  <p>When I use Canvas.drawPath method, it works fine. However, if I change to Canvas.drawVertices, it draws nothing. I have checked what is said in <a href="https://stackoverflow.com/questions/6434132/bug-in-canvas-drawvertices-with-repro-code-and-logcat">Bug in Canvas.drawVertices? (with repro code and logcat)</a> and <a href="https://stackoverflow.com/questions/10579382/method-drawvertices-didnt-drawing-anything-on-android-canvas">Method drawVertices() didn&#39;t drawing anything on Android Canvas</a>, but the result is the same in my case.</p>
  
  <p>I am using <a href="http://androvm.org/blog/download/" rel="nofollow noreferrer">AndroVM(v 4.1.1)</a> in <a href="https://www.virtualbox.org/wiki/Downloads" rel="nofollow noreferrer">VirtualBox(v 4.1.22)</a> for testing. Could it be the emulator?</p>
  
  <p>Any idea?</p>
