title: Session.openActiveSession only calls OPENING in Facebook Android SDK
body: <p>I am trying to login with Facebook using the Facebook Android SDK, however, the status callback is fired only once with <code>OPENING</code> session state. After that, a Facebook login activity appears with no content (I know it's that activity as it has the title that I've set for <code>title_facebook_login</code> in strings.xml) for a brief moment and disappears within a second. No other callback is fired, no exceptions, no crashes. It just waits forever at my initial activity. Here is my code:</p>
  
  <pre><code>Session.openActiveSession(parent, true, new Session.StatusCallback() {
          @Override
          public void call(Session session, SessionState state, Exception exception) {
              if(state == SessionState.OPENED){
                  String accessToken = session.getAccessToken();
              }
          }
      });
  </code></pre>
  
  <p>Why wouldn't the callback fire for <code>SessionState.OPENED</code> (or CREATED, or even CLOSED) but only OPENING?</p>
