title: Bitmap resources depending on screen densities
body: <p>The Android documentation being the mess that it is, I have big problem understanding what sizes my icons should be for each of the densities. The ultra-lengthy article( <a href="http://developer.android.com/guide/practices/screens_support.html" rel="nofollow">http://developer.android.com/guide/practices/screens_support.html</a> ) on supporting multiple-screen doesn't provide the information. </p>
  
  <p>So I was going to just guess some sizes when I finally hit that this gem in the "providing ressources" article ( <a href="http://developer.android.com/guide/topics/resources/providing-resources.html#AlternativeResources" rel="nofollow">http://developer.android.com/guide/topics/resources/providing-resources.html#AlternativeResources</a> ) : </p>
  
  <blockquote>
    <p>There is thus a 3:4:6 scaling ratio
    between the three densities, so a 9x9
    bitmap in ldpi is 12x12 in mdpi and
    18x18 in hdpi.</p>
  </blockquote>
  
  <p>Thing is they just introduced the xhdpi density. </p>
  
  <p>So now what is the x in 3:4:6:x ??</p>
