android to consume a .net web service

I am using a few links to create a web service in my android....they make it sound like copy and paste code..but when I did that..I am getting all these errors...like:

1)Soap object cannot be resolved
2)envelope.setOutputSoapObject(request); >>>>UNDEFINED
3)  Object result = (Object)envelope.getResponse(); >>>>GETRESPONSE IS UNDEFINED
4)    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); >>>>CANNOT BE RESOLVED TO A VARAIBLE....

also how can I consume this into a dataset?
