I have 2 modules in my project
Moudle 1:
libs/armeabiModule 2:
libs/armeabilibs
During app installation, either armeabi or armeabi-v7a libs will be extracted from the APK. In this scenario, you would hope Android chooses the armeabi libs, but on armeabi-v7a devices, it will install armeabi-v7a libs, since at least one exists.
If you are going to include libs for multiple ABIs then you must include all libs for all those ABIs.
