Android Question How to create timer-like service?

[Mostez]

Is there a simple code example for how to create timer-like service? I tried to use a timer to send SMSs at some interval but failed to keep it alive! here is what I did, I use android 6 phone and may upgrade to android 10.

Sub SMSQueueTimer_Tick()
Sleep(0)
Dim SMS As clsSMS
SMS.Initialize
SMSQueueTimer.Enabled = False
lblLastSMSStatus.Text = "Listening..."
progsSMScontrolPanel.Visible = True
Wait For (CallSub3(SMS, "GetInfo","",True)) Complete (Isget As Boolean)
progsSMScontrolPanel.Visible = False

If Isget Then
    Sleep(0)
    
    lblsmsID.Text = ""
    lblsmsFrom.Text = ""
    lblsmsTo.Text = ""
    lblCreatedDateTime.Text = ""
    
    lblLastSMSStatus.Text = "Sending..."
    'dont change method below
    Dim smsTo As String = SMS.Info.smsTo
    Dim smsBody As String = SMS.Info.Body
    Dim smsID As String = SMS.Info.smsID
    
    lblsmsID.Text = smsID
    lblsmsFrom.Text = SMS.Info.SenderID
    lblsmsTo.Text = smsTo
    lblCreatedDateTime.Text = SMS.Info.CreatedDateTime
    
    SendLargeSms(smsTo,smsBody,smsID)
    '---------------------------------------
    
Else
    ErrorsCounter = ErrorsCounter + 1
    lblsmsErrors.Text = ErrorsCounter
    lblLastSMSStatus.Text = "Server\Data Error"
End If

    SMSQueueTimer.Enabled = True
End Sub
