Improved resource shrinker
Support for apps with dynamic features
The default implementation of the Android resource shrinker has been updated in Android Gradle Plugin 7.1.0-alpha09. The new implementation supports shrinking apps with dynamic features.
Experimental further app size reductions
The new resource shrinker implementation can reduce the size of your shrunk app even more by modifying the resource table to remove unused value resources and references to unused file resources. The new resource shinker can delete unused file resources completely, reducing the size of your app more. This behavior is not enabled by default yet, but you can opt in to try it by adding the experimental option android.experimental.enableNewResourceShrinker.preciseShrinking=true to your project's gradle.properties file.
Please report any issues you find with the new resource shrinker or the experimental flag. To help diagnose issues, or as a temporary workaround, you can switch back to the previous implementation by adding android.enableNewResourceShrinker=false to your project's gradle.properties. The new shrinker replaces unused file-based resources with slightly different minimal files than the previous resource shrinker, but this is not expected to have any runtime impact.
The old implementation is scheduled to be removed in Android Gradle plugin 8.0.0.
