title: Defining sw identifiers in <supports-screens> attribute in the manifest
body: <p>I have several drawable folders in my app. Such as drawable-sw600dp-hdpi and drawable-sw480dp-mdpi, etc.  How can I define them in  attribute in the manifest file? In the developer documentation I can only see that I have to set true to large, xlarge, small, etc. But that's not exactly what I need. Because I don't want 10 inch tablets to download my app, but only 7 inch tablets. How can I do that?</p>
