Please refer these link:

http://developer.android.com/guide/practices/screens_support.html

For Different screen size, The following is a list of resource directories in an application that provides different layout designs for different screen sizes and different bitmap drawables for small, medium, high, and extra high density screens.You still need to edit the layout resource to fit better

res/layout/my_layout.xml             // layout for normal screen size ("default")
  res/layout-small/my_layout.xml       // layout for small screen size
  res/layout-large/my_layout.xml       // layout for large screen size
  res/layout-xlarge/my_layout.xml      // layout for extra large screen size
  res/layout-xlarge-land/my_layout.xml // layout for extra large in landscape orientation

  res/drawable-mdpi/my_icon.png        // bitmap for medium density
  res/drawable-hdpi/my_icon.png        // bitmap for high density
  res/drawable-xhdpi/my_icon.png       // bitmap for extra high density

The following code in the Manifest supports all dpis.

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