How to set the app icon as the notification icon in the notification drawer

Question

As shown in the figure...
I am getting my notification icon(on left to the red colour).
But I need to display the app icon as shown by the black arrow

    public void notify(View view){
    notification.setSmallIcon(R.drawable.ic_stat_name);
    notification.setTicker("Welcome to ****");
    notification.setWhen(System.currentTimeMillis());
    notification.setContentTitle("abcd");
    notification.setContentText("abcd");


    Intent intent = new Intent(this, home.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    notification.setContentIntent(pendingIntent);


    NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    nm.notify(uniqueID, notification.build());
}

Try this code at your notification builder :

NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(context)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setLargeIcon(BitmapFactory.decodeResource(context.getResources(),
                        R.mipmap.ic_launcher))
                .setContentTitle(title)
                .setContentText(message)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

android.app.NotificationManager notificationManager =
                (android.app.NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());

Set Large icon does the trick.Comment below if you have any further info
