Q:

Manifest multiple screen sizes? 

How can I support all screen sizes in my manifest?  I've got:
  <supports-screens android:smallScreens="true" android:normalScreens="true" android:largeScreens="true" android:xlargeScreens="true" android:anyDensity="true" /> 

But it says xlarge is not valid.  Any ideas what is the correct way? 

A:

Try not supplying anything for screen size.  That is completely remove the <supports-screens ... /> tag.  If your application supports all screen sizes that's nice.  You might want to consider using a different layout for horizontal and vertical orientation.
