title: Supporting all Android tablets resolutions
body: <p>The designer of our company wants me to give him the resolutions of Android tablets so he will start designing a new app.</p>
  
  <p>I know there are a lot of different resolutions (listed here: <a href="http://en.wikipedia.org/wiki/Comparison_of_Android_devices#Tablet_computers" rel="nofollow">Android Tablets computers</a>).
  I also know about the division of Android to the different dpi's (ldpi, mdpi, ...).</p>
  
  <p><strong>My questions</strong> :</p>
  
  <ol>
  <li>What should I tell the designer? He obviously not supposed to make a version for each resolution. Besides, some of the resolutions listed in the link above are in the same dpi, so which one should I choose?</li>
  <li>Considering the fact the app is going to run only on tablets, what are the dpi classes I should use? Only hdpi and xhdpi? Or should I still use all 4 classes and limit the <code>&lt;supports-screens&gt;</code> tag in the manifest?</li>
  <li>Is there a resolution that represent each of the dpi classes that I
  should stick to?</li>
  <li>I've done some reading about 9-patch. What's the point of using it if I still need to deliver a version for each dpi??</li>
  </ol>
  
  <p>Thanks in advance!</p>
