement APIs will report vertical advances instead of horizontal advances, and Canvas will draw text vertically.

Note: Current high level text APIs, such as Text in Jetpack Compose, TextView, Layout classes and their subclasses do not support vertical writing systems, and do not support using the VERTICAL_TEXT_FLAG.
val text = "「春は、曙。」"
Box(Modifier
  .padding(innerPadding)
  .background(Color.White)
  .fillMaxSize()
  .drawWithContent {
     drawIntoCanvas { canvas ->
       val paint = Paint().apply {
         textSize = 64.sp.toPx()
       }
       // Draw text vertically
       paint.flags = paint.flags or VERTICAL_TEXT_FLAG
       val height = paint.measureText(text)
       canvas.nativeCanvas.drawText(
         text, 0, text.length, size.width / 2, (size.height - height) / 2, paint
       )
     }
  }) 
{}

Accessibility

Android 16 adds new accessibility APIs to help you bring your app to every user.

Supplemental descriptions

When an accessibility service describes a ViewGroup, it combines content labels from its child views. If you provide a contentDescription for the ViewGroup, accessibility services assume you are also overriding the content of non-focusable child views. This can be problematic if you want to label things like a drop down (e.g. "Font Family") while preserving the current selection for accessibility (e.g. "Roboto"). Android 16 adds setSupplementalDescription so you can provide text that provides information about a ViewGroup without overriding information from its children.

Required form fields

Android 16 adds setFieldRequired to AccessibilityNodeInfo so apps can tell an accessibility service that input to a form field is required. This is an important scenario for users filling out many types of forms, even things as simple as a required terms and conditions checkbox, helping users to consistently identify and quickly navigate between required fields.

Generic ranging APIs

Android 16 includes the new RangingManager, which provides ways to determine the distance and angle on supported hardware between the local device and a remote device. RangingManager supports the usage of a variety of ranging technologies such as BLE channel sounding, BLE RSSI-based ranging, Ultra-Wideband, and WiFi round trip time.

Behavior changes

With every Android release, we seek to make the platform more efficient and robust, balancing the needs of your apps against things like system performance and battery life. This can result in behavior changes that impact compatibility.

ART internal changes

Code that leverages internal structures of the Android Runtime (ART) may not work correctly on devices running Android 16 along with earlier Android versions that update the ART module through Google Play system updates. These structures are changing in ways that help improve the Android Runtime's (ART's) performance.

Impacted apps will need to be updated. Relying on internal structures can always lead to compatibility problems, but it's particularly important to avoid relying on code (or libraries containing code) that leverages internal ART structures, since ART changes aren't tied to the platform version the device is running on; they go out to over a billion devices through Google Play system updates.

For more information, see the Android 16 changes affecting all apps and the restrictions on non-SDK interfaces.

Migration or opt-out required for predictive back

For apps targeting Android 16 or higher and running on an Android 16 or higher device, the predictive back system animations (back-to-home, cross-task, and cross-activity) are enabled by default. Additionally, the deprecated onBackPressed is not called and KeyEvent.KEYCODE_BACK is no longer dispatched.

If your app intercepts the back event and you haven't migrated to predictive back yet, update your app to use supported back navigation APIs or temporarily opt out by setting the android:enableOnBackInvokedCallback attribute to false in the <application> or <activity> tag of your app’s AndroidManifest.xml file.

Predictive back support for 3-button navigation

Android 16 brings predictive back support to 3-button navigation for apps that have properly migrated to predictive back. Long-pressing the back button initiates a predictive back animation, giving users a preview of where the back button takes them.

This behavior applies across all areas of the system that support predictive back animations, including the system animations (back-to-home, cross-task, and cross-activity).

Fixed rate work scheduling optimization

Prior to targeting Android 16, when scheduleAtFixedRate missed a task execution due to being outside a valid process lifecycle, all missed executions will immediately execute when app returns to a valid lifecycle.

When targeting Android 16, at most one missed execution of scheduleAtFixedRate will be immediately executed when the app returns to a valid lifecycle. This behavior change is expected to improve app performance. Please test the behavior to ensure your application is not impacted. You can also test by using the app compatibility framework and enabling the STPE_SKIP_MULTIPLE_MISSED_PERIODIC_TASKS compat flag.

