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 Google Play.
Because XAPK files are not standard app installer packages, they must be installed manually or installed using an XAPK installer. After downloading an XAPK file, you can install the app (the APK file stored in the package) to an Android device using XAPK Installer. If you would like to manually install the additional files, you can unzip the XAPK file (which is a standard .ZIP file) and place the extracted files in the appropriate location on your device.
A drawback to delivering apps via Google Play is that the size of the APK file must be 50MB or smaller, which forces app developers to use other files (such as OBB files) to store additional graphics and media assets. Because of this limitation, some developers make their apps available from other sites besides Google Play. The XAPK format was introduced to package the APK file and OBB file together for a seamless delivery and installation process when downloading an Android app from a non-Google Play site.
NOTE: You should verify the trustworthiness of the site you are downloading an XAPK file from because malware can be distributed through XAPK files.
