Android Question StartServiceAt with Intent

[Graeme Tacon]

I picked up this code a while ago and now need to do something similar, i.e. sending an action to my service, but it doesn't work.

Sub schedule_service(secs As Int)
    Dim i As Intent, x As Long
    x = DateTime.Now + (secs * DateTime.TicksPerSecond)
    Log("Scheduling at " & x)
    i.Initialize("", "")
    i.SetComponent(Application.PackageName & "/.testservice")
    i.Action = "x" & secs
      StartServiceAt(i,x,True)
End Sub

I'm getting the following error:

[DEBUG]
--------- beginning of main

line 62 is the startserviceat line.

What is wrong please ?

It will not work. StartServiceAt expects a service. It actually starts the service by first starting the internal broadcast receiver.

As there is only one active scheduled task you can save the action in a file and read it in Service_Start.
