Android Question Service is killed in 3-7 minutes, what is wrong?

Good day dear programmers. (I use Google as a translator, so do not swear strongly) Briefly, there is an oreo and you need a service that will check a certain URL every 20 seconds and cause a certain action. But the current code does not work much time, oreo kills it. What not so please tell me. Thank.

#Region  Service Attributes
    #StartAtBoot: True
#End Region

Sub Process_Globals
    Dim pw As PhoneWakeState
    Dim n As Notification
End Sub

Sub Service_Create
    Service.AutomaticForegroundMode=Service.AUTOMATIC_FOREGROUND_ALWAYS
End Sub

Sub Service_Start (StartingIntent As Intent)
    pw.PartialLock
    Service.StopAutomaticForeground
    n.Initialize
    n.SetInfo("Check data", "Run",Main)
    Service.StartForeground(1,n)
   
    Log("run")
    Wait For (check)  Complete (Result As Int)
    StartServiceAt("",DateTime.Now+20*DateTime.TicksPerSecond,True)
    Service.StopAutomaticForeground
   
End Sub

Sub Service_Destroy

End Sub

Private Sub check() As ResumableSub
    Dim j As HttpJob
    j.Initialize("",Me)
    j.Download("http://www.site.com/data.txt")
    Wait For (j) JobDone(j As HttpJob)
    If j.Success Then
        Log("ok")
        Dim str As String=j.GetString
    End If
    j.Release
    Return 1
End Sub

You can't start service in 20 sec interval, better start service as foreground (as you already do) and use timer inside service, without stopping service.

if I knew how to do this (can you set an example?

The user can swipe the program window, but the process still works in the background (3-7 minutes - always in different ways)

I have already tried many options (all drive to one

1. Don't use StartServiceAt. Use a timer instead.

2. Don't stop foreground mode.

Erel, thanks for the advice (you are always on top), and if you do not mind, you can show an example?

Start with:

Sub Service_Create
    Service.AutomaticForegroundMode=Service.AUTOMATIC_FOREGROUND_ALWAYS
pw.PartialLock
End Sub

Sub Service_Start (StartingIntent As Intent)
    
    Do While True
    Log("run")
    Wait For (check)  Complete (Result As Int)
    Sleep(20000)
    Loop   
End Sub
