title: method get(String) is undefined for the type Object when getting location from Facebook SDK
body: <p>I have a GraphUserCallback that returns a graphObject of the requested user information, I think put this into a Map as below.</p>
  
  <pre><code>Map&lt;String, Object&gt; responseMap = new HashMap&lt;String, Object&gt;();
  GraphObject graphObject = response.getGraphObject();
  responseMap = graphObject.asMap();
  </code></pre>
  
  <p>I then grab each data item I need from the map e.g:</p>
  
  <pre><code>birthday = responseMap.get("birthday").toString();
  </code></pre>
  
  <p>This works well, apart from when I try to get the users location, the responseMap location item is actually an object containing name and id.</p>
  
  <p>So I try to do</p>
  
  <pre><code>location = responseMap.get("location").get("name").toString();
  </code></pre>
  
  <p>However I get the error:</p>
  
  <blockquote>
    <p>method get(String) is undefined for the type Object</p>
  </blockquote>
  
  <p>What can I do to get the 'name' field from the object in the 'location' of the responseMap</p>
  
  <p>I should not that the structure seems to be a JSON object as if I do </p>
  
  <pre><code>location = responseMap.get("location").toString();
  </code></pre>
  
  <p>I get what looks like a JSON</p>
