Android Question App Not Exiting From Button - Can't Work Out Why

[woodpecker]

My app uses one activity (Main), Starter service and a service called scan. I am trying to shut down the whole app by clicking an Exit button in the menu but its not working and I can't see why.

I have a boolean called killapp.

The button calls this sub:-

Sub mnuExit_Click
    killapp = True
    StopService(scan)
    StopService(Starter)
    Activity.Finish
End Sub

In Activity_Pause and Activity_Resume I have this:-

If killapp = True Then
        admin.Disable
        pw.ReleaseKeepAlive
        Log("Kill App is " & killapp)
        StopService(scan)
        StopService(Starter)
        Activity.Finish
    End If

The app appears to close but is still open (or at least partially open), in the log I see as below, how can I debug what is not closing properly?

Try ExitApplication after activity.finish

Try ExitApplication after activity.finish

Its actually worse with that, the app completely restarts.

Any ideas?

It's impossible to say something without a code.
For example, I see StopService (Starter). In B4A 8.3 Destroy event happens, but service continue to work. Probably, you app doesn't expect this.

Or ExitApplication. It not always kills the application. B4A uses System.exit (0), which restarts the app with one fewer activity on the stack.
So, if you called activity Two from activity Main, and System.exit (0) is called in activity Two, then the application will be killed and started immediately with only one activity (Main). See attached sample

It is a mistake to call ExitApplication and it is also a mistake to stop the starter service.

You should close the activity and let the OS handle the app life cycle like it does with all apps.
