Where is cached media stored on android client?

I had a hosted instance that I was using for testing and it is now gone (I tried to renew with an my AMEX card which is not accepted, and then forgot to get back and renew with a different card). I need the media from the layout that this test player is displaying but the hosted instance now appears to be gone so my only option might be to get it from the cache on the client.

Where is the content stored on an android client?

You could contact the help desk about your CMS instance - it may well still be there (we keep them a long time).

Android stores library data in /data/data/uk.org.xibo.client/files - where the root of this folder is located depends on whether you selected a SD card or not.
