Cannot disable notification vibration in Android 8

Question

I try to disable vibration when showing a notification.

Func:

public static Notification buildNotifForUploaderService(Context ctx, String          


        

Answer 1

This function worked for me. With it I create the notification channel in what fully disable lights, vibration and sound.

private void createNotificationChannel() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel serviceChannel = new NotificationChannel(
                CHANNEL_ID,
                "Foreground Service Channel",
                NotificationManager.IMPORTANCE_DEFAULT
        );

        serviceChannel.setVibrationPattern(new long[]{ 0 });
        serviceChannel.enableVibration(true);
        serviceChannel.enableLights(false);
        serviceChannel.setSound(null, null);

        NotificationManager manager = getSystemService(NotificationManager.class);
        manager.createNotificationChannel(serviceChannel);
    }
}

Answer 2

Like this answer, do:

mNotificationChannel.setVibrationPattern(new long[]{ 0 }); 
mNotificationChannel.enableVibration(true);

Important 1: even if I set the vibration pattern above, but set enableVibration to false, it vibrates. So, set enableVibration to true!

Important 2: like this another answer, the channel keeps its initial settings, so uninstall and install the app again to apply the changes!

Hope it helps!

Answer 3

Add this line to your code to stop vibration:

notificationChannel.enableVibration(false);
// Above line will disable your vibration for the notification

Also, remove the vibration pattern.

So, your updated code will be:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    NotificationChannel notificationChannel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, NotificationManager.IMPORTANCE_HIGH);
    //setting pattern to disable vibrating
    notificationChannel.enableVibration(false);

    notificationBuilder = new NotificationCompat.Builder(ctx, CHANNEL_ID);
} else {
    notificationBuilder = new NotificationCompat.Builder(ctx);
    notificationBuilder.setVibrate(new long[]{0L});
}

Answer 4

Use NotificationManager.IMPORTANCE_LOW for importance value.

NotificationChannel notificationChannel = new NotificationChannel(
    CHANNEL_ID,
    CHANNEL_NAME,
    NotificationManager.IMPORTANCE_LOW
);

Answer 5

The answer of Ahmadul Hoq which can be found here might be helpful.

Basically you have to enable vibration and set the vibration pattern to 0L. There seems to be a bug on Android Oreo which causes this workaround.

EDIT:

If you are using summary notification this might cause the double vibration. I had the same behaviour until I found out that the summary notification which was grouped together with the incoming notification was causing this issue. You can create an extra notification channel for the summary notification and set the importance for this one to "low". This means the channel for the summary notification will be silent and you should only have sound and vibration coming from the normal incoming notifications.
