Java android中的Webservice对象响应

我正在尝试使用我在c#中创建的这个Web服务：

它获取id并返回具有值的对象

我试着在android应用程序中调用它，如下所示：

mainactivty.java：

 public class MainActivity extends Activity {

boolean timeoutexcep=false,httpexcep=false,generalexcep=false;
    String nam="lama";


String Id,name,grade;

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

    new Persondetails().execute();
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

class Persondetails extends AsyncTask<Void, Void, Void> {
    private final ProgressDialog dialog = new ProgressDialog(MainActivity.this);

    @Override
    protected void onPreExecute() {
        this.dialog.setMessage("Loading data");
        this.dialog.show();
    }


    @Override
    protected Void doInBackground(Void... unused) {

        final String NAMESPACE = "http://tempuri.org/";
        final String URL = "http://192.168.1.5:90/myWebService.asmx";
        final String SOAP_ACTION = "http://tempuri.org/StudentDetails";
        final String METHOD_NAME = "StudentDetails";

        SoapObject request2 = new SoapObject(NAMESPACE, METHOD_NAME);
        request2.addProperty("sName", nam);


        Bean C = new Bean();
        PropertyInfo pi = new PropertyInfo();
        pi.setName("Bean");
        pi.setValue(C);
        pi.setType(C.getClass());
        request2.addProperty(pi);
        SoapSerializationEnvelope envelope2 = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope2.dotNet = true;
        envelope2.setOutputSoapObject(request2);
        envelope2.addMapping(NAMESPACE, "Bean", new Bean().getClass());
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        androidHttpTransport.debug = true;

        try {
            androidHttpTransport.call(SOAP_ACTION, envelope2);
            SoapObject response2 = (SoapObject) envelope2.getResponse();


            System.out.println("check Request" + request2);
            System.out.println("check response" + response2);

            envelope2.addMapping(NAMESPACE, "Panchayat",new Bean().getClass());
            androidHttpTransport.call(SOAP_ACTION, envelope2);
            Bean[] personobj = new Bean[response2.getPropertyCount()];
            Bean beanobj = new Bean();

            for (int j = 0; j < personobj.length; j++) {
                SoapObject pii = (SoapObject) response2.getProperty(j);
                beanobj.Id = Integer.parseInt(pii.getProperty(1).toString());
                beanobj.name = pii.getProperty(2).toString();
                beanobj.grade = pii.getProperty(3).toString();

                personobj[j] = beanobj;
            }

            name=beanobj.name;
            Id=String.valueOf(beanobj.Id);
            grade=beanobj.grade;

        }
        catch(SocketTimeoutException e){
            timeoutexcep=true;
            e.printStackTrace();
        }
        catch(ConnectException e){
            httpexcep=true;
            e.printStackTrace();
        }
        catch (Exception e) {
            generalexcep=true;
            e.printStackTrace();
        }
        return null;

    }
    @Override
    protected void onPostExecute(Void result) {
        if (this.dialog.isShowing()) {
            this.dialog.dismiss();
        }

        if(timeoutexcep){
            Toast.makeText(MainActivity.this, "Unable to connect to server, Please try again later",Toast.LENGTH_LONG).show();
        }
        else if(httpexcep){
            Toast.makeText(MainActivity.this, "Please check your Internet connection",Toast.LENGTH_LONG).show();
        }
        else if(generalexcep){
            Toast.makeText(MainActivity.this, "Please try later",Toast.LENGTH_LONG).show();
        }

        else {
            display();
        }
        timeoutexcep=false;httpexcep=false;generalexcep=false;
    }

    private void display() {

        TextView t1=(TextView)findViewById(R.id.name);
        t1.setText(name);
        TextView t2=(TextView)findViewById(R.id.palce);
        t2.setText(grade);
        TextView t3=(TextView)findViewById(R.id.age);
        t3.setText(Id);
        TextView t4=(TextView)findViewById(R.id.phone);
        t4.setText("COOOL!");
    }
}
 }

但这总是会在稍后用try干杯，我不知道我的代码出了什么问题？有人能帮忙吗？

请稍等片刻，看看您遇到了什么错误。张贴堆栈trace@NitinMesta如果这样做，我会出现多个错误。。
