Android 11 Beta 2

About Android 11 Beta 2

Android 11 Beta 2 marks the Platform Stability milestone for developers and includes the latest optimizations and bug fixes. This release is suitable for development, testing, and general use. Android 11 is still in active development, so the Android system and apps might not always work as expected.

As with previous versions, Android 11 includes behavior changes to help improve performance, battery life, security, and privacy. In some cases, these changes can affect apps until they are updated to support Android 11, so you might see impacts ranging from minor issues to more significant limitations. In general, most apps will work as expected, as will most APIs and features, but please review the known issues listed below to get a better idea of what to expect.

You can install this release on any Pixel 2, 3, 3a, or 4 device by enrolling your device to receive over-the-air updates. Other device manufacturers might also provide an Android 11 beta for their devices. Refer to your device manufacturer's website for more information.

Developers can also use the Android Emulator or use an Android Generic System Image (GSI) to aid with development and testing.

We have fixed this issue internally and it will be available to you in the next Beta release.

Known issues: Bluetooth

• In Android 11 Beta 1, the system incorrectly enforces Bluetooth privileged permission for RemoveBond.

App compatibility changes

The following changes related to app compatibility are included in Developer Preview 2:

  When running on Android 11, apps can use the new Build.Version.RELEASE_OR_CODENAME field. When apps access this field, the system returns one of the following values:

  • If the build is a final, public release: Build.Version.RELEASE
  • If the build is not a final, public release: Build.Version.CODENAME

Known issues: Android Platform

• Developers who switch their app to target Android 11 can't run instrumented tests. Although this issue has already been resolved for future developer preview releases, you can work around this issue in Developer Preview 2 using one of the following methods:

  • Install your test app as force queryable using the --force-queryable flag.
  • Mark your test app force queryable in the manifest with <application android:forceQueryable="true" />.

  • Add your test package as queryable in the target's manifest:

    <manifest .../>
      <queries>
        <package android:name="<test package>" />
      </queries>
    </manifest>
