I developed an Android app in kotlin which should launch a Maplestory game server service on foreground when clicking Start button and stop the service when clicking Stop button.
Application will throw “Service not registered” error after step 3:

1. Click the start button to launch the service.
2. Minimize the app and back to desktop.
3. Re-enter the app and click the stop button.

So I’m confused what’s the right approach to launch and terminate the service ?

Method when clicking buttons:

Service definition:

fun doBindService(
    context: Context,
    connection: ServiceConnection,
    serviceIntent: Intent
) {
    context.bindService(serviceIntent, connection, Context.BIND_AUTO_CREATE)
}

fun startMapleServer(context: Context, serviceIntent : Intent) {
    startForegroundService(context, serviceIntent)
}


fun stopMapleServer(context: Context, serviceIntent : Intent, connection : ServiceConnection) {
    context.unbindService(connection)
    context.stopService(serviceIntent)
}
