I am unable to make a network call using Volley

Question

When I am making a network call using jsonObject request. I am not receiving any response. I always receive HTTP response for request=<[ ] before my URL. I have tried these l

if your app is getting completed before response then it is causing connection timeout. you must add connection timeout in volley and retry policy also.Here is an example

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


                    }
                }, new VolleyErrorListener(this, AuthController.LOGIN_ERROR)) {
            @Override
            public Map getHeaders() throws AuthFailureError {
                return new VolleyHeader().getHeaders();
            }
        };
        jsonObjectRequest.setRetryPolicy(new DefaultRetryPolicy(
                50000,
                0,
                DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
        NetworkRequestQueue.getInstance(mContext).getRequestQueue().add(jsonObjectRequest);

NetworkRequestQueue class is as follows:

public class NetworkRequestQueue {

    private static NetworkRequestQueue mInstance;
    private static Context mCtx;
    private RequestQueue mRequestQueue;
    private ImageLoader mImageLoader;


    private NetworkRequestQueue(Context context) {
        mCtx = context;
        mRequestQueue = getRequestQueue();

        mImageLoader = new ImageLoader(mRequestQueue,
                new ImageLoader.ImageCache() {
                    private final LruCache
                            cache = new LruCache(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 NetworkRequestQueue getInstance(Context context) {
        if (mInstance == null) {
            mInstance = new NetworkRequestQueue(context);
        }
        return mInstance;
    }

    public RequestQueue getRequestQueue() {
        if (mRequestQueue == null) {
            Cache cache = new DiskBasedCache(mCtx.getCacheDir(), 10 * 1024 * 1024);
            Network network = new BasicNetwork(new HurlStack());
            mRequestQueue = new RequestQueue(cache, network);
            // Don't forget to start the volley request queue
            mRequestQueue.start();
        }
        return mRequestQueue;
    }

    public ImageLoader getImageLoader() {
        return mImageLoader;
    }

}
