Install APK
An APK file, short for Android Package Kit, is the file format used by the Android operating system to distribute and install applications. It serves as a container that includes all the components necessary for an Android app to operate — such as the executable code, resources, assets, certificates, and manifest file. The APK file structure mirrors that of Java Archive (JAR) files, utilizing ZIP compression to organize all elements.
- Download the APK file to your Android device
- Tap on the file to install it.
- Tap Install.
- Follow the steps on screen.
Install XAPK
An XAPK file is essentially an Android application package that serves as a container for both APK files and additional resources required for the app's operation. Unlike a standard APK, which typically contains only the compiled code and resources to run an Android app, an XAPK file can encompass more extensive, larger assets, such as OBB files (opaque binary blobs), high-resolution graphics, media, or other data necessary for complex apps and games.
- Download the XAPK file to your Android device
- Ensure you have XAPK Loader on your device. If you don't have XAPK Loader, you can install XAPK Loader from Play Store or download XAPK Loader here.
- Open XAPK Loader, and select on the XAPK to install it.
- Tap Install.
- Follow the steps on screen.
