How to check if user have disabled sounds for notifications?

Question

In Android 7 you can long click a notification and choose to that notifications from the belonging app should be displayed without sounds.

For Android 7 we have NotificationManager.areNotificationsEnabled() to check if user have blocked the notifications for your app. How do you check if the user have just disabled the sounds for the notifications for the app?

Update: The question still stands for Android 8/O. We have a few users who complain about not hearing any sounds and then they have disabled it without knowing it and without us having a chance to check it.

Answer 1

Sounds are enabled at IMPORTANCE_DEFAULT and upwards, so you can check like this:

@RequiresApi(26)
private boolean hasSoundsEnabled(String channelId) {
    NotificationManager manager = getSystemService(NotificationManager.class);
    NotificationChannel channel = manager.getNotificationChannel(channelId);

    return channel.getImportance() >= NotificationManager.IMPORTANCE_DEFAULT;
}
