title: Facebook SDK on Android: WebDialog closing after giving authorization
body: <p>I'm creating an app for Android and I've integrated the Facebook SDK to present the users a Feed Dialog with the following code:</p>
  
  <pre><code>public void showDialog()
  {
      Bundle parameters = new Bundle();
      parameters.putString("description", "description about link");
      parameters.putString("link", "http://google.nl");
      parameters.putString("name","Name of link");
      parameters.putString("caption","describe your caption text");
      parameters.putString("picture", "https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png");
  
      WebDialog feedDialog = new WebDialog.FeedDialogBuilder(this, Session.getActiveSession(), parameters).build();
  
      feedDialog.show();
  }
  </code></pre>
  
  <p>I call this method after I've created the session:</p>
  
  <pre><code>public void onClick(View v) 
  {
      Session.StatusCallback callback = new Session.StatusCallback() 
      {
  
          @Override
          public void call(Session session, SessionState state, Exception exception) 
          {
              if(session.isOpened()) showDialog();
          }
      };
      Session.openActiveSession(this, true, callback);
  }
  </code></pre>
  
  <p>The WebDialog comes up and I can login. Then It says that I've already authorized this app but after that, the dialog closes without a warning or something. I don't know why this is the case: all the parameters seems to be ok. Can anyone help me with this and explain why the dialog disappears?</p>
