            ToolbarResource = Resource.Layout.Toolbar;
            base.OnCreate(bundle);
            global::Xamarin.Forms.Forms.Init(this, bundle);
            LoadApplication(new App());
            // Add the line above

        {
            base.OnNewIntent(intent);
            if (intent.HasExtra(LocalNotificationsImplementation.LocalNotificationIntentKey))
            {
                // Do something with the notification Id...
            }
        }
}

Hi @rdrscan I got this code working thanks to you, but I don't know why when I have more than one notification on the OnNewIntent always get me the last notification Id and not the one I am click in it.

Solved just update public void Show(string title, string body, int id, DateTime notifyTime) this line var pendingIntent = PendingIntent.GetBroadcast(Application.Context, 0, intent, PendingIntentFlags.CancelCurrent);

to this var pendingIntent = PendingIntent.GetBroadcast(Application.Context, id, intent, PendingIntentFlags.CancelCurrent);
