Volley JsonObjectRequest Post request not working

问题:

I am using android Volley for making a request. So I use this code. I don't understand one thing. I check in my server that params is always null. I consider that getParams() not working. What should I do to solve this issue.

 RequestQueue queue = MyVolley.getRequestQueue();         JsonObjectRequest jsObjRequest = new JsonObjectRequest(Request.Method.POST,SPHERE_URL,null,                 new Response.Listener() {                     @Override                     public void onResponse(JSONObject response) {                         System.out.println(response);                         hideProgressDialog();                     }                 },                 new Response.ErrorListener() {                     @Override                     public void onErrorResponse(VolleyError error) {                       hideProgressDialog();                     }                 }) {             protected Map getParams() throws AuthFailureError {                 Map params = new HashMap();                 params.put("id","1");                 params.put("name", "myname");                 return params;             };         };         queue.add(jsObjRequest);,>,>,>

try to use this helper class
