DESCRIBE THE ISSUE IN DETAIL:

I'm seeing the below warning message every time I build our project:

Unable to strip the following libraries, packaging them as they are: libbroadcastcore.so, libcrashlytics-common.so, libcrashlytics-handler.so, libcrashlytics-trampoline.so, libcrashlytics.so.

Where libbroadcastcore.so is ours, and the rest is Firebase Crashlytics.

STEPS TO REPRODUCE:
1. Assemble our project's "release from source" build flavor which is supposed to strip .so's
2. Observe the warning message
3. Check the size of libbroadcast.so in the application's apk file and it's not stripped - about 250 megabytes

More info:

Our project structure is like this:

There is Android Library project called "broadcast" which contains native code and produces "libbroadcastcore.so".

The same Gradle project contains an Android Application as well, which depends on the "broadcast" project.

There is a product flavor called "Stages" and a build variant called "releaseFromSource" where the application project depends on the "broadcast" library project.

The .so in the library project is properly stripped: its size is about 12 MB under "stripped_native_libs".

But when libbroadcast.so is pulled into the application project, it's not stripped - I get the message above - and it size remains about 250 megabytes.

This can be seen under "build/intermediates/stripped_native_libs" in both projects (the android library and the android application which uses it).

Other .so's under the application's "stripped_native_libs":

739K Jul 16 12:24 libcrashlytics-common.so
182K Jul 16 12:24 libcrashlytics-handler.so
191K Jul 16 12:24 libcrashlytics.so
9.4K Jul 16 12:24 libcrashlytics-trampoline.so

I'm not sure if these are indeed stripped or not.

I'm just concerned about Android tools not being able to strip our own libbroadcast.so.
