LocalNotification is not removing when application completely close.

[bangaras]

Hello, I am new to .NET MAUI Blazor,
I have tried this all method still my notification shows when app completely close/destroy. Also not getting that when my app completely closes then it executing OnDisappearing and OnDestroy from MainActivity or not. Please check

LocalNotificationCenter.Current.Cancel();
LocalNotificationCenter.Current.CancelAll();
LocalNotificationCenter.Current.Clear();
LocalNotificationCenter.Current.ClearAll();

//MainPage.xaml.cs

protected override void OnDisappearing()
    {
        LocalNotificationCenter.Current.CancelAll();

        base.OnDisappearing();
    }

//MainActivity.cs

    protected override void OnDestroy()
    {
        LocalNotificationCenter.Current.CancelAll();

        base.OnDestroy();
    }

Hi @bangaras I will check. But I assume in android you cannot clean already fired notifications.

Can you clear an already fired notification using cancel , if the app was running in the foreground?

[bangaras]

Hello @thudugala, I can clear fired notification when app is running with
LocalNotificationCenter.Current.CancelAll(); LocalNotificationCenter.Current.ClearAll();

But when I close the app completely that time I am not able to execute this CancelAll or ClearAll methods. I set these methods on 'OnDestory', 'OnDisappearing' events but its not executing when app closes completely.

Can you suggest me any different way or any solution for clearing notification when app closes completely.
