How to get the resources from Android expansion file?

Is there a way to read the resources from Android expansion file (.obb)?

Hey - sorry to be a pain - am going through bumping all the questions about expansion files!
I can’t see a solution documented anywhere - did you discover anything?
Thanks
Steve

Seems to have been plenty of views to this re-post: Update from me I can now mount and access the main external OBB file - i guess this is of interest to share once I have tidied the code. Get in touch if you want to help to speed this process along.
