How to implement BigPicture style Notification:

Miracle has been done by .setStyle(new Notification.BigPictureStyle().bigPicture(result)) :

I have done this way with:

Generate notification by AsyncTask:

new generatePictureStyleNotification(this,"Title", "Message", 
                 "http://api.androidhive.info/images/sample.jpg").execute();

AsyncTask:

public class generatePictureStyleNotification extends AsyncTask {

        private Context mContext;
        private String title, message, imageUrl;

        public generatePictureStyleNotification(Context context, String title, String message, String imageUrl) {
            super();
            this.mContext = context;
            this.title = title;
            this.message = message;
            this.imageUrl = imageUrl;
        }

        @Override
        protected Bitmap doInBackground(String... params) {

            InputStream in;
            try {
                URL url = new URL(this.imageUrl);
                HttpURLConnection connection = (HttpURLConnection) url.openConnection();
                connection.setDoInput(true);
                connection.connect();
                in = connection.getInputStream();
                Bitmap myBitmap = BitmapFactory.decodeStream(in);
                return myBitmap;
            } catch (MalformedURLException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
            return null;
        }

        @TargetApi(Build.VERSION_CODES.JELLY_BEAN)
        @Override
        protected void onPostExecute(Bitmap result) {
            super.onPostExecute(result);

            Intent intent = new Intent(mContext, MyOpenableActivity.class);
            intent.putExtra("key", "value");
            PendingIntent pendingIntent = PendingIntent.getActivity(mContext, 100, intent, PendingIntent.FLAG_ONE_SHOT);

            NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
            Notification notif = new Notification.Builder(mContext)
                    .setContentIntent(pendingIntent)
                    .setContentTitle(title)
                    .setContentText(message)
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setLargeIcon(result)
                    .setStyle(new Notification.BigPictureStyle().bigPicture(result))
                    .build();
            notif.flags |= Notification.FLAG_AUTO_CANCEL;
            notificationManager.notify(1, notif);
        }
    }
