源尝试该 url 连接并尝试登录，但我无法登录。只是...再次登录读取流源屏幕... main.java（某些部分）

public class Main extends SherlockActivity {
   ........

    public class async_Login extends AsyncTask<String, Void, String> {
        @Override
        protected String doInBackground(String... params) {
            try {
                // URL setting
                communion_Url = new URL("http://communion.gntc.net/Default.aspx");
                connection = (HttpURLConnection) communion_Url .openConnection();

                // <Form> setting
