I see some folks are asking about the GPL in the comments.
This app is all code I made myself. It contains no code from the XBMC project or elsewhere. Its based on the online XBMC docs and experimentation. I mailed the gentleman from the XBMC project who left the comment.

Try it in the dashboard Android device.
