Those are nice general pearls of wisdom, but I still don't know how to fix the problem.
I have a thread updating the physics, and the foreground image will change accordingly. I also have another thread drawing onto the surfaceview. At the moment it seems highly inefficient as I'm drawing in addition the the updated foreground, the same constant background on to the canvas every step of the animation. I cannot put the background image into another view because either it will block the surfaceview or be blocked by it. Do I have to live with this, or there's a better way?
