An AAB file is an Android App Bundle. It has the .aab file extension. Google developed this format. It is a ZIP file containing code, resources, and metadata for an Android app. Developers upload AAB files to Google Play to publish their Android apps more efficiently and flexibly.
Once uploaded, Dynamic Delivery automatically creates and signs optimized APK files. AAB files cannot be installed as Android apps. Instead, developers use a tool called bundletool to generate APK files from AAB files for specific device configurations.
AAB files organize an app’s code and resources into modules. Each module is like an APK. Google encourages using this format over APKs uploaded directly. It allows more efficient and flexible Android app publishing.
