public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity

{
.....
NotificationCenter.NotifyNotificationTapped(Intent);
}
protected override void OnNewIntent(Intent intent)
{
NotificationCenter.NotifyNotificationTapped(intent);
base.OnNewIntent(intent);
}
}
You must get permission from the user to allow the app to show local notifications. Also, To receive Local Notification tap event. Include the following code in the FinishedLaunching() method of AppDelegate:
