How can i hide badge count number when startForeground()

Question

startForeground() need to create NotificationChannel so it will show badge number 1 on Launcher icon in Oreo devices

How can i hide/disable it programmatically?

Because Galaxy S8(Oreo) display badge number 1. And Android 8.0 emulator also display dot.

This is how i am doing now. But setShowBadge(false) not works

EDIT1:

        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

        NotificationChannel tmpC = new NotificationChannel(id, "basic", NotificationManager.IMPORTANCE_MIN);
        tmpC.setShowBadge(false);

        manager.createNotificationChannel(tmpC);

        Notification notification = new NotificationCompat.Builder(this, id)
                .setChannelId(id)
                .setAutoCancel(true)
                .build();

        startForeground(getPackageName().hashCode(), notification);

Answer 1

This answer is correct, but the point is you have to remove old version of the application by hands from Android "Applications" menu and install new version with mChannel.setShowBadge(false) on the clean device to get it working. An installation over the old version (where mChannel.setShowBadge(false) was absent) will not lead to the changing of the behaviour concerned with this badge.

Answer 2

all you need to do is calling setShowBadge(false) on your NotificationChannel object.

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

// Create notification channel.
NotificationChannel channel = new NotificationChannel({channel_id}, {name}, {importance});
mChannel.setShowBadge(false); // Disable badges for this notification channel.
mNotificationManager.createNotificationChannel(mChannel);

// Create notification and use channel
Notification notification = new NotificationCompat.Builder(context, {channel_id})
         ...
         .build();

// notify
mNotificationManager.notify({notification_id}, notification)

private void createNotificationChannel() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel serviceChannel = new NotificationChannel(
                CHANNEL_ID,
                "Example Service Channel",
                NotificationManager.IMPORTANCE_MIN
        );
        serviceChannel.setVibrationPattern(new long[]{ 0 });
        serviceChannel.enableVibration(true);
        serviceChannel.enableLights(false);
        serviceChannel.setSound(null, null);
        serviceChannel.setShowBadge(false); // 
        NotificationManager manager = getSystemService(NotificationManager.class);
        manager.createNotificationChannel(serviceChannel);
    }

setShowBadge(false) it is working
