title: When does surfaceDestroyed() occur
body: <p>I'm having trouble figuring out when <code>surfaceDestroyed()</code> occurs. I am trying to make my threads stop running in the <code>surfaceDestroyed()</code> method (of a SurfaceView) but it appears that my surface is never actually destroyed...can someone tell me when this happens? Or how to trigger it?</p>
