What is an AAB file?
An AAB file is an Android App Bundle that developers use for uploading apps to Play Store. After upload, Play Store uses a process called Dynamic Delivery to deliver optimized versions of app packages (.APK files) to user devices so they contain only the specific portions of the app that each device needs to run. With Dynamic Delivery, app install sizes can be reduced significantly on user devices.

What is an APK File?
An APK file is an app created for the Android mobile operating system. Some apps come pre-installed on Android devices, while other apps can be downloaded from Play Store. Apps downloaded from Play Store are automatically installed on your device, while those downloaded from other sources must be installed manually.

What is an APKM file?
An APKM file is an Android app bundle created for use with APKMirror Installer, an alternative Android app installer. It is similar to an .AAB file, in that it contains a number of .APK files used to install an Android app. APKM files, however, can be installed only using APKMirror Installer.

What is a XAPK file?
An XAPK file is a package used to install Android apps on mobile devices. It is similar to the standard .APK format, but may contain other assets used by the app, such as an .OBB file, which stores graphics, media files, and other app data. XAPK files are used for distributing apps on third-party Android app download websites. They are not supported by Play Store.

What is an APKS file?
An APKS file is an APK set archive generated by bundletool, a utility used for creating and managing Android App Bundles (.AAB files). The archive, which is a compressed .ZIP file, contains a set of .APK files that are split based on device characteristics such as architecture, language, screen density, and other device features. bundletool uses the files to install optimized versions of the app on devices based on the device profile.