Ordered broadcast priority scope no longer global

In Android 16, broadcast delivery order using the android:priority attribute or IntentFilter#setPriority() across different processes will not be guaranteed. Broadcast priorities for ordered broadcasts will only be respected within the same application process rather than across all system processes.

Additionally, broadcast priorities will be automatically confined to the range (SYSTEM_LOW_PRIORITY + 1, SYSTEM_HIGH_PRIORITY - 1).

Your application may be impacted if it does either of the following:

      1. Your application has declared multiple processes that have set broadcast receiver priorities for the same intent.

      2. Your application process interacts with other processes and has expectations around receiving a broadcast intent in a certain order.

If the processes need to coordinate with each other, they should communicate using other coordination channels.

Gemini Extensions

Samsung just launched new Gemini Extensions on the S25 series, demonstrating new ways Android apps can integrate with the power of Gemini. We're working to make this functionality available on even more form factors.

Two Android API releases in 2025

This preview is for the next major release of Android with a planned launch in Q2 of 2025 and we plan to have another release with new developer APIs in Q4. The Q2 major release will be the only release in 2025 to include planned behavior changes that could affect apps. The Q4 minor release will pick up feature updates, optimizations, and bug fixes; it will not include any app-impacting behavior changes.

2025 SDK release timeline showing a features only update in Q1 and Q3, a major SDK release with behavior changes, APIs, and features in Q2, and a minor SDK release with APIs and features in Q4

We'll continue to have quarterly Android releases. The Q1 and Q3 updates, which will land in-between the Q2 and Q4 API releases, will provide incremental updates to ensure continuous quality. We’re putting additional energy into working with our device partners to bring the Q2 release to as many devices as possible.

There’s no change to the target API level requirements and the associated dates for apps in Google Play; our plans are for one annual requirement each year, tied to the major API level.

How to get ready

In addition to performing compatibility testing on this next major release, make sure that you're compiling your apps against the new SDK, and use the compatibility framework to enable targetSdkVersion-gated behavior changes as they become available for early testing.

App compatibility

The Android 16 production timeline shows the release stages, highlighting 'Beta Releases' and 'Platform Stability' in blue and green, respectively, from December to the final release.

The Android 16 Preview program runs from November 2024 until the final public release in Q2 of 2025. At key development milestones, we'll deliver updates for your development and testing environments. Each update includes SDK tools, system images, emulators, API reference, and API diffs. We'll highlight critical APIs as they are ready to test in the preview program in blogs and on the Android 16 developer website.

We’re targeting March of 2025 for our Platform Stability milestone. At this milestone, we’ll deliver final SDK/NDK APIs and also final internal APIs and app-facing system behaviors. From that time you’ll have several months before the final release to complete your testing. The release timeline details are here.

Get started with Android 16

Now that we've entered the beta phase, you can enroll any supported Pixel device to get this and future Android Beta updates over-the-air. If you don’t have a Pixel device, you can use the 64-bit system images with the Android Emulator in Android Studio.

If you are currently on Android 16 Developer Preview 2 or are already in the Android Beta program, you will be offered an over-the-air update to Beta 1.

If you are in Android 25Q1 Beta and would like to take the final stable release of 25Q1 and exit Beta, you need to ignore the over-the-air update to 25Q2 Beta 1 and wait for the release of 25Q1.

We're looking for your feedback so please report issues and submit feature requests on the feedback page. The earlier we get your feedback, the more we can include in our work on the final release.

For the best development experience with Android 16, we recommend that you use the latest preview of Android Studio (Meerkat). Once you’re set up, here are some of the things you should do:

    • Compile against the new SDK, test in CI environments, and report any issues in our tracker on the feedback page.
    • Test your current app for compatibility, learn whether your app is affected by changes in Android 16, and install your app onto a device or emulator running Android 16 and extensively test it.

We’ll update the preview/beta system images and SDK regularly throughout the Android 16 release cycle. Once you’ve installed a beta build, you’ll automatically get future updates over-the-air for all later previews and Betas.

The Second Developer Preview of Android 16

Posted by Matthew McCullough – VP of Product Management, Android Developer


The second developer preview of Android 16 is now available to test with your apps. This build includes changes designed to enhance the app experience, improve battery life, and boost performance while minimizing incompatibilities, and your feedback is critical in helping us understand the full impact of this work.

