Answer 1

if you use My Singleton try this:

MyVolley.getInstance(this).getRequestQueue().getCache().clear();

Maybe you use cache on your code

Answer 2

To provide POST parameter build a JSONObject with your POST parameters and pass that JSONObject as a 3rd parameter. JsonObjectRequest constructor accepts a JSONObject in constructor which is used in Request Body.

JSONObject paramJson = new JSONObject();

paramJson.put("key1", "value1");
paramJson.put("key2", "value2");


JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST,url,paramJson,
    new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {

        }
    },
    new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {

        }
    });
requestQueue.add(jsonObjectRequest);

Answer 3

Please override the getBody() method, and if your server can not handle JSON request parameter, you have to override the getHeaders() method to change your Content-Type.

it happened because Volley params cache.

clean it like this

requestQueue.getCache().clear();

I solved my issue by simply removing Content-Type from header :)
