Introduction
If you download Android games or apps from APKMODJOY, you may see different package formats such as APK, OBB, or XAPK. These files are commonly used for games with large resources or apps that require additional data.
In this guide, you will learn how to install APK files on Android, how to move OBB files into the correct folder, and how to handle XAPK packages properly. Follow the instructions below carefully to avoid installation errors.
How to Install APK on Android
APK is the standard Android installation format. Most apps can be installed directly by opening the APK file on your device.
Download the APK file
Save the APK file to your Android phone or tablet storage.
Allow installation from unknown sources
If Android blocks the installation, go to the settings page and allow your browser or file manager to install unknown apps.
Tap Install
Open the APK file and tap Install. Wait for the installation process to finish.
How to Install OBB on Android
OBB files usually contain extra game data such as graphics, sound, maps, or other large resources.
Download both APK and OBB files
Some Android games require both the APK installer and a separate OBB data package.
Install the APK first
Install the APK file before copying the OBB folder, but do not open the game yet.
Extract the OBB archive
Use ZArchiver or another file manager app to extract the OBB zip or rar file.
Move the folder to Android/obb
Copy the extracted data folder into:
Android/obb/
Launch the game
After the OBB data is placed correctly, open the game and let it load normally.
How to Install XAPK on Android
XAPK is a bundled format that often includes the APK installer together with OBB or other additional data files.
Download the XAPK file
Save the XAPK package to your device storage.
Extract the XAPK file
You can rename the file from .xapk to .zip and then extract it manually.
Install the APK inside
After extracting the package, find the APK file and install it first.
Move OBB data if included
If the extracted folder contains OBB data, move it to Android/obb/.
Open the game or app
Once everything is installed and moved correctly, launch the app or game.
Common Installation Errors and Fixes
App not installed
Check Android compatibility, remove old conflicting versions, and make sure the file is not corrupted.
OBB not detected
Make sure the extracted folder name is correct and copied to Android/obb/.
XAPK won’t open
Rename the file to ZIP and extract it manually, or use a trusted XAPK installer.
Game crashes on launch
Try reinstalling the APK, re-copying the OBB data, and checking whether the game needs a newer Android version.
Important Notes Before Installation
- Make sure your Android device has enough free storage space.
- Always download files from trusted sources.
- Use a reliable file manager such as ZArchiver to extract archives.
- Do not delete OBB data after installation if the game still needs it.
- Some apps may require permissions before running correctly.
