title: Having an issue with the camera and a live wallpaper on Nexus One devices
body: <p>Alright so I'm having an issue with my live wallpaper i've created, but I've only found this issue to occur on a stock nexus one running 2.3.3 using the stock launcher. This works great on the rest of the devices i've tested on: Moto Droid 2.3.3, Nexus S 2.3.4, HTC MyTouch 4G 2.3.3, and i've only had reports of crashes on nexus ones.</p>
  
  <p>The live wallpaper displays a preview of your camera on your wallpaper. After click set wallpaper you the stack trace below prints. You can see it sets up the camera and starts the preview, but then immediately calls to onDestroy and then force closes due the the errors after that. The screen is black this entire time. (This is once they choose set wallpaper, I'm not doing anything on the little wallpaper preview screen).</p>
  
  <p>Any clue what's happening? Not a single stack trace dips into my code. So i'm not sure where to look. And I've tried to debug it but it won't ever trigger a single one of my breakpoints, even the ones in the code it seems to be hitting and printing my logs from?</p>
