Question

Android新手，我的.Net webservices驻留在我的电脑上。当我的Android应用程序使用以下代码从模拟器调用web服务时（其中XX.XX.XX.XX是我的IP地址），它运行完美。

HttpClient client = new DefaultHttpClient();
                            HttpConnectionParams.setConnectionTimeout(client.getParams(), 1000000); //Timeout Limit
                        HttpResponse response;
                    try {
                        HttpPost post = new HttpPost("http://XX.XX.XX.XX/SDService_SAFTI/ServiceSD.svc/LoginUser");

但在移动设备上运行相同的代码不起作用。错误如下。这可能是港口问题吗？手机和PC都在同一个网络上。欢迎任何建议。非常感谢提前。

运行一段时间后，现在显示在logcat下面。

更新 - 屏幕截图 - 端口转发：

Answer 1

我这样做的方法是使用端口转发：

1）在移动设备和笔记本电脑浏览器上连接设备并打开Chrome。

2）在“URL”选项卡上，键入chrome：// inspect

3）单击端口转发并添加一个新行，端口为8888，IP为webservice_url：port。

4）现在在你的android应用程序代码中，用localhost：8888替换webservice_url：port。基本上现在8888你的手机将调用计算机webservice网址。注意：确保您的笔记本电脑和设备上都打开了Chrome。当你输入chrome：// inspect时，你应该能够看到你附加的设备。

有关更多帮助，请参阅此处：https://developer.chrome.com/devtools/docs/remote-debugging

同时将<uses-permission android:name="android.permission.INTERNET"/>添加到Androidmanifest.xml

Android手机没有连接到webservice但是模拟器连接 - 超时错误
