重启设备时，我的服务不会自动启动

Question

我想在设备重启时自动启动服务。之后，我希望执行服务中的操作。我写了一个代码，但在重启设备时它失败了。我有2节课。这些是＆＃39; AdroidService＆＃39;和＆＃39; DetectBootUp＆＃39;。我认为＆＃39; AndroidManifest.xml＆＃39;。

中存在错误

DetectBootUp.cs

namespace NotifyExp2.Droid.ReminderService
{
    [BroadcastReceiver]
    [IntentFilter(new[] { Intent.ActionBootCompleted })]
    class DetectBootUp : BroadcastReceiver
    {
        public override void OnReceive(Context context, Intent intent)
        {
            Intent bootUp = new Intent(context.ApplicationContext, typeof(AndroidService));
            bootUp.AddFlags(ActivityFlags.ExcludeStoppedPackages);
            bootUp.AddFlags(ActivityFlags.IncludeStoppedPackages);
            context.StartService(bootUp);
        }
    }
}

AndroidService.cs

namespace NotifyExp2.Droid.ReminderService
{
    [Service]
    public class AndroidService : Service
    {
        public override void OnCreate()
        {
            Toast.MakeText(this, "Service Created", ToastLength.Long).Show();
            Log.Debug("BroadCastReceiverBoot", "OnCreate");
        }
        public override IBinder OnBind(Intent intent)
        {
            return null;
        }
        public override void OnDestroy()
        {
            Toast.MakeText(this, "Service Destroyed", ToastLength.Long).Show();
            Log.Debug("BroadCastReceiverBoot", "onDestroy");
            ApplicationContext.StartService(new Intent(ApplicationContext, typeof(AndroidService)));
        }
        [return: GeneratedEnum]
        public override StartCommandResult OnStartCommand(Intent intent, [GeneratedEnum] StartCommandFlags flags, int startId)
        {
            Toast.MakeText(this, "Service Started - " + DateTime.Now.Hour + ":" + DateTime.Now.Minute.ToString() + ":" + DateTime.Now.Second.ToString(), ToastLength.Long).Show();
            Log.Debug("BroadCastReceiverBoot", "OnStart");
            return StartCommandResult.Sticky;
        }
    }
}

的AndroidManifest.xml
