Not getting JSON POST values from volley stringRequest

AnyBody, please solve my issue. I am unable to get any POST values from volley StringRequest.What is the Problem in my code

Here is my Android Code

     StringRequest stringRequest = new StringRequest(Request.Method.POST,URL,
            new Response.Listener<String>()
            {
                @Override
                public void onResponse(String response)
                {
                    Log.d("response",response);
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error)
                {
                    Toast.makeText(PostRequestTest.this, error.toString(), Toast.LENGTH_LONG).show();
                }
            })
    {
        //getaParams function is used to send the values to the server
        @Override
        protected Map<String, String> getParams()
        {
            Map<String, String> params = new HashMap<>();
            params.put("user_name","uname");
            Log.d("parameters09876", params.toString());
            JSONObject jsonObject = new JSONObject(params);
            Log.d("jsonRequest",jsonObject.toString());
            return params;
        }
    };
    stringRequest.setRetryPolicy(new DefaultRetryPolicy(
            Config.MY_SOCKET_TIMEOUT_MS,
            DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
            DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

    CustomVolleyRequest.getInstance(this).addToRequestQueue(stringRequest);
}

And in my PHP Code, i simply Print the POST value

<?php echo $_POST['user_name']; ?>

Here is my CustomVolleyRequest

public class CustomVolleyRequest  {
private static CustomVolleyRequest customVolleyRequest;
private static Context context;
private RequestQueue requestQueue;
private ImageLoader imageLoader;
private CustomVolleyRequest(Context context) {
    this.context = context  ;
    this.requestQueue = getRequestQueue();
    imageLoader = new ImageLoader(requestQueue,
            new ImageLoader.ImageCache() {
                private final LruCache<String, Bitmap>
                        cache = new LruCache<String, Bitmap>(20);
                @Override
                public Bitmap getBitmap(String url) {
                    return cache.get(url);
                }
                @Override
                public void putBitmap(String url, Bitmap bitmap) {
                    cache.put(url, bitmap);
                }
            });
}
public static synchronized CustomVolleyRequest getInstance(Context context) {
    if (customVolleyRequest == null) {
        customVolleyRequest = new CustomVolleyRequest(context);
    }
    return customVolleyRequest;
}
public RequestQueue getRequestQueue() {
    if (requestQueue == null) {
        Cache cache = new DiskBasedCache(context.getCacheDir(), 10 * 1024 * 1024);
        Network network = new BasicNetwork(new HurlStack());
        requestQueue = new RequestQueue(cache, network);
        requestQueue.start();
    }
    return requestQueue;
}
public <T> void addToRequestQueue(Request<T> req)
{
    getRequestQueue().add(req);
}
public ImageLoader getImageLoader()
{
    return imageLoader;
}

}

I give one suggestion to you. use JsonObjectRequest instead of using StringRequest.

StringRequest: Specify a URL and receive a raw string in response.

JsonObjectRequest and JsonArrayRequest (both subclasses of JsonRequest). Specify a URL and get a JSON object or array (respectively) in response.

TextView mTxtDisplay;
ImageView mImageView;
mTxtDisplay = (TextView) findViewById(R.id.txtDisplay);
String url = "http://my-json-feed";

JsonObjectRequest jsObjRequest = new JsonObjectRequest
    (Request.Method.GET, url, null, new Response.Listener<JSONObject>() {

@Override
public void onResponse(JSONObject response) {
    mTxtDisplay.setText("Response: " + response.toString());
}
}, new Response.ErrorListener() {

@Override
public void onErrorResponse(VolleyError error) {
    // TODO Auto-generated method stub

}
});

// Access the RequestQueue through your singleton class.
MySingleton.getInstance(this).addToRequestQueue(jsObjRequest);

See this docs
