Galaxy Watch（Tizen）上的通知不显示图标

Question

我有简单的应用程序发送通知，我想在三星观看（Active 2）上显示。该通知本身已显示在手表上，但我无法显示图标。这是Gmail和我的应用程序的通知示例。在Gmail（左）上，您可以看到该应用的图标，而在右边，您无法看到。我想念什么？

notification-shown

我使用的相关代码如下：

    int notificationId = 001;
    Bitmap bIcon = BitmapFactory.decodeResource( getResources(),R.drawable.ic_stat_ic_notification);

    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, channelId)
            .setSmallIcon(R.drawable.ic_stat_ic_notification)
            .setLargeIcon(bIcon)
            .setContentTitle(title)
            .setContentText(message)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

    NotificationCompat.WearableExtender wearableExtender =
            new NotificationCompat.WearableExtender().setContentAction(0);

    notificationBuilder.extend(wearableExtender);

    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel channel = new NotificationChannel(channelId,
                "Home Notifier",  NotificationManager.IMPORTANCE_DEFAULT);
        notificationManager.createNotificationChannel(channel);
    }

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