I've been playing around with OBB files on ICS and haven't had success mounting encrypted ones. I've been able to build OBB files on my Ubuntu 10.10 box and successfully mount them in my App on the phone. However, when I encrypt them I'm not able to mount them. I haven't found much documentation on the subject of creating the files via mkobb.sh and obbtool, other then this StackOverflow<http://stackoverflow.com/questions/4524981/what-is-obbopaque-binary-blob-in-android-develop-site>post.
When I create the OBB file I do this (see this SO post<http://stackoverflow.com/questions/12101126/using-encrypted-obb-files-in-android>for more details): *sudo modprobe cryptoloop sudo modprobe twofish sudo modprobe vfat ./mkobb.sh -d /tmp/obb/ -kblahblah -o /tmp/out.obb -v obbtool a -n com.test.blah -v 1 -s 997ff9b1516a6788 /tmp/out.obb # 997ff... is the salt from the mkobb step obbtool i /temp/out.obb # verify the obb file adb push /temp/out.obb /sdcard/ * When I mount this with StorageManager<http://developer.android.com/reference/android/os/storage/StorageManager.html>I get OnObbStateChangeListener.ERROR_COULD_NOT_MOUNT as a result and vold has this error message: * E/MountService( 2004): Couldn't mount OBB file: -1* This same code (with a null password) works correctly when mounting the non-encrypted version of the OBB. I'm wondering if anyone else has this working? Since I can't find any documentation about the mkobb.sh and obbtool it's hard to know if there is something wrong in with my process of creating OBB files, if there's something in my environment that's not right, if its a bug in Android or encrypted OBBs are just not supported at this time.
