When I run flutter build apk --split-per-abi I get 4 files in the directory flutter-apk:
- app-arm64-v8a-release.apk,
- app-armeabi-v7a-release.apk,
- app-x86_64.apk,
- app.apk.
I already know that the first three apks are due to different cpu-architectures/ instructionsets. On my android-phone I am able to install app-armeabi-v7a-release.apk and app.apk. So are they the same? Where is the difference?
