title: is it possible to use Gson.fromJson() to get ArrayList<ArrayList<String>>?
body: <p>let's say i have a <code>json</code> array of arrays</p>
  
  <pre><code>String jsonString = [["John","25"],["Peter","37"]];
  </code></pre>
  
  <p>i would like to parst this into <code>ArrayList&lt;ArrayList&lt;String&gt;&gt;</code> objects. when i used</p>
  
  <p><code>Gson.fromJson(jsonString,ArrayList&lt;ArrayList&lt;String&gt;&gt;.class)</code></p>
  
  <p>it doesn't seem to work and i did a work around by using</p>
  
  <p><code>Gson.fromJson(jsonString,String[][].class)</code></p>
  
  <p>is there a better way to do this?</p>
