Standalone R8 Configuration Analyzer Gradle task
Android Gradle plugin 9.3 introduces a dedicated Gradle task for running the R8 Configuration Analyzer in isolation. The R8 Configuration Analyzer helps you optimize your app's code shrinking and obfuscation rules.
./gradlew :app:analyzeReleaseR8Config
The :app:analyzeReleaseR8Config task generates the report without completing
the APK or Bundle compilation pipeline. This provides a shorter feedback loop,
which speeds up developer iteration when refining keep rules. Alternatively,
you can generate the report automatically by running an R8 release build (such
as assembleRelease or bundleRelease).
For more information, see Run the standalone Gradle task for generating report.

Updated optimization DSL to configure R8 keep rules
Introduces an updated optimization DSL to configure keep rules for R8
optimization, supported by app modules and library module tests. To configure
optimization with the updated DSL, use the new optimization block. For apps,
configure the optimization block within a build type (such as release or
debug) in the app-level build script. The updated optimization DSL makes R8
configuration simpler:
- Turning on optimization enables both code optimization and optimized resource shrinking.
- You no longer need to specify the default Android keep rules file.
Note that the legacy DSL continues to be supported.
Introduction of source sets to define keep rules
Place keep rules in the src/<variant>/keepRules/ source set, with the
file-suffix .keep. Source sets for keep rules are supported by the updated
optimization DSL and the legacy DSL. Using source sets for keep rules is
supported in app modules, library modules, and as a way to define consumer rules
in Kotlin Multiplatform (KMP) modules.
