If you already have an Android Studio build on the Beta channel, you can get the update by clicking Help > Check for Update (or Android Studio > Check for Updates on macOS). Otherwise, you can download here.



SDK Repository source information in App Bundle/APK

  • AGP now includes information about the repository that your app’s dependencies/SDKs came from inside the App Bundle/APK. This includes the URL of the repository and its type (Maven, Ivy). Repositories with “file://…” URLs are not included in the report.

  • This information enables Google Play to identify popular libraries so those can be analyzed. The result of that analysis is used to make recommendations on libraries/versions to use and to avoid based on known issues.

  • You can opt out from including this information by setting the property “android.bundletool.includeRepositoriesInDependencyReport=false” in gradle.properties when building your App Bundle/APK.


Configuring the Build

  • Kotlin script support is still in preview

  • In Android Gradle Plugin 7.0 betas, the DSL is now registered with the new interfaces e.g. (https://developer.android.com/reference/tools/gradle-api/7.0/com/android/build/api/dsl/CommonExtension). For groovy script users this has no effect as the implementation type is used irrespective, but for kotlin script users the implementation details will no longer be visible, and scripts that depended on them will no longer compile. Some commonly used items have been added back as deprecated, but not all.



Known Issues

  • The developer preview of the newest Wear OS (API level 30) system image has the following known issues:

    • Switching watch faces via the Wear OS phone app is not available

    • On-watch Tile management is currently unavailable. In order to preview a Tile you have created in the emulator, you can either set the Tile in the Wear OS phone app or use the wear-tiles-renderer library to preview Tiles in an activity within your app (learn more).

    • Screen recording through the power menu is not working

    • Some UI elements are not localized

    • Some UI elements might not render correctly on non-round emulator configurations.

 Android Studio 4.2.1 is now available in the Stable channel.
