Android Question StartServiceAt and StopService

[Marcos Alves]

Hello,

I have a doubt. I'm scheduling a service to start every 30 seconds, but I don't need the service running between the intervals... then, I use the code...

Sub Service_Start (StartingIntent As Intent)
      do everything...
     StartServiceAt("",DateTime.Now + 30000,True)
    StopService("")
End Sub

Of course that if I check between the intervals if the service is running (using IsPaused(service)) then I'll have true (for pause). But how can I know if the service is scheduled? And if I start again, even if scheduled, I'll have two scheduled instances or the system will respect the last call and cancel any scheduled time for the service?

Just print a log of the time every time the service stats, what is your target SDK level?

sdk level android-27. Does make difference?

I done a workaround: always before startservice I use CancelScheduledService. Then I know that there is no risk to have two instances running. I think that this approach will always work, doesn't it?

That will work just fine just run it for 30 minutes with logs on every restart so you can see exactly if it's still firing up, but it should be.

ok, thanks @Peter Simpson
