用于android的Java Web服务和ksoap2

但我们总是会得到一个版本，下面也会提到

I am implenting java web services for android project and calling with KSOAP2.
My Code is mention below..

package com.android.service;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class MyAndroidService extends Activity {
    private static final String NAMESPACE = "http://project.com/";
    private static final String METHOD_NAME = "sayHello";
    String SOAP_ACTION = "http://project.com/sayHello";
    private static final String URL = 
            "http://localhost:8080/MyProject/wsdl/Hello.wsdl";  
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        TextView tv=(TextView)findViewById(R.id.text);

        try{
            SoapObject object=new SoapObject(NAMESPACE, METHOD_NAME);
            object.addProperty("name", "dev");
            SoapSerializationEnvelope envelope=new SoapSerializationEnvelope(SoapEnvelope.VER11);
            envelope.setOutputSoapObject(object);
            HttpTransportSE httpTransportSE=new HttpTransportSE(URL);
            httpTransportSE.call(SOAP_ACTION, envelope);
            Object result=envelope.getResponse();
            System.out.println("result :"+result.toString());
        }catch (Exception e) {
            System.out.println(e);
        }
    }
}

它显然无法在运行时找到ksoap2 jar

您可以在构建apk时检查您的jar是否已导出：在project Properties>Java构建路径中，转到“Order and Export”文件夹并填写与您的jar对应的复选框。和重建。

我已经做了，但之后它也给出了相同的异常08-28 18:26:06.605:i/System.out（7310）：异常：org.xmlpull.v1.XmlPullParserException:预期：START_TAG{}信封（Stase:StistyTAG，这样您就不会再有以前的NoCuffDeFror错误了吗？谢谢先生，但是在那之后，我们就像上面一样发生了异常，您能帮助我解决它吗？这看起来是一个完全不同的问题（显然是一个响应解析的错误）。您应该考虑为此创建一个新的问题。
