                      Response.Listener responseListener, Response.ErrorListener errorListener) {

    super(requestMethod, url, errorListener);
    this.params = params;

@Override
public Map getParams() throws AuthFailureError {
         return params;

@Override
protected Response parseNetworkResponse(NetworkResponse response) {
    try {
        String jsonString = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
        return Response.success(new JSONObject(jsonString),

    } catch (JSONException je) {
