AAB
AAB (Android App Bundle) is the current standard way of packaging mobile apps for Android phones and tablets. It's like a smart container that holds all the parts of an app, making it smaller and more efficient when users download it from the Google Play Store. Before AAB, developers used APK files, which you can think of as the older way of packaging apps. The main benefit of AAB is that each user only gets the parts of the app they actually need for their specific phone, instead of getting everything at once. This means faster downloads and less storage space used on phones.
