Android App Bundle (AAB) is a publishing format used by developers to distribute Android applications efficiently through the Google Play Store. This format enables the Play Store to generate APK files specifically tailored to each user's device. As a result, users download only the necessary components, reducing app size and improving installation speed.

This format must include the application's compiled code and resources, which allows for the signing and generation of APK files to be deferred to the app store, reducing the initial download size of the app. The file extension used for this format is ".aab".

Google Play requires Android App Bundles for all new apps since August 2021 and for all updates to preexisting apps since November 2021. Since May 2023, Android TV requires AABs.
