NavigationManager.StartNavigation return INVALID_PARAMETERS

I’m using HereMaps Sdk for navigation and route calculations. When I try to start a navigation or simulation I get error from INVALID_PARAMETERS…

I can not identify the problem to be able to solve. I already have my routes configured and my map added to the NavigationManager

I am using the example of the own nokia in their github as base. https://github.com/heremaps/here-android-sdk-examples/blob/master/turn-by-turn-navigation/app/src/main/AndroidManifest.xml

//OnEngineInitListener...    
NavigationManager.Instance.SetMap(mapFragment.Map);
NavigationManager.Instance.SetMapUpdateMode(NavigationManager.MapUpdateMode.Position);
var nresult = NavigationManager.Instance.StartTracking();
//nresult return only INVALID_PARAMETERS and navigation dont start

We do not officially support Xamarin. There are the following cases when this error can happen:

1. null passed as route.
2. In case you use RouteOptions.TransportMode.PUBLIC_TRANSPORT
3. route type is UMRoute
4. in other cases - Navigation engine is complex feature (e.g. Map was not init, incorrect voice package and so on).

Sorted out! The device he was using was a Samsung Galaxy S7 with Root and Room customized for android 8.1 After removing the root and returning to the original build the problem has been resolved. I tested it on other devices with android 6,7 and 9. It is also working, as long as root is disabled.
