App Bundles

Android App Bundles (AAB) are the publishing format for Google Play that enables smaller, more optimized app downloads. Google generates optimized APKs from your bundle for each device.

App Bundles (AAB) are now required for Google Play submissions. They let Google optimize your app delivery by generating device-specific APKs that include only the code and resources needed for each user's device.

Benefits include smaller download sizes (typically 15-20% smaller than universal APKs), faster downloads, and lower uninstall rates. Smaller apps convert better because users are more willing to download them, especially in markets with limited data plans.
