VibrationPattern not working as expected

I am having trouble getting VibrationPattern to work. I tried using a pattern where the phone waits for a second and then vibrates for a second and have that done 3 times in a row. However, the actual vibration pattern is the default one for the phone I am testing with (Android 12), more precisely just two bursts of vibration with very little pause in between.

Here is my code:

LocalNotificationCenter.Current.Clear(_notificationId);
var notification = new NotificationRequest
{
    NotificationId = _notificationId,
    Title = $"{period.Name} started!",
    Subtitle = scheduleName,
    Description = $"Period {period.Name} just started!",
    CategoryType = NotificationCategoryType.Alarm,
    Android = new AndroidOptions
    {
        Color = new AndroidColor(period.Color.ToInt()),
        VibrationPattern = new long[] { 1000, 1000, 1000, 1000, 1000, 1000 }
    }
};

await LocalNotificationCenter.Current.Show(notification);

Am I doing something wrong?

@thudugala

thanks for your response.

It’s finally working now. I had to do two things:

1. move the creation of the channel to mauiprogram.cs: .UseLocalNotification(config => { config.AddAndroid(android => … ETC…

2. I had to set Silent property (of the NotificationRequest) to false. Apparently this was set to true.

After these changes the virbration works as expected! Thanks again!

You can only set the vibration pattern before the channel created.

Have try uninstalling and installing the app again?
