I've built a network dataset with street feature class and GTFS data.
To publish the network dataset as Network Analysis service, I followed the instructions of the guide and in particular the "Using your network dataset with ArcGIS Server".
When I published, a warning message with code 24066 "The network dataset uses a custom evaluator" is displayed.
Finally I published the Network Analysis service on ArcGIS Server.
The service works very well and when I load it on ArcMap the Find Route tool works perfectly.
But when I use the service from my Xamarin Android application and try to create a RouteTask, I catch this error:
Error: Esri.ArcGISRuntime.ArcGISRuntimeException: Internal error: Data type Unknown
I think that Transit Evaluator type is not recognised at run time.
This is my work environment:
Windows 10 Pro (v. 1809)
Visual Studio 2017 Community with Xamarin
ArcGIS Runtime SDK for .Net (v. 100.5.0)
Xamarin.Android... library packages (v. 184.108.40.206)
ArcGIS Server 10.5
Can anyone help me?
