Android SDK下载和更新失败的解决方法

今天更新sdk，遇到了更新下载失败问题：

Fetching https://dl-ssl.google.com/android/repository/addons_list-2.xml
Fetched Add-ons List successfully
Fetching URL: https://dl-ssl.google.com/android/repository/repository-8.xml
Done loading packages.

搜索了下，解决方案如下：

解决国内访问Google服务器的困难：
1.启动 Android SDK Manager ；
2.打开主界面，依次选择「Tools」、「Options...」，弹出『Android SDK Manager - Settings』窗口；
3.在『Android SDK Manager - Settings』窗口中，在「HTTP Proxy Server」和「HTTP Proxy Port」输入框内填入mirrors.neusoft.edu.cn和80，并且选中「Force https://... sources to be fetched using http://...」复选框；4.设置完成后单击「Close」按钮关闭『Android SDK Manager - Settings』窗口返回到主界面；
5.依次选择「Packages」、「Reload」。

如此，问题解决~