System triggered profiling

ProfilingManager was added in Android 15, giving apps the ability to request profiling data collection using Perfetto on public devices in the field. To help capture challenging trace scenarios such as startups or ANRs, ProfilingManager now includes System Triggered Profiling. Apps can use ProfilingManager#addProfilingTriggers() to register interest in receiving information about these flows. Flows covered in this release include onFullyDrawn for activity based cold starts, and ANRs.

val anrTrigger = ProfilingTrigger.Builder(
                ProfilingTrigger.TRIGGER_TYPE_ANR
            )
                .setRateLimitingPeriodHours(1)
                .build()

val startupTrigger: ProfilingTrigger =  //...

mProfilingManager.addProfilingTriggers(listOf(anrTrigger, startupTrigger))

Start component in ApplicationStartInfo

ApplicationStartInfo was added in Android 15, allowing an app to see reasons for process start, start type, start times, throttling, and other useful diagnostic data. Android 16 adds getStartComponent() to distinguish what component type triggered the start, which can be helpful for optimizing the startup flow of your app.

Richer Haptics

Android has exposed limited control over the haptic actuator since its inception.

Android 11 added support for more complex haptic effects that more advanced actuators can support through VibrationEffect.Compositions of device-defined semantic primitives.

Android 16 adds haptic APIs that let apps define the amplitude and frequency curves of a haptic effect while abstracting away differences between device capabilities.

Better job introspection

Android 16 introduces JobScheduler#getPendingJobReasons(int jobId) which can return multiple reasons why a job is pending, due to both explicit constraints set by the developer and implicit constraints set by the system.

We're also introducing JobScheduler#getPendingJobReasonsHistory(int jobId), which returns a list of the most recent constraint changes.

The API can help you debug why your jobs may not be executing, especially if you're seeing reduced success rates with certain tasks or latency issues with job completion as well. This can also better help you understand if certain jobs are not completing due to system defined constraints versus explicitly set constraints.

Adaptive refresh rate

Adaptive refresh rate (ARR), introduced in Android 15, enables the display refresh rate on supported hardware to adapt to the content frame rate using discrete VSync steps. This reduces power consumption while eliminating the need for potentially jank-inducing mode-switching.

Android 16 DP2 introduces hasArrSupport() and getSuggestedFrameRate(int) while restoring getSupportedRefreshRates() to make it easier for your apps to take advantage of ARR.

RecyclerView 1.4 internally supports ARR when it is settling from a fling or smooth scroll, and we're continuing our work to add ARR support into more Jetpack libraries. This frame rate article covers many of the APIs you can use to set the frame rate so that your app can directly leverage ARR.

Job execution optimizations

Starting in Android 16, we're adjusting regular and expedited job execution runtime quota based on the following factors:

    • Which app standby bucket the application is in; active standby buckets will be given a generous runtime quota.
    • Jobs started while the app is visible to the user and continues after the app becomes invisible will adhere to the job runtime quota.
    • Jobs that are executing concurrently with a foreground service will adhere to the job runtime quota. If you need to perform a data transfer that may take a long time consider using a user initiated data transfer.
Note: To understand how to further debug and test the behavior change, read more about JobScheduler quota optimizations.

Fully deprecating JobInfo#setImportantWhileForeground

The JobInfo.Builder#setImportantWhileForeground(boolean) method indicates the importance of a job while the scheduling app is in the foreground or when temporarily exempted from background restrictions.

This method has been deprecated since Android 12 (API 31). Starting in Android 16, it will no longer function effectively and calling this method will be ignored.

This removal of functionality also applies to JobInfo#isImportantWhileForeground(). Starting in Android 16, if the method is called, the method will return false.

Deprecated Disruptive Accessibility Announcements

Android 16 DP2 deprecates accessibility announcements, characterized by the use of announceForAccessibility or the dispatch of TYPE_ANNOUNCEMENT AccessibilityEvents. They can create inconsistent user experiences for users of TalkBack and Android's screen reader, and alternatives better serve a broader range of user needs across a variety of Android's assistive technologies.

Examples of alternatives:

The deprecated announceForAccessibility API includes more detail on suggested alternatives.

