    List params = new ArrayList();
    JSONArray rules = null;
    JSONObject json = jsonParser.makeHttpRequest(“http://www.emrahkahraman.com.tr/mary.json”, “GET”,
    params);
    try {
    rules = json.getJSONArray(“rules”);
    int rulesCount=rules.length();
    String groupOp = json.getString(“groupOp”);
    for (int i = 0; i < rules.length(); i++) { JSONObject c = rules.getJSONObject(i); String field = c.getString("field"); String op = c.getString("op"); String data = c.getString("data"); }
