How to install APK and XAPK (ZIP) packages
If you only have APK file - just do the step 3.
XAPK is a ZIP archive of both APK file and OBB data file for big size games bigger than 100Mb. If you do not have xapk-installer you can do the following steps:
1) if you've got XAPK file - rename it to ZIP extention.
2) Unzip it to your hard drive. Now you should have APK and OBB files.
3) Copy and install APK file to your Android device.
4) Then copy the .obb file named 'com.gameXXXXXXXX.obb' into required location:
/SDCARD/storage/emulated/0/Android/obb/com.gameXXXXXXXX/

Note: Connect your android device to computer USB port using USB cable in order to transfer .apk and .obb files.
