title: Why facebook game request does not showing up on recipient profile?
body: <p>I am implementing facebook functionality on my Android game. Registered app on facebook. Everything works normally.<br>
  But when I send request  open GameRequest dialog, select friends and send. On request I get success and request id. But on recipient side does not shows up any request or notification (On facebook desktop). </p>
  
  <p>What I do wrong? </p>
  
  <p>I implemented code as following. Has created requestDialog on start as document says.</p>
  
  <pre><code>    GameRequestContent content = new GameRequestContent.Builder().
              setTitle("Title").
              setMessage("Content").
              build();
      requestDialog.show(content);
  </code></pre>
