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 Google Play.
