    this.progressDialog = progressDialog;
    this.mActivity = activity;
    this.context = context;
}

This happened to me once, i changed from SoapPrimitive to Object, then cast it, and it worked. So give it a try. This is may not be relevant but if you are writing your web service in dotnet, make sure you specify that in your envelop by using envelop.dotnet = true;
