title: Are Android's DisplayMetrics xdpi and ydpi always equal?
body: <p>I've been checking the output of the DisplayMetrics 'xdpi' and 'ydpi' on several emulator screen sizes (WVGA &amp; HVGA) and I notice that these values are always equal i.e. metrics.xdpi == metrics.ydpi.</p>
  
  <p>I just wanted to confirm this with folks here? Is it true on any phone the metrics.xdpi will always be equal to the metrics.ydpi value?</p>
