Android Question App starting from service

[Scantech]

One of customers complaining app starting up every 30 minutes. I have not able to duplicate it. Is there any flaws in the code below which can startup the Main?

Sub Service_Create

    Service.AutomaticForegroundMode = Service.AUTOMATIC_FOREGROUND_NEVER 'we are handling it ourselves

    tmrTrip.Initialize("tmrTrip", 500)                         'every 500 milliseconds   
    tmrTripSaveData.Initialize("tmrTripSaveData", 60000)     '1 minutes
    GPS1.Initialize("GPS")   
    PhoneEvent.Initialize("PhoneEvents")
    
    StateManager.LoadStateTrip                'load these
    StateManager.LoadStateMaintenance        'load these at first startup
    StateManager.LoadStateSpeedLimiter        'load speed limiter value
        
    CheckPreferenceState
    
    Starter.pws.PartialLock                    'Important so it will not CPU Sleep

    TripIcon1 = LoadBitmapResize(File.DirAssets, "tripicon.png", 24dip, 24dip, True)
    TripIcon2 = LoadBitmapResize(File.DirAssets, "mainicon.png", 24dip, 24dip, True)

End Sub
Sub Service_Start (StartingIntent As Intent)
    StartServiceAt(Me, DateTime.Now + 30 * DateTime.TicksPerMinute, True) '30 minutes

    If StateManager.blnUseGPS = True Then
        Log("Timer and Notification turned on in START..")
        Service.StartForeground(1, CreateNotification("..."))
        
        CallCreateNotification("...", "")
        
        TurnOnTmrTrip
    End If
    
    'not used.  used for tracking buttons in notification
'    If StartingIntent.IsInitialized Then
'        Log(StartingIntent.Action)
'    End If
    
End Sub

StartServiceAt(Me, DateTime.Now + 30 * DateTime.TicksPerMinute, True) '30 minutes

this causes your service to start every 30 minutes

TurnOnTmrTrip

what does this method do?

 

[Scantech]

Sub TurnOnTmrTrip
    If tmrTrip.Enabled = False Then
        startTime = DateTime.Now ' do not use firstReset boolean
        Log("Turn Timer ON")
        tmrTrip.Enabled = True
    End If
End Sub

The customer may be clicking on the notification which causes the app to start. His first email "but every half hour or so, it starts up automatically, and puts a persistent notification in my status" and His last reply "My objection is having to dismiss a notification ever half hour". I just emailed him for clarification with the app starting.

Thanks
