在调用Ksoap2时在android中调试时遇到BaseClassLoader.Class未找到运行时错误

我正在使用EclipseHelios开发android应用程序。 我制作了一个.NETWeb服务，然后制作了一个android应用程序，在其中我使用Ksoap2 jar文件调用web服务。 我查看此链接以获取帮助 我下载了带有依赖项的android ksoap2.jar文件 然后使用构建路径添加jar文件 一切进展顺利，但每当我运行或调试应用程序时，它都会给我一个错误 随叫随到的soap方法 BaseClassLoader.Class Not found错误请附加源 在日志cat中，无法找到类org.ksoap2.serialization。Soap对象，即使该类存在于库中

This is my soap class

package com.nrf;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;


public class CallSoap 
{
    public String SOAP_ACTION;

    public String OPERATION_NAME; 

    public  final String WSDL_TARGET_NAMESPACE = "NRF_Cargo_App";

    public  final String SOAP_ADDRESS = "http://localhost:5265/NRF_Cargo_Service.asmx";

    public CallSoap() 
    { 
    }

    public String Call(String a,String b)
    {
            SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,OPERATION_NAME);
            PropertyInfo pi = new PropertyInfo();

            pi.setName("userName");
            pi.setValue(a);
            pi.setType(String.class);
            request.addProperty(pi);

            pi=new PropertyInfo();
            pi.setName("Password");
            pi.setValue(b);
            pi.setType(String.class);
            request.addProperty(pi);  

            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
            envelope.dotNet = true;

            envelope.setOutputSoapObject(request);

            HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS);
            Object response=null;

    try
    {
            httpTransport.call(SOAP_ACTION, envelope);
            response = envelope.getResponse();

    }
    catch (Exception exception)
    {
            response=exception.toString();
    }
            return response.toString();
    }
}

This is my MainActivityclass

package com.nrf;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

public class MainActivity extends Activity 
{

Button btnlogin;

@Override
protected void onCreate(Bundle savedInstanceState) 
{
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btnlogin = (Button) findViewById(R.id.btnsign);        

        btnlogin.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub

                CallSoap cs = new CallSoap();
                cs.OPERATION_NAME = "UserLogin";
                cs.SOAP_ACTION ="NRF_Cargo_App/UserLogin";
                String resp=cs.Call("Numair", "1234");

            }
        });
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

Please help me for making this app run
or suggest me another easy way of calling .net web-service in android.Thanks

对于错误日志Cat

试试这个：

右键单击已导入-->确定的项目-->转到构建路径-->配置构建路径-->内部订单和导出标记检查库

---

然后清理您的项目。

我尝试过多次这种方法。没有成功。我可以给您我的项目样本，您可以自己尝试。
