Refer this link first - json

Try this - First download json parser .jar file and import it into your project.

JSONObject data = new JSONObject(data);
JSONObject menu = data.getJSONObject("menu");

For getting a String value of a field, use the following code -

String id = menu.getString("id");
JSONObject menuitem = json.getJSONObject("menuitem");

and so on.
