title: Hierarchy Viewer wants a forwarded port, how?
body: <p>I'm trying to run the Hierarchy Viewer to investigate one screen of my app on an Android device (Samsung Galaxy S4, dev edition).</p>
  
  <p>The HV starts up, but displays a blank screen in the tree view, with these error messages</p>

  [2014-06-10 16:52:23 - hierarchyviewer]Unable to get the focused window from device 86d22a7c
  </code></pre>
  
  <p>What are the steps to give HV the forwarded port that it wants?   This is on MacOS 10.7.5</p>
