Android Studio 3.3 Canary 13 available

Android Studio 3.3 Canary 13 is now available in the Canary and Dev channels.

If you have Android Studio set to receive updates on the Canary or Dev channel, you can get the update by choosing Help > Check for Updates (Android Studio > Check for Updates on Mac). Otherwise, you can download it here.

This update includes the following new features and changes in behavior:

• You can now enable full mode in R8, which provides more aggressive code shrinking than the current default behavior. To enable full mode, add the following to gradle.properties:

  android.enableR8.fullMode=true

• META-INF/proguard/* paths are now excluded from APKs/AABs.
• The Android Gradle plugin now uses SDK Build Tools version 28.0.3 by default.

• Better debug info for obsolete API: When the Android Gradle plugin warns you that you're using API that's no longer supported, it can now provide more detailed information to help you determine where that API is being used. To see the additional info, you need to include the following in your project's gradle.properties file:

  android.debug.obsoleteApi=true

  You can also enable the flag by passing -Pandroid.debug.obsoleteApi=true from the command line.

This update includes fixes for several bugs, including the following:

• Android Gradle plugin can once again run an androidMockableJar task.
• PrepareLintJar.getLintChecks() is now properly tagged with @Classpath
• Android Studio wasn't properly displaying previews for adaptive icons.
• Translation Editor was displaying columns incorrectly.
