I have a file Sharing app on the Play Store. The app can transfer selected apps and .OBB files associated with them. I am testing my app for android 11 but am unable to get obb files for apps even with ALL_FILES_ACCESS.
The android documentation states the following:-
Write access to all internal storage directories, except for /Android/data/, /sdcard/Android, and most subdirectories of /sdcard/Android. This write access includes file path access.
Apps that are granted this permission still cannot access the app-specific directories that belong to other apps because these directories appear as subdirectories of Android/data/ on a storage volume.
So, in theory, I should have been able to read any file except for /Android/data directory and write to any directory outside of /Android directory except for /Android/media.
Please correct me if I am wrong. If, access to obb is not possible this way, is there any other way or is my app's feature just ruined and user cannot transfer obb files at all?
If your app holds REQUEST_INSTALL_PACKAGES permission it can access Android/obb directory.
