Notes

To copy files in the Android Emulator or in the real devices you can use the adb tool (with adb push and adb pull commands) or the Device File Explorer in Android Studio.

The folder that will contain the file that the app can use is /storage/self/primary.

If the release version of the application fails to install going to Google Play and disabling Play Protect should fix the problem.
