title: Release bitmaps from android.view.GLES20DisplayList
body: <p>Is anyone knows how to Release bitmaps from android.view.GLES20DisplayList.
  And why it keeps them alive even if you clean, let's say, ImageView manually?
  Or maybe there is a way to disable GLES20DisplayList, tried to use android:hardwareAccelerated="false" in AndroidManifest, still no luck.</p>
  
  <p>Looks like affected only in 4.2(1)</p>
  
  <p><strong>update:</strong> looks like you can't disable hardware acceleration on 4.2.1 (bug?)</p>
  
  <p>simple test:</p>
  
  <pre><code>Android manifest:
  application ... android:hardwareAccelerated="false"
  
  System.out.println("isHardwareAccelerated: " + mListView.isHardwareAccelerated());
  mListView.setLayerType(LAYER_TYPE_SOFTWARE, null);
  System.out.println("isHardwareAccelerated: " + mListView.isHardwareAccelerated());
  </code></pre>
  
  <p>result:</p>
  
  <pre><code>12-06 17:15:27.129: I/System.out(30752): isHardwareAccelerated: true
  12-06 17:15:27.129: I/System.out(30752): isHardwareAccelerated: true
  </code></pre>
