Question

我想在android studio中使用ksoap lib。但我还没有得到足够的承认。（我总是使用Volley lib从php api发送/接收，它工作正常。）

网址： http://sms141.ir/sms141_webservice.asmx

我的职能：

public object[] CheckUsers(string number , string user  , string pass)

SOAP_ACTION和NAMESPACE变量是否正确？

private static final String SOAP_ACTION = "http://sms141.ir/CheckUsers";
private static final String METHOD_NAME = "CheckUsers";
private static final String NAMESPACE = "http://sms141.ir";
private static final String URL = "http://sms141.ir/sms141_webservice.asmx";


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

    myAsyncTask myRequest = new myAsyncTask();
    myRequest.execute();

}


private class myAsyncTask extends AsyncTask<Void, Void, Void> {


    @Override
    protected void onPostExecute(Void result) {
        super.onPostExecute(result);
       // tv.setText(response);
    }

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
    }

    @Override
    protected Void doInBackground(Void... arg0) {

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        request.addProperty("number", "value");
        request.addProperty("user", "value");
        request.addProperty("pass", "value");

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.setOutputSoapObject(request);

        HttpTransportSE httpTransport = new HttpTransportSE(URL);

        httpTransport.debug = true;
        try {
            httpTransport.call(SOAP_ACTION, envelope);
        }catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (XmlPullParserException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } //send request
        SoapObject result = null;
        try {
            result = (SoapObject)envelope.getResponse();
        } catch (SoapFault e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        Log.d("App",""+result.getProperty(1).toString());
        String response = result.getProperty(1).toString();


        Log.e("result","0"+response);


        return null;
    }
}

我收到这些错误：
