Android Volley - Making Post request

Volley.java

// Tag used to cancel the request
String tag_json_object = "json_obj_request";

String url = "http://velmm.com/apis/volley_array.json";

JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Method.POST,
        url, null,
        new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject response) {
                Log.d(TAG, response.toString());
            }
        }, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
        Log.d(TAG, error.toString());
    }
}) {
    @Override
    protected Map<String, String> getParams() {
        Map<String, String> params = new HashMap<String, String>();
        params.put("name", "Velmm.com");
        params.put("password", "*******");
        return params;
    }
};

// Adding request to request queue
AppController.getInstance().addToRequestQueue(jsonObjectRequest, tag_json_object);
