I understand how to read a plain OBB file. However, there doesn't seem to be any APIs in the library to pass in a key for cases in which the file is encrypted.

Does the APK Expansion Zip Library simply not support the opening of encrypted OBB files? If so, do I have no choice but to use the StorageManager?

Seems no one who has a solution for this :( – anhnt Aug 10 '15 at 21:34
@anhnt Nope. The developers of the library completely forgot about encryption. I ended up using the StorageManager. It's almost as easy to use anyway. – AxiomaticNexus Aug 10 '15 at 22:19
How did you resolve this issue? Can we read obb file with encrypted key? Currently I'm mounting obb file without key – anhnt Aug 10 '15 at 22:26
@anhnt I just used [storage manager's mount method](http://developer.android.com/reference/android/os/storage/StorageManager.html). – AxiomaticNexus Aug 11 '15 at 01:26
did you create obb file with JOBB tool? I didnt have a chance to make storage manager work – anhnt Aug 11 '15 at 03:28
Yes. I used the JOBB tool. – AxiomaticNexus Aug 11 '15 at 06:22