Cloud search in photo picker

The photo picker provides a safe, built-in way for users to grant your app access to selected images and videos from both local and cloud storage, instead of their entire media library. Using a combination of Modular System Components through Google System Updates and Google Play services, it's supported back to Android 4.4 (API level 19). Integration requires just a few lines of code with the associated Android Jetpack library.

The developer preview includes new APIs to enable searching from the cloud media provider for the Android photo picker. Search functionality in the photo picker is coming soon.

Ranging with enhanced security

Android 16 adds support for robust security features in WiFi location on supported devices with WiFi 6's 802.11az, allowing apps to combine the higher accuracy, greater scalability, and dynamic scheduling of the protocol with security enhancements including AES-256-based encryption and protection against MITM attacks. This allows it to be used more safely in proximity use cases, such as unlocking a laptop or a vehicle door. 802.11az is integrated with the Wi-Fi 6 standard, leveraging its infrastructure and capabilities for wider adoption and easier deployment.

Health Connect updates

Health Connect in the developer preview adds ACTIVITY_INTENSITY, a new datatype defined according to World Health Organization guidelines around moderate and vigorous activity. Each record requires the start time, the end time and whether the activity intensity is moderate or vigorous.

Health Connect also contains updated APIs supporting health records. This allows apps to read and write medical records in FHIR format with explicit user consent. This API is currently in an early access program. Sign up if you'd like to be part of our early access program.

Predictive back additions

Android 16 adds new APIs to help you enable predictive back system animations in gesture navigation such as the back-to-home animation. Registering the onBackInvokedCallback with the new PRIORITY_SYSTEM_NAVIGATION_OBSERVER allows your app to receive the regular onBackInvoked call whenever the system handles a back navigation without impacting the normal back navigation flow.

Android 16 additionally adds the finishAndRemoveTaskCallback() and moveTaskToBackCallback(). By registering these callbacks with the OnBackInvokedDispatcher, the system can trigger specific behaviors and play corresponding ahead-of-time animations when the back gesture is invoked.

Two Android API releases in 2025

This preview is for the next major release of Android with a planned launch in Q2 of 2025 and we plan to have another release with new developer APIs in Q4. The Q2 major release will be the only release in 2025 to include planned behavior changes that could affect apps. The Q4 minor release will pick up feature updates, optimizations, and bug fixes; it will not include any app-impacting behavior changes.

2025 SDK release timeline showing a features only update in Q1 and Q3, a major SDK release with behavior changes, APIs, and features in Q2, and a minor SDK release with APIs and features in Q4

We'll continue to have quarterly Android releases. The Q1 and Q3 updates in-between the API releases will provide incremental updates to help ensure continuous quality. We’re actively working with our device partners to bring the Q2 release to as many devices as possible.

There’s no change to the target API level requirements and the associated dates for apps in Google Play; our plans are for one annual requirement each year, and that will be tied to the major API level.

We'll highlight critical APIs as they are ready to test in the preview program in blogs and on the Android 16 developer website.

We’re targeting Late Q1 of 2025 for our Platform Stability milestone. At this milestone, we’ll deliver final SDK/NDK APIs and also final internal APIs and app-facing system behaviors. We’re expecting to reach Platform Stability in March 2025, and from that time you’ll have several months before the official release to do your final testing. Learn more in the release timeline details.

Get started with Android 16

You can get started today with Developer Preview 2 by flashing a system image and updating the tools. If you are currently on Developer Preview 1, you will automatically get an over-the-air update to Developer Preview 2. We're looking for your feedback so please report issues and submit feature requests on the feedback page. The earlier we get your feedback, the more we can include in the final release.

For the best development experience with Android 16, we recommend that you use the latest preview of the Android Studio Ladybug feature drop. Once you’re set up, here are some of the things you should do:

    • Compile against the new SDK, test in CI environments, and report any issues in our tracker on the feedback page.
    • Test your current app for compatibility, learn whether your app is affected by changes in Android 16, and install your app onto a device or emulator running Android 16 and extensively test it.

We’ll update the preview system images and SDK regularly throughout the Android 16 release cycle. This preview release is for developers only and not intended for daily consumer use. We're making it available by manual download. Once you’ve manually installed a preview build, you’ll automatically get future updates over-the-air for all later previews and Betas.

