Description Emmanuel.Guenther 2017-11-30 15:53:58 UTC
As soon as the IApp.Invoke method is called with a parameter, the following exception is thrown:

System.Exception : Error while performing Invoke("SetMainPage", "LoginView")   ----> System.Net.Http.HttpRequestException : Fehler beim Senden der Anforderung.   ----> System.Net.WebException : Die zugrunde liegende Verbindung wurde geschlossen: Die Verbindung wurde unerwartet getrennt..    bei Xamarin.UITest.Utils.ErrorReporting.With[T](Func`1 func, Object[] args, String memberName)    bei Xamarin.UITest.Android.AndroidApp.Invoke(String methodName, Object argument)    bei UITest.OnboardingTest.WelcomeScreenShowsUp() in D:\Projekte\Sonstige\UEBE\UEBE_CycloTestApp\code\V2\UITest\OnboardingTest.cs:Zeile 79. --HttpRequestException    bei Xamarin.UITest.Shared.Http.HttpClient.SendData(String endpoint, String method, HttpContent content, ExceptionPolicy exceptionPolicy, Nullable`1 timeOut)    bei Xamarin.UITest.Shared.Http.HttpClient.Post(String endpoint, String arguments, ExceptionPolicy exceptionPolicy, Nullable`1 timeOut)    bei Xamarin.UITest.Android.AndroidGestures.Invoke(String methodName, Object[] arguments)    bei Xamarin.UITest.Utils.ErrorReporting.With[T](Func`1 func, Object[] args, String memberName) --WebException    bei System.Net.HttpWebRequest.EndGetResponse(IAsyncResult asyncResult)    bei System.Net.Http.HttpClientHandler.GetResponseCallback(IAsyncResult ar)

UITest code to invoke backdoor:
this.app.Invoke("SetMainPage", "LoginView");

Corresponding method in my Android MainActivity:
public void SetMainPage(string arg){..}

Without parameter, everything is working fine.

I'm using the latest version of Xamarin.UITest and the Internet permission is set for the Android project.
