You cannot modify ui elements from a background thread. If you are running a thread use handler or runinui method if you are using asynctask. You can modify with runinui method as well as onpostExecute and onPreExecute methods of async class

hş @thehitechpanky I'am sorry i can not contrbute it. I have been working on 2 projects right now. I do not have much time actually. I suggest you to post it on stackoverflow. You can also take a look at some tutorials about asycntask, handlers, threads, runnables in android. Hope that helps. GL.
