title: Android 2.2 - screen resolutions and sizes issue
body: <p>The android version is 2.2. And the apps will not support <code>drawable-xhdpi</code> with <code>drawable-xlarge</code> folder. However, i have met many issue when I am processing different screen size from different mobile.</p>
  
  <p>The first problem is that I want to know what is the situation that android will load correct image from <code>drawable-ldpi, drawable-mdpi, drawable-hdpi</code> folder? There are one image in each folder (drawable-ldpi, drawable-mdpi, drawable-hdpi).  </p>
  
  <p>(1) 240px x 150px for drawable-ldpi<br>
  (2) 320px x 200px for drawable-mdpi<br>
  (3) 480px x 300px for drawable-hdpi</p>
  
  <p>But why i cannot see correct image if the output device width screen is 480px? The output device only shown 320px width image. Not the 480px image. The issue seems that what the thing i have missing?</p>
  
  <p>Then, i renamed all drawable folder to drawable-small, drawable-normal, drawable-large. It is working that drawable-large can display 480px width image. Will it be good if i do this way?</p>
  
  <p>The second issue is that some samsung device have got different screen resolutions, i would like to know how to support these screen resolution as I want to make 800px width screen displays 800px width image, 900px width screen displays 900px width image? Any method can do different screen resolution? Many people said the folder drawable-xhdpi can solve issue that image can be auto-scaling. I cannot see any image can be auto-scaling. Maybe i have missing some steps. </p>
  
  <p>Kindly advise. </p>
  
  <p>Thanks a lot.                                 </p>
