title: Different icons size for different resolutions on Android
body: <p>I'm developing an application for a Samgsung Galaxy Tab (1024x600px). In a Activity I use few icons of 128x128px and looks great.</p>
  
  <p>But I run it in a Samgsung Galaxy S (480x800) and icons are too large.</p>
  
  <p>I put same icons at 100x100px in drawable-mdpi, but now It resized both devices. I suppose this is because Tab and Galaxy S are in the same range of density.</p>
  
  <p>How can I do automatically use different icons according to SCREEN SIZE?
  I see layout-large, layout-xlarge is according to screen size, but is for layouts, not icons.</p>
  
  <p>Thanks a lot!</p>
