Android Studio, ksoap2 http request failed, 404

Question

I am trying to call webservice created by Swagger UI (WADL), I use the same way that I use for calling webservice WSDL but it does not work and I got error HTTP request failed, HTTP status: 404

 

org.ksoap2.transport.HttpResponseException: HTTP request failed, HTTP status: 404 

 

And I use this ksoap

ksoap2-android-assembly-3.4.0-jar-with-dependencies 

 

So how can I solve this problem?
