Android客戶端解析web伺服器XML資料

通過Pull 解析方式實現

程式碼如下：

java.net.ConnectException: failed to connect to /127.0.0.1 (port 8062) after 8000ms: isConnected failed: ECONNREFUSED (Connection refused)

加上許可權檢視程式碼找了很久發現不了原因,經過顯示測試，原來是訪問不到這個頁面

但是在電腦上面是可以訪問到的

查了下搜尋引擎原來要保證兩者之間處於同一網段

好像是模擬器可以用10.0.2.2代替

我用的真機測試要改為ip地址就沒有報錯了。

localhost或者127.0.0.1是不能訪問的，會報以上這個錯誤。
