title: Get keyboard height in Lollipop
body: <p>What did change in Lollipop about keyboard height?</p>
  
  <p>I had a method which using <code>getViewTreeObserver()</code> correctly returned the height of the keyboard on every version before Lollipop (tested on ldpi, mdpi, hdpi and xhdpi - no problems) but it seems that on Lollipop the height returned is a little bit larger that the real keyboard's height. </p>
  
  <p>On my Asus Nexus 7 I got a height with about 70 px larger than the actual height.</p>
  
  <p>Does anybody know how to get the real keyboard's height on Lollipop?</p>
