Answer 1

Use String request instead of jsonrequest like this

            StringRequest loginMe = new StringRequest(Request.Method.GET, "http://114.35.246.42:2212/MobileApp/DEST_WebService.asmx/GetNews", new Response.Listener() {

                @Override
                public void onResponse(String response) {

                    System.out.println("LoginActivity -- onResponse --> " + response);

                    if (progressDialog != null) {

                        progressDialog.dismiss();

                    }

                    try {

                        JSONObject jsonObject = new JSONObject(response);

                    } catch (Exception e) {

                        CommonUtility.somethingWentWrongDialog(activity,
                                "LoginActivity -- onResponse-- Exception --> ".concat(e.getMessage()));

                    }
                }
            }, new Response.ErrorListener() {

                @Override
                public void onErrorResponse(VolleyError error) {

                    if (progressDialog != null) {

                        progressDialog.dismiss();

                    }

                    CommonUtility.somethingWentWrongDialog(activity,
                            "LoginActivity -- onErrorResponse --> ".concat(error.getMessage()));

                }
            }) {

                @Override
                protected Map getParams() {

                    Map params = new HashMap<>();


                    System.out.println("LoginActivity -- LoginParams --> " + params.toString());

                    return params;

                }
            };

            loginMe.setRetryPolicy(new DefaultRetryPolicy(60000, DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
                    DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

            Volley.newRequestQueue(activity).add(loginMe);
