We have just released Android Studio 2.3 Beta 2 to the Canary, Dev, and Beta Channels.

New or Noteworthy Changes
  • Moved to Gradle 3.3 Stable from 3.3 RC1 in Android Studio 2.3 Beta 1 
  • If you do native development, please also update LLDB to 2.3.3614996


Fixed Issues
  • Performance Improvements in Project Sync and general Gradle integration with the IDE.
  • App Indexing
  • Lint Fixes
  • And a few General updates


Known Issues
  • Debugging: Issue 231497 - When a debug session is launched with instant run enabled, and if the application pauses at a breakpoint on the main thread, you may notice an ANR dialog pop up on the device. In beta 2, simply ignore the dialog, or press 'Wait'. The issue will disappear once you allow the main thread to continue execution, and it happens only once during application startup. We are adding a workaround for it in beta 3 and will have a full solution in the next major update of Android Studio.


We are very close to an RC build, so please continue to file bugs you are finding in the Beta releases of Android Studio.
