After several months offline I decided to implement the needed changes in order to make it work again with my current ISP. If this is the first time you see this, I have implemented an online version of this project.
Just check the link on the top of this website ( http://www.davidgouveia.net/android-ksoap2-stub-generator/ ). All you need to do is input the url of the wsdl that you want to generate the stub.
Have fun 🙂
