How do I get the generalized screen size?
<p><a href="http://developer.android.com/guide/practices/screens_support.html">http://developer.android.com/guide/practices/screens_support.html</a> states:</p>

<blockquote>
  <p>Terms and concepts</p>
  
  <p>Screen size Actual physical size,
  measured as the screen's diagonal. For
  simplicity, Android groups all actual
  screen sizes into four generalized
  sizes: small, normal, large, and extra
  large.</p>
</blockquote>

<p>How do I programmatically get the generalized size of the device screen?  The method or property I am looking for will return one of:  small, normal, large, and extra large.  (or const/enums that can be mapped to those)</p>

<p>Thanks.</p>
