So I haven't released in a while. Android Studio used to generate only one apk, which was a release version. This time it generated 3 like the following:
1.app-armeabi-v7a-release.apk
2.app-x86-release.apk
3.app-universal-release.apk
I'm going to assume that I want to use the universal one for the Google Play Store.
But can someone break down the specifics of each one?
