今天更新sdk，遇到了更新下載失敗問題：

搜索了下，解決方案如下：

解決國內訪問Google服務器的困難：

1.啓動 Android SDK Manager ；

2.打開主界面，依次選擇「Tools」、「Options...」，彈出『Android SDK Manager - Settings』窗口；

3.在『Android SDK Manager - Settings』窗口中，在「HTTP Proxy Server」和「HTTP Proxy Port」輸入框內填入

mirrors.neusoft.edu.cn和80，並且選中「Force https://... sources to be fetched using http://...」複選框；4.設置完成後單擊「Close」按鈕關閉『Android SDK Manager - Settings』窗口返回到主界面；

5.依次選擇「Packages」、「Reload」。
