title: Android Wifi signal icons
body: <p>Is there a way to get the icon used by the system for the Wifi strength signal (I haven't found them anywhere..)? I want them to create a custom Wifi Manager for my application.</p>
  
  <p>It would be really useful to have also the layout assets if they are available (no idea however of where I can look for taking them :( ).</p>
  
  <p>Thanks :)</p>
