title: Google Drive SDK for Android NotePad sample
body: <p>Does anyone manage to get Google Drive Notepad sample for Android to work? I followed the instructions as given in Google's developer page but I could not get the notification to start the Google Play Service dialog for authorization.</p>
  
  <p>The app starts as expected and when the method </p>
  
  <pre><code>credential.getToken();
  </code></pre>
  
  <p>is called, a <code>UserRecoverableAuthException</code> exception is raised. I expect that an authorization dialog will be shown, but nothing happens. I bring down the list of notification from the status bar, tap on the notification created by this app, and again nothing happens.</p>
  
  <p>When I tap on the "Recent Apps" button, I could see "Google Play services" in the list, but it has empty (blank and black) content. Tapping it does nothing, except I was brought back to my home screen.</p>
  
  <p>Any idea on this?</p>
  
  <p>I tried the other sample app, "Quick Start Drive" and this one worked as expected. An authorization dialog was presented as I expected.</p>
  
  <p>Further information, target device is Nexus 7 running OS 4.2.2.</p>
  
  <p>Many thanks.</p>
