Csharp Xamarin Maui： Worker.DoWork，如何启动一个长时间运行的、事件驱动的任务

在我的.NET Maui Android应用程序中，我试图使用AndroidX.Work.Worker来启动一个长时间运行的进程，该进程侦听来自加速度计的事件.我遇到的问题是，一旦DoWork方法退出，Worker就会终止.因此，我需要通过阻止DoWork退出来保持Worker运行，但我找不到实现这一点的代码.

    public class DropDetectorWorker : AndroidX.Work.Worker
    {
        public override Result DoWork()
        {
            CreateInitialNotificationChannel();
            
            var foregroundInfo = new ForegroundInfo(NotificationId++, BuildInitialNotification());
            SetForegroundAsync(foregroundInfo);
            
            InitialiseDropDetector();
            
            // TODO - prevent DoWork from exiting
            return Result.InvokeSuccess();
        }
        
        private void InitialiseDropDetector()
        {
            _dropDetector.DropDetected += DropDetector_DropDetected;
            _dropDetector.Start();
        }
        
        private void DropDetector_DropDetected(object sender, DropDetectedEventArgs e)
        {
            _lastDropDetected = SystemDate.UtcNow;
            TriggerAutoclaimNotification(e.Magnitude);
        }
        
        private void CreateInitialNotificationChannel()
        {
            NotificationChannel channel = new(INITIAL_NOTIFICATION_CHANNEL_ID, INITIAL_NOTIFICATION_CHANNEL_NAME, NotificationImportance.Default)
            {
                LightColor = Microsoft.Maui.Graphics.Color.FromRgba(0, 0, 255, 0).ToInt(),
                LockscreenVisibility = NotificationVisibility.Public
            };
        
            _notificationManager.CreateNotificationChannel(channel);
        }
        
        private void TriggerAutoclaimNotification(double magnitude)
        {
            var foregroundInfo = new ForegroundInfo(NotificationId, BuildMakeClaimNotification(magnitude));
            SetForegroundAsync(foregroundInfo);
        }
    }
