The problem is you are only use setSmallIcon() . This icon will be displayed in status bar and as notification icon to if you do not set setLargeIcon().

Set the small icon resource, which will be used to represent the notification in the status bar. The platform template for the expanded view will draw this icon in the left, unless a large icon has also been specified, in which case the small icon will be moved to the right-hand side.

Set the LargeIcon. Use NotificationCompat.Builder instead example with Notification.Builder

Bitmap icon = BitmapFactory.decodeResource(getResources(),R.drawable.app_logo);
Notification noti = new Notification.Builder(mContext)
     .setContentTitle("Title")
     .setContentText(subject)
     .setSmallIcon(R.drawable.small_icon)
     .setLargeIcon(icon )
     .build();
