Transport endpoint is not connected

java.net.SocketTimeoutException: Transport endpoint is not connected

个人解决方法是：将xxx.openConnection()改成以下代码：

01	HttpURLConnection conn = null;

02	String host = android.net.Proxy.getDefaultHost();

03	if (host != null) {

04	int port = android.net.Proxy.getDefaultPort();

05	SocketAddress vAddress = new InetSocketAddress(host, port);

06	java.net.Proxy vProxy = new java.net.Proxy(java.net.Proxy.Type.HTTP, vAddress);

07	conn = (HttpURLConnection) downUrl.openConnection(vProxy);

08

} else {

09	conn = (HttpURLConnection) downUrl.openConnection();

10

}

随后解决了这个问题
