How can I get Notification Heads-Up working with SetPriority?

I've got a notification in my Android app (this app is part of XamForms).
I can get notifications working, however, I cannot get the notification to show up as a Heads-Up notification.

The two issues I'm having are as follows.

  1. The SetPriority() method in the Navigation.Builder takes an int instead of NotificationPriority.High enum
  2. Even setting the int to 2 which is MAX as per the documentation, the notification shows up in the shade, but does not display a HUD.

    using Android.App;
    using Android.Content;
    using Android.Content.Res;
    using Android.Graphics;
    using Android.Support.V4.App;
    using Java.Lang;
    using Notification = TimeTracker.Notifications.Notification;

    namespace TimeTracker.Droid.Notifications
    public class LocalNotificationReceiver : BroadcastReceiver
    private static readonly Resources Resources = Application.Context.Resources;

        public override void OnReceive(Context context, Intent intent)
            var notificationId = intent.GetIntExtra("id",-1); // default value is -1 because it should never associate with an enum.
            var notification = new Notification
                NotificationId = notificationId
            if (notification.ShouldNotify())
                var iconColor = Resources.GetColor(Resource.Color.notification_icon_color);
                var notIntent = new Intent(context, typeof(MainActivity));
                var contentIntent = PendingIntent.GetActivity(context, notificationId, notIntent, PendingIntentFlags.CancelCurrent);
                var manager = NotificationManager.FromContext(context);
                var style = new Android.App.Notification.BigTextStyle();
                const int resourceId = Resource.Drawable.ic_launcher;
                var wearableExtender = new Android.App.Notification.WearableExtender()
                    .SetBackground(BitmapFactory.DecodeResource(Resources, resourceId));
                //Generate a notification
                var nativeNotificationBuilder = new Android.App.Notification.Builder(context)
                manager.Notify(notificationId, nativeNotificationBuilder.Build());
