You can use gson library : https://code.google.com/p/google-gson/ — Piotr Golinski, Apr 14 '15 at 12:09

For the array objects use JSONArray. Method arr.length() returns elements count, arr.get<type>(position) or just arr.get(position) for getting element.

you may use: import org.json.JSONException; import org.json.JSONObject;

in the following way:

try {
    JSONObject myObj = new JSONObject("your json string");
} catch (JSONException e) {
                        e.printStackTrace();
                    }
