android怎麼訪問天氣webservice，用網上找的連接都不行啊

====================問題描述==================== 作個天氣預報的小測試用網上找的連接怎麼不行，有作過的指導下。感激涕零！！  求用法或可用連接！！！！！！！！！！ http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx  和  http://www.webxml.com.cn/webservices/weatherwebservice.asmx  都是不行的！跟着網上例子作的。  錯誤：  11-13 19:27:10.545: W/System.err(29917): java.net.UnknownHostException: Unable to resolve host "webservice.webxml.com.cn": No address associated with hostname  11-13 19:27:10.545: W/System.err(29917):  at java.net.InetAddress.lookupHostByName(InetAddress.java:426)  11-13 19:27:10.545: W/System.err(29917):  at java.net.InetAddress.getAllByNameImpl(InetAddress.java:242)  11-13 19:27:10.545: W/System.err(29917):  at java.net.InetAddress.getAllByName(InetAddress.java:220)  11-13 19:27:10.545: W/System.err(29917):  at libcore.net.http.HttpConnection.<init>(HttpConnection.java:71)  11-13 19:27:10.545: W/System.err(29917):  at libcore.net.http.HttpConnection.<init>(HttpConnection.java:50)  11-13 19:27:10.545: W/System.err(29917):  at libcore.net.http.HttpConnection$Address.connect(HttpConnection.java:351)  11-13 19:27:10.545: W/System.err(29917):  at libcore.net.http.HttpConnectionPool.get(HttpConnectionPool.java:86)  11-13 19:27:10.545: W/System.err(29917):  at libcore.net.http.HttpConnection.connect(HttpConnection.java:128)  11-13 19:27:10.545: W/System.err(29917):  at libcore.net.http.HttpEngine.openSocketConnection(HttpEngine.java:308)  11-13 19:27:10.545: W/System.err(29917):  at libcore.net.http.HttpEngine.connect(HttpEngine.java:303)  11-13 19:27:10.545: W/System.err(29917):  at libcore.net.http.HttpEngine.sendSocketRequest(HttpEngine.java:282)  11-13 19:27:10.545: W/System.err(29917):  at libcore.net.http.HttpEngine.sendRequest(HttpEngine.java:232)  11-13 19:27:10.545: W/System.err(29917):  at libcore.net.http.HttpURLConnectionImpl.connect(HttpURLConnectionImpl.java:80)  11-13 19:27:10.545: W/System.err(29917):  at org.ksoap2.transport.ServiceConnectionSE.connect(ServiceConnectionSE.java:46)  11-13 19:27:10.545: W/System.err(29917):  at org.ksoap2.transport.HttpTransportSE.call(HttpTransportSE.java:68)  11-13 19:27:10.550: W/System.err(29917):  at com.testtv.core.WeatherActivity.getWeather(WeatherActivity.java:102)  11-13 19:27:10.550: W/System.err(29917):  at com.testtv.core.WeatherActivity$2$1.run(WeatherActivity.java:76) 11-13 19:27:10.550: W/System.err(29917):  at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1076)  11-13 19:27:10.550: W/System.err(29917):  at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:569)  11-13 19:27:10.550: W/System.err(29917):  at java.lang.Thread.run(Thread.java:856)  11-13 19:27:10.550: W/System.err(29917): Caused by: libcore.io.GaiException: getaddrinfo failed: EAI_NODATA (No address associated with hostname)  11-13 19:27:10.550: W/System.err(29917):  at libcore.io.Posix.getaddrinfo(Native Method) 11-13 19:27:10.550: W/System.err(29917):  at libcore.io.ForwardingOs.getaddrinfo(ForwardingOs.java:55)  11-13 19:27:10.550: W/System.err(29917):  at java.net.InetAddress.lookupHostByName(InetAddress.java:411)     代碼：  package com.testtv.core;  import java.io.UnsupportedEncodingException;
