I have this example (in attached) that schedules a service to show a notification every thurday at 10:30 AM.

In Android 4 it works, but in Android 9 the notification run one time in the first week, but don't show in the next weeks.

I think the Android 9 kills the process.

I checked this post from @Erel Background location tracking, but I don't what is the problem and how to fix it.

Thanks in advance for any help.

Code:
B4X:
Sub Service_Start (StartingIntent As Intent)
    If Starter.running <> True Then
        Dim n As Notification
        n.Initialize2(n.IMPORTANCE_HIGH)
        n.Icon = "icon"
        n.AutoCancel = True
        n.Vibrate = False
        n.Sound = True
        n.SetInfo2("Thursday", "Test of notification...", "odNotifica", Main)
        n.Notify(1)
    End If
    
    Dim t As Long
    t = Functions.SetNextDayAlarm(5, 10, 30)  'thurday
    Log("SetNextAlarmDate> " & DateTime.Date(t) & " " & DateTime.Time(t))
    
    StartServiceAtExact(Me,t,True)

    StopService(Me)

    Service.StopAutomaticForeground
End Sub
B4X:
Sub SetNextDayAlarm(DayOfWeek As Int, Hour As Int, Minute As Int) As Long
    Dim day As Int = DateTime.GetDayOfWeek(DateTime.Now)
    If day >= DayOfWeek Then DayOfWeek = DayOfWeek + 7
    Dim d As Long = DateTime.Add(DateTime.Now, 0, 0, DayOfWeek - day)
    Return DateUtils.SetDateAndTime(DateTime.GetYear(d), DateTime.GetMonth(d), DateTime.GetDayOfMonth(d), Hour, Minute, 0)
End Sub

B4X:
Sub StartNotification
    Dim t As Long
    t = Functions.SetNextDayAlarm(5, 10, 30)  'thurday
    Log(t)
    Log("SetNextAlarmDate> " & DateTime.Date(t) & " " & DateTime.Time(t))

    CancelScheduledService(Alarme)
    
    StartServiceAtExact(Alarme,t,True)
End Sub

It will probably be easier to implement with push notifications.
The notification is to remember the user to open the app and I want that notification works even the device is not connect to the internet.

Maybe the device was restarted during the week?
I don't check it. If yes, what I need to do to notification restart in the right day?
