title: GraphRequest not returning details even when the Access Token is passed
body: <p>I am trying to get user details by using Facebook Graph API, but i am not getting the result which was expected. To make my self more clear i am stating the steps that i have followed.</p>
  
  <ol>
  <li>Integrated Facebook API with the Android App.</li>
  <li>Set Permission for the details that are needed.</li>
  <li>Requesting for token.</li>
  <li>After Receiving the token again requesting for details using GraphRequest.
  But the onCompleted Method in GraphRequest is not getting invoked.</li>
  </ol>
  
  <p>Here is my code snippet.</p>
  
  <pre><code>LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback&lt;LoginResult&gt;() {
          @Override
          public void onSuccess(LoginResult loginResult) {
              Toast.makeText(LoginActivity.this, loginResult.getAccessToken().toString(), Toast.LENGTH_LONG).show();
              Log.d("test", loginResult.getAccessToken().toString());
              GraphRequest graphRequest = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
                  @Override
                  public void onCompleted(JSONObject object, GraphResponse response) {
                      Log.d("response", response.toString());
                  }
              });
          }
    }
  </code></pre>
  
  <p>The Log which is with the key "response" id not getting printed, in clear the GrapRequest is not invoking the method onComplete.
  Thanks in Advance.</p>
