title: Facebook apprequest messages are not displayed on receiver's notifications list
body: <p>I am trying to send a direct message to friends using Facebook Dialogs on Android. The code that does is as follows:</p>
  
  <pre><code>Bundle params = new Bundle();
      params.putString("message", "sending direct messages");
      params.putString("to", friendId);
      mFacebook.dialog(FBFriendsActivity.this, "apprequests", params, new PostDialogListener());
  </code></pre>
  
  <p>The code executes well. No error. The Facebook send dialog shows up, and I click on send. but, I do not see any notifications listed on the receiver's notifications.</p>
  
  <p>Do I have to have a facebook app in order for this to work? If so, how do I send user-to-user requests?</p>
