title: Androids Facebook SDK, single sign on question?
body: <p>On Androids Facebook SDK there is a single login feature which I can't get to work.
  Done all the key hash thing but maybe there is something wrong with this method.
  What exactly should I pass on, or could somebody explain what this is supposed to do?</p>
  
  <p><code>@Override</p>
  
  <p>protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  facebook.authorizeCallback(requestCode, resultCode, data);
  }</code></p>
