將Android設備與C＃Web服務連接時出錯

Question

我正在嘗試將我的android設備與簡單的C＃網絡服務連接，但出現此錯誤

org.xmlpull.v1.XmlpullparserException：預期：START_TAG { http://schemas.xmlsoap.org/soap/envelope/ }信封（java.io.inputStreamReader@1db98270中的位置：START_TAG @ 2：7）

這是我的代碼：

package com.example.khalifa_.webservice;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;

import android.widget.TextView;

public class MainActivity extends Activity
{
    /** Called when the activity is first created. */
    private static final String SOAP_ACTION = "http://tempuri.org/findContact";

    private static final String OPERATION_NAME = "findContact";// your webservice web method name

    private static final String WSDL_TARGET_NAMESPACE = "http://tempuri.org/";

    private static final String SOAP_ADDRESS = "http://192.168.1.3:29824/Service.asmx";
// for the SOAP_ADDRESS, run your web service & see

        StrictMode.setThreadPolicy(policy);
        tvData1 = (TextView)findViewById(R.id.textView1);

        button=(Button)findViewById(R.id.button1);

        button.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,     OPERATION_NAME);
                PropertyInfo propertyInfo = new PropertyInfo();
                propertyInfo.type = PropertyInfo.STRING_CLASS;
                propertyInfo.name = "eid";

                edata =(EditText)findViewById(R.id.editText1);
                studentNo=edata.getText().toString();

                request.addProperty(propertyInfo, studentNo);

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

                envelope.setOutputSoapObject(request);

                HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS);

                try  {
                    httpTransport.call(SOAP_ACTION, envelope);
                    Object response = envelope.getResponse();
                    tvData1.setText(response.toString());
                }  catch (Exception exception)   {
                    tvData1.setText(exception.toString()+"  Or enter number     is not Available!");
                }

                tvData1 = (TextView)findViewById(R.id.textView1);
            }
        });

        //client = new DefaultHttpClient();
        //new Read().execute("text");
    }
}

您必須在后台線程中編寫代碼。 使用asynctask作為后台線程。 有關更多信息， 請參考this 。
