Android Question Error message from Starter service

[Amalgamated Sugar]

Hello all!

I've been a member for a little over a year, so I've mainly been reading posts and tutorials. I've recently tried creating a service that would make a toast message appear every 30 seconds, as a test in concept.

When I run 'StartServiceAt' from within the Starter service, I get the following error message in the logs:

The Starter service should never be started from a receiver.

The toast message stills runs, but the log message is in red, which implies something important. I'm still new at coding, so it's entirely possible that I don't understand Starter service/Services in General completely.

Here is my code:

Sub Process_Globals
 LogColor("Process_Globals being created from Starter service.", Colors.Magenta)
 Dim testString As String

End Sub

Sub Service_Create
 testString = "This is a test from the Starter service"

End Sub

Sub Service_Start (StartingIntent As Intent)
 ToastMessageShow(testString, False)
 StartServiceAt(Me, DateTime.Now + 30000, True)
 
End Sub

You should never try to start the starter service, it starts itself.
Create a new service module and put your code in there, now start your new service module using StartService(...) from the original starter module.

I've recently tried creating a service that would make a toast message appear every 30 seconds, as a test in concept.

Note that it is not possible to use StartServiceAt to start the service every 30 seconds. The OS will ignore it at some point. The minimum interval is 10 minutes or more.

If you really want to do something every 30 seconds then you should use a foreground service that is kept running.

Awesome! Thank you both! This was the direction I need to be pointed down!

Would it make more sense to use a timer to do something every 30 seconds?

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.
    Dim Timer2 As Timer
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    Activity.LoadLayout("youActivityName")
      
    Timer2.Initialize ("Timer2",30000)
    Timer2.Enabled = True
  
End Sub

to do something every 30 seconds

Setup the timer with 30000 instead of 500.

You are correct, I made a math error because the number is in milliseconds. For 30 seconds it should be 30,000.
