Basically, it was explained here how Facebook made their Chathead app float above other apps and that you have to run it as a service. I followed an example that makes an image icon float above everything else. Here is the code from the example. It is not an exact answer to what you want, but it should help, and you can tweak the code to what you need to have done. You started off in the right direction and i hope this will help narrow that absolute direction you need.

This should help you get started, unless you have already finished after all of this time.
