NetworkOnMainThreadException Android中 [英] NetworkOnMainThreadException in Android

问题描述

我有这样的例外。我怎样才能做到这一点使用线程的概念？

I have this exception. How can I do this using Threading concept?

public class WebService extends AsyncTask<String, String, String>{

    private final String NAMESPACE ="http://tempuri.org/";//"http://localhost:9583/YP_Android_WebService/YP_Android_WebService.asmx";//
    private final String URL ="http://10.0.2.2:1243/YP_Android_WebService/YP_Android_WebService.asmx?WSDL";

    public boolean checkUser(String _EmailID, String _Password) {

         boolean result = false; 

        final String SOAP_ACTION ="http://tempuri.org/checkUser";//"http://localhost:9583/YP_Android_WebService/YP_Android_WebService.asmx/checkUserLogin";//
        final String METHOD_NAME = "checkUser";

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

        PropertyInfo propertyInfoEmail = new PropertyInfo();
        propertyInfoEmail.setName("_EmailID");
        propertyInfoEmail.setValue(_EmailID);
        propertyInfoEmail.setType(String.class);
        request.addProperty(propertyInfoEmail);

        PropertyInfo propertyInfoPassword = new PropertyInfo();
        propertyInfoPassword.setName("_Password");
        propertyInfoPassword.setValue(_Password);
        propertyInfoPassword.setType(String.class);
        request.addProperty(propertyInfoPassword);

         final SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
            envelope.dotNet = true; // put this only if the web service is .NET one
            envelope.setOutputSoapObject(request);
            final HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

        try {


            androidHttpTransport.call(SOAP_ACTION, envelope);
            SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
            Log.i("myApp", response.toString());
            if(response.toString().equalsIgnoreCase("true")){
                result = true;
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return result;
    }
}

的异常是在这一点上。

The Exception is at this point.

androidHttpTransport.call（SOAP_ACTION，信封）; TI抛出
  NetworkonMainThread异常。

androidHttpTransport.call(SOAP_ACTION, envelope); ti throws NetworkonMainThread Exception.

任何一个可以帮助我做到这一点使用线程概念

Can any one help me to do this using Thread concept

推荐答案

您没有使用的AsyncTask 正常。你有没有实现的方法。你要做的所有的网络/数据库操作中的 doInBackground（）方法，并作为@Dirk说，在UI中的 onPostExecute（）方法。

You are not using the Asynctask properly. You have unimplemented methods. You have to do all the Network / Database operations in the doInBackground() method, and as @Dirk said, UI in the onPostExecute() method.

这教程也非常有助于你理解 AsyncTasks 并了解更多有关主题。

This tutorial is also very helpful for you to understand AsyncTasks and learn more about Threads.
