[置顶] Android 系列：安装Android SDK出现Failed to fetch URL http://dl

最近有一个项目要用安卓开发，记得以前装过Android SDK，今天照例。先下载Eclipse，又装好了ADT，可是在装Android SDK时却出现了
Fetching http://dl-ssl.google.com/android/repository/addons_list-1.xml
Failed to fetch URL http://dl-ssl.google.com/android/repository/addons_list-1.xml, reason: Connection to http://dl-ssl.google.com/ refused
Fetched Add-ons List successfully
Fetching URL: http://dl-ssl.google.com/android/repository/repository-6.xml
Failed to fetch URL http://dl-ssl.google.com/android/repository/repository-6.xml, reason: Connection to http://dl-ssl.google.com/ refused
Done loading packages.

      网上查资料，终于在谷歌官网找到了答案

      具体操作：
•用记事本或Gvim打开C:\WINDOWS\system32\drivers\etc中的hosts文件
•在最后一行添加74.125.237.1 dl-ssl.google.com
•成功解决问题。
