OBB Image Extractor

This android app can help you extract data from OBB images right on your phone. Both JOBB-generated images and ZIP archives are supported.

Originally created to help to run apps with OBB-mounting, which doesn't work on most Android VM/Container apps. Use this app to extract cache and then, modify your target app to use extracted cache, instead of mounting OBB image, to run it on a VM/Container.

How it works for (for non-zip images):

1. Target obb image is modified. App package name is replaced with extractor package name.
2. Target obb is placed in /Android/obb/... (this app's obb folder)
3. Target obb is mounted with Android's StorageManager.mountObb
4. The app copies files from mounted image to selected output folder.
