How to change/remove notification icon?

[pavelustenko]

When I set notificationIconSmall, the service work as expected, but the notification turns into "Application is running" notification. My Config is:
BackgroundGeolocation.configure({
desiredAccuracy: BackgroundGeolocation.MEDIUM_ACCURACY,
stationaryRadius: 50,
distanceFilter: 50,
notificationTitle: 'Служба местоположения',
notificationText: 'запущена',
debug: false,
startOnBoot: false,
stopOnTerminate: true,
locationProvider: BackgroundGeolocation.ACTIVITY_PROVIDER,
interval: 10000,
notificationIconSmall: 'ic_notification',
fastestInterval: 10000,
activitiesInterval: 10000,
stopOnStillActivity: false,
});
It seems to be a documentation lack on this case.
