Webservices on android

Hello everyone,

I'm currently trying to use a webservice in my project, and it does work in the editor.

However, after building the apk and installing it on my device (Moto G4, Nougat). I get t$$anonymous$$s exception:

ArgumentException: Item has already been added. Key in dictionary: ':System.Object[]:::' Key being added: ':System.Object[]:::'

The Exception occurs, when I try to construct the object (MyWebservice service = new MyWebservice()).

Wit$$anonymous$$n the constructed webservice-file (webservice.cs) I can't find any dictionaries. How do I get access to the dictionary or how do I change the key, w$$anonymous$$ch is used for the new object.

With greetings from Germany
