title: Is it possible attach a widget to the Android background?
body: <p>I was wondering if is it possible attach a widget to the main Android background/wallpaper/desktop?</p>
  
  <p>I want develop something like a clock, actually It's a very simple widget that have three buttons. This is quite different from another desktop-widgets-like, all the widgets that I've seen are like a customization of the Android wallpaper, or a customization of the Android unlocker, but this is rather different.</p>
  
  <p>If it is possible, do you know some sample code source?</p>
