title: Android Facebook SDK 3.5 request works only with both "Bundle" and on "graphPath" param
body: <p>It's my fist post here, so please, go easy :)</p>
  
  <p>I'm integrating Facebook SDK in an Android application. After the user logs in, I want to show him the app's last post in facebook, so I'm triYng to get it with(as graph object):</p>
  
  <pre><code>Bundle params = new Bundle();
  params.putInt("limit", 1);
  
  Request request = new Request(session, inRequestId + "/posts/?limit=1&amp;access_token=" +
  session.getAccessToken().toString(), params, HttpMethod.GET, new Request.Callback() {
      @Override
      public void onCompleted(Response response) {
          if(response != null){
              if(response.getError() != null)
                  Toast.makeText(getActivity(), "Error retrieveng last post", Toast.LENGTH_SHORT).show();
          else {
                  updateFacebookView( response.getGraphObject().getInnerJSONObject() );
          }
      }
      }
  });
  request.executeAsync();
  </code></pre>
  
  <p>This works, fine I think, but if I'm triyng to make it without graphPath's limit=1 parameter (inRequestId + "/posts/?access_token=" + session.getAccessToken().toString()), it has no limit, and if I don't put bundle param "limit", (as string or as int tested), it gives me this error:</p>
