Ok, so what you have to know is that support-screens doesn't make your application look 'nice' on screens you are supporting (check this link). It just tells that users with such screens will be able to download your application, but it's up to you to make it display properly. You have to create layouts for specific screens on your own.

More about it you can read in Android's documentation: http://developer.android.com/guide/practices/screens_support.html

Basically, you have to properly name your directories in which layout files are stored in order to let Android know which one should it pick up for specific device. If for example your layout's file was "layout.xml" you should have:

  /res/layout/layout.xml         // Default layout
  /res/layout-small/layout.xml   // Small screens
  /res/layout-large/layout.xml   // Large screens
  /res/layout-xlarge/layout.xml  // Extra large screens

You can go even further and make also different layouts for portrait and landscape views by specyfing another keyword in directory's name:

  /res/layout-small-land/layout.xml      // Small screens, landscape view
  /res/layout-small-portrait/layout.xml  // Small screens, portrait view

Remember that tags order is important, so you can't write layout-portrait-small.

And last add this code to your AndroidManifest file:

 <supports-screens 
 android:resizeable="true"
 android:smallScreens="true" 
 android:largeScreens="true"
 android:xlargeScreens="true"  
 android:normalScreens="true" 
 android:anyDensity="true"
