title: Android wallpaper/background dimensions
body: <p>Which are the default dimension of the Home wallpaper/background for the various Android screen configurations (small, normal and large screens with low, medium and high density)?</p>
  
  <p>Are 9-patch PNG files supported for the wallpaper? Should I be using these instead?</p>
  
  <p>I found a method in API level 5 that gives you the minimum size of the wallpaper, but I would like to support previous versions of Android as well.</p>
  
  <p>Thanks!</p>
