What is an APKS file? An APKS file is an APK set archive that contains a set of .APK files optimized for different Android devices, targeting specific screen sizes, CPU architectures, or language settings. APKS files are saved in a ZIP-based format, which means you can extract their contents with many standard file compression tools.

More Information Developers typically create APKS files using bundletool , an official command-line utility maintained by Google. It works with Android App Bundles ( .AAB files) to generate sets of APKs tailored for different devices. For example, developers can build an APKS file using a command like: bundletool build-apks --bundle=/path/to/app.aab --output=/path/to/app.apks They can also install the appropriate APKs from the archive onto a connected device using: bundletool install-apks --apks=app.apks NOTE: APKS files are primarily used by developers to test apps across different device configurations before publishing. Some third-party tools may also create APKS files when exporting apps, but this is less common.
