bitmap - Load image from url in notification Android

Question

In my android application, i want to set Notification icons dynamically which will be loaded from URL. For that, i have used setLargeIcon property of NotificationBuilder in receiver.I reffered many link and tried various solutions but couldn't get desired output. Though i downloaded that image from url and setting that bitmap in notification, it is not being displayed. Instead it displays the setSmallIcon image as large icon. I don't know where i am going wrong. Here i am posting my code. Please help me to solve this issue. Thank you.

Code:

@SuppressLint("NewApi")
public class C2DMMessageReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if ("com.google.android.c2dm.intent.RECEIVE".equals(action)) {
            Log.e("C2DM", "received message");
            final String fullName = intent.getStringExtra("message");
            final String payload1 = intent.getStringExtra("message1");
            final String payload2 = intent.getStringExtra("message2");
            final String userImage = intent.getStringExtra("userImage");

            Log.e("userImage Url :", userImage); //it shows correct url

            new sendNotification(context)
                    .execute(fullName, payload1, userImage);
        }
    }

private class sendNotification extends AsyncTask<String, Void, Bitmap> {

        Context ctx;
        String message;

        public sendNotification(Context context) {
            super();
            this.ctx = context;
        }

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

            InputStream in;
            message = params[0] + params[1];
            try {

                in = new URL(params[2]).openStream();
                Bitmap bmp = BitmapFactory.decodeStream(in);
                return bmp;

            } catch (MalformedURLException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
            return null;
        }

        @Override
        protected void onPostExecute(Bitmap result) {

            super.onPostExecute(result);
            try {
                NotificationManager notificationManager = (NotificationManager) ctx
                        .getSystemService(Context.NOTIFICATION_SERVICE);

                Intent intent = new Intent(ctx, NotificationsActivity.class);
                intent.putExtra("isFromBadge", false);


                Notification notification = new Notification.Builder(ctx)
                        .setContentTitle(
                                ctx.getResources().getString(R.string.app_name))
                        .setContentText(message)
                        .setSmallIcon(R.drawable.ic_launcher)
                        .setLargeIcon(result).build();

                // hide the notification after its selected
                notification.flags |= Notification.FLAG_AUTO_CANCEL;

                notificationManager.notify(1, notification);

            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
