Android : Android send post request using volley and receive in php

am trying to use volley in my project to handle all my Http request since its the most efficient one as far as I know. So I started to learn volley by following AndroidHive Tutorial

My first GET Request was successful. Then I moved on to post request and I failed. I saw on SO as well many people had problems combining post request of volley with php. I believe we cannot access it using the normal way that is $_POST[""] as volley sends a json object to the url which we specify.

There where lots of solution which I tried but dint succeed. Iguess there should be a simple and standard way of using volley with php

So I would like to know what do I need to do in order to receive the json object sent by volley in my php code.

And also how do I check if volley is really sending a json object.

Hoping to find some help.

My volley code to send simple post request:

JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.POST,
                url, null,
                new Response.Listener<JSONObject>() {

                    @Override
                    public void onResponse(JSONObject response) {
                        Log.d(TAG, response.toString());
                        pDialog.hide();
                    }
                }, new Response.ErrorListener() {

                    @Override
                    public void onErrorResponse(VolleyError error) {
                        VolleyLog.d(TAG, "Error: " + error.getMessage());
                        pDialog.hide();
                    }
                }) {

            @Override
            protected Map<String, String> getParams() {
                Map<String, String> params = new HashMap<String, String>();
                params.put("name", "Droider");
                return params;
            }

        };

// Adding request to request queue
AppController.getInstance().addToRequestQueue(jsonObjReq, tag_json_obj);

My PHP code to receive json object: (I am pretty sure this is the wrong way, I am not that good in php)

<?php
    $jsonReceiveData = json_encode($_POST);
    echo $jsonReceivedData;
?>
