What is ERROR_INTERNAL

Question

I want to install a .obb file from external storage. I wrote these codes.

storageManager.mountObb(obbPath, key, new OnObbStateChangeListener() { @Override public void onObbStateChange(String path, int state) { switch (state) { case ERROR_ALREADY_MOUNTED: storageManager.unmountObb(rawPath, true, this); break; case UNMOUNTED: storageManager.mountObb(rawPath, key, this); break; case MOUNTED: File mountedDir = new File(storageManager.getMountedObbPath(path)); // do something with mountedDir break; case ERROR_COULD_NOT_MOUNT: case ERROR_INTERNAL: case ERROR_PERMISSION_DENIED: // Error occurred!! break; } } }); 

Now I am doing this, my OnObbStateChangeListener gets state = ERROR_INTERNAL (20) .

What is this error code? How to fix it?

Addition: I found this post: What causes the jobb tool to throw a FAT Full IOException? This is probably the answer. My obb file is broken.

thanks.

It looks like this constant is set in the MountService class (com.android.server package). You can see the source code here: http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/5.1.1_r1/com/android/server/MountService.java , but as you can see, there are various reasons for setting the state to ERROR_INTERNAL
