How to show a notification without a sound java

Question

How can I make a notification that doesn't make a sound when I build it? I am building a notification, and my users don't like the fact that it makes a sound.

How can I change it to a silent one / no sound at all?

How I show notification:

android.support.v7.app.NotificationCompat.Builder builder = new android.support.v7.app.NotificationCompat.Builder(main); builder.setStyle(new android.support.v7.app.NotificationCompat.BigTextStyle().bigText(text)); builder.setSmallIcon(R.drawable.app); builder.setContentTitle("Rooster Maandag:"); builder.setOngoing(false); builder.setAutoCancel(true); builder.setSilent(true); builder.setDefaults(Notification.DEFAULT_ALL); builder.setVisibility(NotificationCompat.VISIBILITY_PUBLIC); builder.setPriority(NotificationCompat.PRIORITY_DEFAULT); notificationManager = (NotificationManager) main.getSystemService(main.NOTIFICATION_SERVICE); notificationManager.notify(NOTIFICATION_ID, builder.build()); 

I tried to search on google, but the only results I get is HOW to play a sound, not HOW to not play a sound...

Edit It possibly is a duplicate in some people's eyes, but in mine I could not find out an alternative for the there specified default, while this new method is called setDefaults

Answer 1

To disable the sound in OREO 8.1, change the priority of the notification as LOW and it will disable the sound of notification:

NotificationManager.IMPORTANCE_LOW 

The code is like:

NotificationChannel chan1 = new NotificationChannel("default", "default", NotificationManager.IMPORTANCE_LOW);

It works for me in Android Oreo.

You should just write your channel like this:

NotificationChannel notificationChannel = new NotificationChannel("Id" , "Name", NotificationManager.IMPORTANCE_DEFAULT);             notificationChannel.setSound(null, null);             notificationChannel.setShowBadge(false);             notificationManager.createNotificationChannel(notificationChannel);
