尝试在 Android 中调用 WCF 方法，它在 androidHttpTransport.call(...) 处停止，一段时间后，由于无法连接到服务器而超时。以下是代码：

我的安卓代码：

    public class MainActivity extends Activity {
private static final String NAMESPACE = "http://try1.com/";
private static final String METHOD_NAME = "ObtainAnswerToQuestion";
private static final String SOAP_ACTION = "http://bcaa.com/IEightBall/ObtainAnswerToQuestion";
private static final String URL = "http://10.0.2.2:8080/MagicEightBallService";
Button submit;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    submit = (Button)this.findViewById(R.id.submit);
    submit.setOnClickListener(new Button.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);                      
            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);                   
            envelope.dotNet = true;
            PropertyInfo info = new PropertyInfo();
            info.setName("Question");
            info.setType("Bylawme".getClass());
            info.setValue("BB2233asdsa");
            request.addProperty(info);
            envelope.setOutputSoapObject(request); 
            new LongProcess().execute(envelope);
        }  
    }); 
}
 private class LongProcess extends AsyncTask<Object, Void, Boolean> {

        @Override
        protected Boolean doInBackground(Object... param) {
            HttpTransportSE androidHttpTransport = new HttpTransportSE(URL,30000);
            SoapSerializationEnvelope envelope = (SoapSerializationEnvelope) param[0];
            try {
                androidHttpTransport.call(SOAP_ACTION, envelope);
                SoapPrimitive result = (SoapPrimitive) envelope.getResponse();
                // to get the data
                String resultData = result.toString();
                submit.setText(resultData);
            } catch (Exception ex) {
                submit.setText(ex.getMessage());
            }
            return true;
        }      
        @Override
        protected void onPostExecute(Boolean result) {  
        }
        @Override
        protected void onPreExecute() {
        }
        @Override
        protected void onProgressUpdate(Void... values) {
        }
    }
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}
    }

任何帮助将不胜感激。

已解决问题。这是因为2个问题：

（1）从这个论坛的另一个问题中找到了这个解决方案（现在找不到......）：

require to kill a connection when not in use, by adding in the following code

    System.setProperty("http.keepAlive", "false");

并通过在

androidHttpTransport.call(...):
        androidHttpTransport.getServiceConnection().setRequestProperty("Connection","Keep-Alive");

(2) 不应该answer.setText(...)在LoopProcess线程中调用。所以只需要将值返回给主线程来设置值。

和中提琴它的作品，终于！
