My app now has 3 notification channels, I want to remove 2 of them.
I thought simply not registering 2 channels would do the trick but when I open the notification settings on the Android device, the old channels still appear.
Is it possible to remove them? They have no use and can confuse the users.

推荐答案

通知频道一旦创建便会永久保留.

Notification channels stay forever once they are created.

要再次删除它们，只需调用 在NotificationManager上，并带有您要删除的频道的ID:

To remove them again, simply call deleteNotificationChannel() on the NotificationManager with the ID of the channel you want to delete:

notificationManager.deleteNotificationChannel("channel_id");
