title: Getting black screenshot by using android screenshot library
body: <p>I'm using the Android Screenshot Library (ASL) trying to capture screenshots.
  Currently I'm running ASL in asl-native, included in ASL 1.2. </p>
  
  <p>When I press the "get screenshot"-button in my app it's telling me that the screen is successfully captured, but when I check the gallery all that it has captured is a black screen.</p>
  
  <p>I've downloaded the Android Screenshot Library from <a href="http://code.google.com/p/android-screenshot-library/downloads/list" rel="nofollow">here</a></p>
  
  <p>Does anyone know what might be the problem?</p>
