Android应用程序-套接字异常：操作超时

Question

我正在编写一个 Android 客户端，它通过网络服务使用来自服务的一些数据。在模拟器上运行应用程序时，一切都很好。现在我想在真实设备上测试我的应用程序。服务器目前正在本地运行。登录失败。

这是我的登录信息：

// Anfrage Login
    HttpPost requestLogin = new HttpPost(PathContainer.loginURL);
    HttpResponse response = null;

    // Parameter fuer Post Anfrage an die URL spring_security_check
    // Name und Password werden uebergeben
    // Login wie in Browser
    List<NameValuePair> params = new ArrayList<NameValuePair>();
    params.add(new BasicNameValuePair("j_username", username));
    params.add(new BasicNameValuePair("j_password", password));

    // LOGIN
    // Fuegt Parameter (Name und Password) der URL hinzu
    try {
        requestLogin
                .setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    HttpHost proxy = new HttpHost("192.168.1.116", 8080);
    c.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);

    try {
        response = c.execute(requestLogin);
    } catch (ClientProtocolException e1) {
        e1.printStackTrace();
    } catch (IOException e1) {
        e1.printStackTrace();
    }

以前有人遇到过这个问题或者可能有一些想法吗？

您能否确认您的设备网络无线电已打开并且可以通过 Wi-Fi 或 GS​​M 无线电连接到您的服务器？
