title: sendUserActionEvent() is null
body: <p>I've got a real doozy here.  When I click on spinners, open menu items, or open context menus on long-clicks I get the same Logcat message:</p>
  
  <pre><code>08-02 21:20:57.264: E/ViewRootImpl(31835): sendUserActionEvent() mView == null
  </code></pre>
  
  <p>The tag is <code>ViewRootImpl</code>, and the message is <code>sendUserActionEvent() mView == null</code>.  I could not find anything helpful about this on the web.  I searched through the Android sources and found some references to <code>mView</code>, but I could not find the file in which this log message is printed.  For reference, I'm using a Samsung Galaxy S4 running 4.2.2, or API 17.  The same message does NOT occur when debugging on a Nexus 7 running Android 4.3.  Any ideas?  Is this a Samsung-specific issue?</p>
