AAB may directly suggest smaller app file sizes once they are replaced from their present Android APKs, but may also give Google more control.
Google is seemingly making a major shift in terms of file formats of apps on Android. While apps have so far worked in the APK file format (standing for Android Package), Google has now officially announced that all apps will now be moved to the AAB file format – which stands for Android App Bundle. The change is one that developers may appreciate in terms of how this will affect apps – reports state that all apps on Google’s Android ecosystem can now be smaller in file size by up to 15 percent. It is this that can be the biggest impact for users right now – having large apps downloadable at much smaller file sizes can be great for users who are still on limited data networks.
