XmlPullParserException:意外类型（位置：END_文档null@1：1在java.io.InputStreamReader中），在Android应用程序中使用KSOAP2库

这是我在这里的第一个问题，我一直在寻找解决方案，但我所发现的只是类似的情况或没有答案的问题。因此，我对android进行了一个简单的测试，它使用一个本地Web服务，提供以下主体：

我遵循了

httpTransport.call

，注意到当它到达方法

时，这个.parseResponse（信封，（InputStream）是）

在

HttpTransportSE

类中，它抛出异常

org.xmlpull.v1.XmlPullParserException:意外类型（位置：END_文档null@1：1在java.io中。InputStreamReader@286e958)

有人能帮我吗？

大家好，谢谢你们的提醒，但我解决了这个问题，结果我犯了一个错误，url不正确，应该在哪里。现在正在运行。

同样的错误和其他一些问题。解决方案似乎是使用ksoap库的更新版本。（我想是吧）。你能试着确认一下这是否有用吗？你展示的XML格式不好，任何东西都无法解析它。

String url = "http://XX.X.X.X:8080/livro_android_xfire/services/Calculadora?wsdl"

SoapObject soap = new SoapObject("urn:Calculadora", "soma");

// Adiciona os parâmetros para a soma
soap.addProperty("n1", n1);
soap.addProperty("n2", n2);

// Cria o envelope com o objeto SOAP
SoapSerializationEnvelope envelope = new   SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(soap);

Log.i(TAG, "Calling WebService: " + url);

// Cria o HttpTransport para enviar os dados (SOAP)
HttpTransportSE httpTransport = new LivroHttpTransport(url);
httpTransport.debug = true;

// Faz a requisição
httpTransport.call("", envelope);