If you've already installed Android 15 QPR Beta 2 and would like to flash Android 16 Developer Preview 2, you can do so without first having to wipe your device.

As we reach our Beta releases, we'll be inviting consumers to try Android 16 as well, and we'll open up enrollment for Android 16 in the Android Beta program at that time.

The First Developer Preview of Android 16

Posted by Matthew McCullough – VP of Product Management, Android Developer


Android 16 Developer Preview 1 is available now to test with your apps. This is the start of Android having more frequent API releases as part of our effort to drive faster innovation in apps and devices.

Two Android API releases in 2025

    • This preview is for the next major release of Android with a planned launch in Q2 of 2025. This release is similar to all of our API releases in the past, where we can have planned behavior changes that are often tied to a targetSdkVersion.
    • We’re planning the major release a quarter earlier (Q2 rather than Q3 in prior years) to better align with the schedule of device launches across our ecosystem, so more devices can get the major release of Android sooner. With the major release coming in Q2, you’ll need to do your annual compatibility testing a few months earlier than in previous years to make sure your apps are ready.
    • We plan to have another release in Q4 of 2025 which also will include new developer APIs. The Q2 major release will be the only release in 2025 to include planned behavior changes that could affect apps.

In addition to new developer APIs, the Q4 minor release will pick up feature updates, optimizations, and bug fixes; it will not include any app-impacting behavior changes.

A timeline shows the release schedule for software development kits (SDKs), marked as 25Q1 through 25Q4.  25Q2 is a major release with behavior changes, APIs, and features, while 25Q4 is a minor release with APIs and features; 25Q1 and 25Q3 include features only.

We'll continue to have quarterly Android releases. The Q1 and Q3 updates in-between the API releases will provide incremental updates to help ensure continuous quality. We’re actively working with our device partners to bring the Q2 release to as many devices as possible.

Using new APIs with major and minor releases

Guarding a code block with a check for Android's API level is done today using the SDK_INT constant with VERSION_CODES. This will continue to be supported for major Android releases.

if (SDK_INT >= VERSION_CODES.BAKLAVA) {
  // Use APIs introduced in Android 16
}

The new SDK_INT_FULL constant can be used for API checks against both major and minor versions with the new VERSION_CODES_FULL enumeration.

if (SDK_INT_FULL >= VERSION_CODES_FULL.[MAJOR or MINOR RELEASE]) {
  // Use APIs introduced in a major or minor release
}

You can also use the Build.getMinorSdkVersion() method to get just the minor SDK version.

val minorSdkVersion = Build.getMinorSdkVersion(VERSION_CODES_FULL.BAKLAVA)

These APIs have not yet been finalized and are subject to change, so please send us feedback if you have any concerns.

Note that there’s no change to the target API level requirements and the associated dates for apps in Google Play; our plans are for one annual requirement each year, and that will be tied to the major API level.

Embedded photo picker

The photo picker provides a safe, built-in way for users to grant your app access to selected images and videos from both local and cloud storage, instead of their entire media library. Using a combination of Modular System Components through Google System Updates and Google Play services, it's supported back to Android 4.4 (API level 19). Integration requires just a few lines of code with the associated Android Jetpack library.

The developer preview includes new APIs that enable apps to embed the photo picker into their view hierarchy. This allows it to feel like a more integrated part of the app while still leveraging the process isolation that allows users to select media without the app needing overly-broad permissions. To maximize compatibility across platform versions and simplify your integration, you'll want to use the forthcoming Android Jetpack library if you wish to integrate the embedded photo picker.

Health records

The developer preview of Health Connect contains an early version of APIs supporting health records. This allows apps to read and write medical records in FHIR format with explicit user consent. This API is currently in an early access program. Sign up to be part of our early access program.

Privacy Sandbox on Android

Android 16 incorporates the latest version of the Privacy Sandbox on Android, part of our ongoing work to develop technologies where users know their privacy is protected. Our website has more about the Privacy Sandbox on Android developer beta program to help you get started. Check out the SDK Runtime which allows SDKs to run in a dedicated runtime environment separate from the app they are serving, providing stronger safeguards around user data collection and sharing.

How to get ready

In addition to performing compatibility testing on the next major release, make sure that you're compiling your apps against the new SDK, and use the compatibility framework to enable targetSdkVersion-gated behavior changes as they become available for early testing.
