What are .APK and .XAPK files?

What is an .APK file?

An Android package (APK) is a package file format used by the Android operating system to distribute and install mobile applications and middleware. An APK file is an archive file, specifically a package of type zip format, based on the JAR file format, with .apk as the file extension.

What is a .XAPK file?

An XAPK is a standard zip format that contains Android App Bundles or installation packages (.apk), OBBs, cache assertions, and other data files to ensure an application downloads to Android and runs successfully. The Google Play Store has restrictions on app file size, so for apps over 100MB, developers can use the XAPK file format to let users download APK files on Android without corruption. There are now two types of .XAPK files as shown below.

  1. Google Play hosts expansion files for your app and provides them to devices for free. Expansion files can be in any format of your choice (ZIP, PDF, MP4, etc.), and they usually contain other resources your application needs.

For simplicity, XAPK = APK + OBB data + Cache + App Icon and Miscellaneous Info.

  1. Another XAPK file format consists of the Android App Bundle, which is used to generate and serve an optimized APK for each user's device configuration. Each APK is a complete and self-contained version of an application, but they share the same application and package name, and are signed with the same release key. This new XAPK file upload format allows users to get smaller, more optimized downloads because they only download the code and resources needed to run the application.
