Describe the bug

When building the app for release, it fails with the following error message:

> Task :app:transformClassesAndResourcesWithR8ForDevdefaultshRelease FAILED
/Users/runner/work/1/s/android/app/proguard-rules.pro:67:25: R8: Use of generics not allowed for java type.

This is because of the ProGuard rule mentioned in the quickstart guide:

-keepclassmembers class <APPLICATION ID>.BuildConfig {
   public static <fields>;
}

I could fix it by replacing <APPLICATION ID>.BuildConfig with the import path of the BuildConfig as it is in MainApplication.java.

Steps to Reproduce

Setup the Project with ProGuard and RNUC as in the Guide

Build the Project for Release:

npm run rnuc config/falvor/env.dev && cross-env BUILD_TARGET=flavor ./android/gradlew -p android clean :app:assembleFlavorRelease

It will fail

Expected behavior

It should build the app successfully.

hi @tschanz-pcv, I'm not entirely sure what is the problem? is documentation not clear enough about proguard rules? should it say <PACKAGE_NAME> instead? feel free to open PR suggesting a fix, thank you
