Volley JsonObjectRequest Post request not working

Question

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<JSONObject>() {                     @Override                     public void onResponse(JSONObject response) {                         System.out.println(response);                         hideProgressDialog();                     }                 },                 new Response.ErrorListener() {                     @Override                     public void onErrorResponse(VolleyError error) {                       hideProgressDialog();                     }                 }) {             protected Map<String, String> getParams() throws AuthFailureError {                 Map<String, String> params = new HashMap<String, String>();                 params.put("id","1");                 params.put("name", "myname");                 return params;             };         };         queue.add(jsObjRequest);

try to use this helper class

import java.io.UnsupportedEncodingException; import java.util.Map;     import org.json.JSONException; import org.json.JSONObject;     import com.android.volley.NetworkResponse; import com.android.volley.ParseError; import com.android.volley.Request; import com.android.volley.Response; import com.android.volley.Response.ErrorListener; import com.android.volley.Response.Listener; import com.android.volley.toolbox.HttpHeaderParser;  public class CustomRequest extends Request<JSONObject> {      private Listener<JSONObject> listener;     private Map<String, String> params;      public CustomRequest(String url, Map<String, String> params,             Listener<JSONObject> reponseListener, ErrorListener errorListener) {         super(Method.GET, url, errorListener);         this.listener = reponseListener;         this.params = params;     }      public CustomRequest(int method, String url, Map<String, String> params,             Listener<JSONObject> reponseListener, ErrorListener errorListener) {         super(method, url, errorListener);         this.listener = reponseListener;         this.params = params;     }      protected Map<String, String> getParams()             throws com.android.volley.AuthFailureError {         return params;     };      @Override     protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {         try {             String jsonString = new String(response.data,                     HttpHeaderParser.parseCharset(response.headers));             return Response.success(new JSONObject(jsonString),                     HttpHeaderParser.parseCacheHeaders(response));         } catch (UnsupportedEncodingException e) {             return Response.error(new ParseError(e));         } catch (JSONException je) {             return Response.error(new ParseError(je));         }     }      @Override     protected void deliverResponse(JSONObject response) {         // TODO Auto-generated method stub         listener.onResponse(response);     } } 

In activity/fragment do use this

RequestQueue requestQueue = Volley.newRequestQueue(getActivity()); CustomRequest jsObjRequest = new CustomRequest(Method.POST, url, params, this.createRequestSuccessListener(), this.createRequestErrorListener());  requestQueue.add(jsObjRequest);
