Ok that's weird.
If you have nothing in your onStart and your onResume sets the loop as
running for your drawing loop, then that is where you should have a
look.
My guess would be that the restarting of your looping via setRunning
doesn't do what you think and that it is just not restarting at all so
that you don't have any drawing going on.
Or maybe you are creating objects in your onCreate method that get
destroyed when your apps looses focus and that are never recreated
again because onCreate is only called the very first time you launch
your activity.
First thing would be to Log.e("drawing","I'm drawing") in your thread
drawing loop.
