DESCRIBE THE ISSUE IN DETAIL:

When AGP builds the app module and tries to bundle native libraries (*.so), it fails to strip debug symbols so the final aab/apk contains large native library files with debug symbols.

Minimal setup:

• There are two modules; 1 native library module + 1 app module
• ndkVersion is not specified in the build.gradle of the app module.
  • => Specifying ndkVersion can be used as a workaround
• (maybe) None of NDK are not installed to the machine (like clean CI env or Docker container)

STEPS TO REPRODUCE:

1. Clone the following repository; https://github.com/h6ah4i/gradle-ndk-strip-debug-symbol-not-applied-bug

2. Build a Docker image with docker-compose.

   cd [CLONED REPOSITORY DIR]
   docker-compose build
   

3. Check warning messages displayed when ndkVesion is NOT specified in the app module.

   $ docker-compose run build_env bash -c "./gradlew clean && ./gradlew assembleRelease"

4. Check the issue is gone when ndkVesion is specified in the app module. (testing the workaround)

   $ docker-compose run build_env bash -c "./gradlew clean && SET_NDK_VERSION_IN_APP_MODULE=1 ./gradlew assembleRelease"
