What are ABB and APK Files?

One of the two sites used for the application package in the Android application world is the APK file and the other is the ABB file.

  • apk: Android Application Package
  • .aab: Android App Bundle

If you want to test your application and install it on your phone, you must produce an APK file. The APK file can be installed on the Android phone and you can test your application. The AAB file cannot be installed on the phone.

If you want to upload your application to the Google Play Store for the first time, you must produce an ABB file. After 01.08.2021, Google Play Store announced that it will not accept APK files for first downloads and must be ABB files.
