Question

我只是尝试使用我创建的Web服务执行简单的Web服务数据提取。当我去运行该程序时，它崩溃了我。我已经搜索过这个问题并没有运气，有人可以帮帮我吗？

public void getMessage() {
    private final String NAMESPACE = "http://tempuri.org/";
    private final String URL = "http://10.19.9.148/RFID/Service1.asmx";
    private final String SOAP_ACTION = "http://tempuri.org/HelloWorld";
    private final String METHOD_NAME = "HelloWorld";
    private String TAG = "SOAP";

    private static String message;


    //Create request
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
    //Property which holds input parameters
    PropertyInfo messagePI = new PropertyInfo();
    //Set Name
    messagePI.setName("Practice");
    //Set Value
    messagePI.setValue(messagePI);
    //Set dataType
    messagePI.setType(String.class);
    //Add the property to request object
    request.addProperty(messagePI);
    //Create envelope
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
            SoapEnvelope.VER11);
    envelope.dotNet = true;
    //Set output SOAP object
    envelope.setOutputSoapObject(request);
    //Create HTTP call object
    HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

    try {
        //Invoke web service
        androidHttpTransport.call(SOAP_ACTION, envelope);
        //Get the response
        SoapObject result = (SoapObject) envelope.bodyIn;
        //Assign it to fahren static variable
       // message = response.toString();

        if(result !=null){
            tv.setText(result.getProperty(0).toString());
        }


        //tv.setText("" + results);

    } catch (Exception e) {
        tv.setText(e.getMessage());
        //e.printStackTrace();
    }
}

当我在调试模式中单步执行时，它会在行androidHttpTransport.call(SOAP_ACTION, envelope);处出错，然后在我的日志中显示
