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.

Answer 1

I might be late but still wants to add this . You can disable sound using .setSound(null) on NotificationCompat.Builder builder for all OS below O.

For O version n above add channel.setSound(null,null) after creating NotificationChannel channel

All the solutions above mine is either outdated or covers some OS versions only

Answer 2

use that exact code:

NotificationChannel chan = new NotificationChannel(NOTIFICATION_CHANNEL_ID, channelName, NotificationManager.IMPORTANCE_DEFAULT);

NOTIFICATION_CHANNEL_ID --> random String.
channelName ==> random string

Answer 3

NotificationCompat.Builder.setSilent(true)

This works regardless of the Notification Channel setting. This allows you to have a channel that makes sound by default but allows you to post silent notifications if desired without making the entire channel silent.

Reference: https://developer.android.com/reference/androidx/core/app/NotificationCompat.Builder#setSilent(boolean)

Answer 4

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);

Answer 5

Remove the line to builder.setDefaults(Notification.DEFAULT_ALL);. It will not play the sound, but you may need to enable all other notification defaults if preferred
