title: Android background image resolutions
body: <p>I'm currently sizing a background for an android application, I want to know, what resolutions should I supply for low, medium and high density screens?</p>
  
  <p>I can't make a decision, as the documentation seems to refer to the density, which depends on the resolution and the physical size of the screen, while I really want an image that is scaled as little as possible to minimize resource the footprint.</p>
  
  <p>Many thanks</p>
