application, by not allowing users to install your application if they have a device with a screen

configuration that you have not listed. You should use it only as a last resort, when the

application absolutely does not work with all screen configurations. Instead of using this element,

"{@docRoot}guide/practices/screens_support.html">Supporting Multiple Screens</a> to

provide scalable support for multiple screens using alternative layouts and bitmaps

for different screen sizes and densities.</p>

  <p>If you want to set only a minimum screen <em>size</em> for your your application, then you

should use the <a href="{@docRoot}guide/topics/manifest/supports-screens-element.html">{@code

          {@code xxhdpi} as a valid value, but you can instead specify {@code 480}

          as the value, which is the approximate threshold for xhdpi screens.</p>
