  <pre><code>        Intent actionIntent = new Intent(this, typeof(ConfirmActivity));
          actionIntent.PutExtra("NOTIFY_ID", 1);
          PendingIntent actionPendingIntent = PendingIntent.GetActivity(this, 0, actionIntent, PendingIntentFlags.UpdateCurrent);
          NotificationCompat.Action action = new NotificationCompat.Action.Builder(Resource.Drawable.ic_done_white_64dp_1x,
                      this.Resources.GetString(Resource.String.confirm), actionPendingIntent)
                      .Build();

              .SetSmallIcon(Resource.Drawable.Icon).Extend(new NotificationCompat.WearableExtender().AddAction(action)).Build();
  
          var manager = NotificationManagerCompat.From(this);
          manager.Notify(1, notification);
  
  
          Intent actionIntent2 = new Intent(this, typeof(ConfirmActivity));
          actionIntent2.PutExtra("NOTIFY_ID", 2);
