Platform Stability milestone

Android 15 includes a milestone called Platform Stability to help you plan your final testing and releases. This milestone means that Android 15 has reached final internal and external APIs, final app-facing behaviors, and final non-SDK API lists. We expect Android 15 to reach Platform Stability at Beta 3 in June 2024. From that point, you can expect no further changes affecting your apps.

We encourage all app, game, SDK, library, and game engine developers to use the Platform Stability milestone as a target for planning final compatibility testing and public release. Using Platform Stability instead of final release gives you several additional weeks before consumers can receive the new platform on their devices.

Preview phases

Each phase of the preview program helps you prepare your apps for the stable release of AOSP and the Android ecosystem.

Developer Previews 1 and 2

During the Developer Previews, you should focus on API feedback and app compatibility. App compatibility means making sure the current version of your app looks right and runs well on the new platform.

The Developer Preview builds provide an early test and development environment you can use to try new APIs, identify compatibility issues in your app, and plan migration or feature work needed to target the new platform. It's especially important to give us your feedback during this time. You should also expect some API changes with each of these updates. Review the migration guide for steps to make your app compatible with the new platform, and then target the new platform when you're ready.

Beta 1

Beta 1 gives you a more complete and stable environment for building and testing on Android 15, and it's the first build that we deliver to early adopters who are enrolled in the Android Beta program. During the Beta releases period, early adopters will be using your app on Pixel devices, so we recommend watching for feedback from those users and releasing compatible updates to address any issues, without changing the app's targeting. It's also a good time to begin preparing for changing your app's targeting later.

Beta 2

With Beta 2, you'll get a more complete and stable build for continuing your testing and development.

Beta 3

Starting with Beta 3, Android 15 reaches Platform Stability, meaning that system behaviors and APIs are finalized. This is the time to begin final testing and development work needed to ensure that a compatible version of your app will be ready for users at the final release to the ecosystem. Android 15 will provide a standard API level at this time.

Platform Stability is the time to shift focus to final compatibility testing and release your updated apps to users and downstream developers. You can also build with the final APIs and refine any code that is using the new APIs or features. You can plan your work with confidence that the platform and APIs won't change.

From Platform Stability, you'll also be able to publish apps to devices running Android 15 at the official API level. We recommend publishing into the Google Play alpha and beta tracks first so that you can test your apps before distributing broadly through the store.

Beta 4, ...

With Beta 4 and other final beta releases, we'll offer release candidate builds for your final testing. When you've finished testing, you should release compatible updates for your apps, SDKs, libraries, tools, and game engines to ensure that users who upgrade their devices around the final release have a good user experience. You can also continue to build new capabilities using new features and APIs and test your app while targeting the latest API level to discover issues that might arise.

Final release

The stable version of Android 15 is released to AOSP and the greater Android ecosystem. You should expect that some of your users will update to Android 15 at this time or shortly thereafter as device manufacturers start to release updates for their users. Be prepared for new issues that might be reported as the number of users on the latest version of Android increases.

What's included in the Android 15 Preview?

Preview APIs and publishing

The Android 15 Preview program initially provides a development-only system and Android library that does not have a standard API level. If you want to target the new platform and build with the new Android 15 APIs during this time, you must target the Preview version of Android 15 by updating your app's build configuration.

The Android 15 Preview delivers preview APIs—the APIs won't be official until the final SDK is released at Platform Stability. This means that you should expect API changes over time, especially during the initial weeks of the program. We'll provide a summary of changes with each release of Android 15.

Later in the preview, developer APIs will be finalized and you'll be able to download the official Android 15 SDK into Android Studio, target the official API level, and compile against the official APIs.

Until the Platform Stability milestone, Google Play prevents publishing of apps that target either the VanillaIceCream preview API level or the future official API level. When the final SDK is available, you can then target the official Android 15 API level and publish your app to Google Play using the alpha, beta, and production release channels. Meanwhile, if you want to distribute an app to testers that targets Android 15, you can do so through email or by direct download from your site at any time.

Keep up-to-date

Throughout the preview, as you test on Developer Preview and Beta releases, we strongly recommend keeping your development environment up-to-date. We'll notify you when new updates are available using the following channels:

More information

To learn more about Android 15, see the following documentation resources:

  • The feature and changes list page provides a summary of all the notable features and behavior changes in this release, including a short description of the apps that they might affect.
  • The behavior changes for all apps page describes the updates in Android 15 that might affect your apps regardless of your app's targetSdkVersion and the areas where you should test. Focus on testing for these behavior changes first.
  • The targeted behavior changes page describes the updates in Android 15 that might affect your apps after you switch your app's targetSdkVersion to target Android 15.
  • The new features page contains an overview of new features, capabilities, and APIs, with developer guides on key new features.
  • The release notes page lists and describes known issues and transitive changes that are specific to each preview or beta release.

API Reference and diff report

The full Preview API reference is available online. While the new APIs are under development, they'll be watermarked for visibility and show "VanillaIceCream" as the API level. Note that you can only use these APIs if you are building with the Android 15 Preview SDK.

When Android 15 reaches Platform Stability and the final SDK is available, the API reference will show that the new APIs were added in the official API level.

For a detailed view of new, modified, deprecated, and removed APIs in each release, we recommend starting with the diff reports:
