原因是谷歌被墙了
修改hosts文件，Windows： C:\WINDOWS\system32\drivers\etc； Linux： /etc/hosts。 添加 #Google首页 203.208.46.146 www.google.com #方便查看android api，下载sdk等 74.125.113.121 developer.android.com #sdk manger下载 203.208.46.146 dl.google.com 203.208.46.146 dl-ssl.google.com
光是这样还是不行的，因为使用https下载，
需要在sdk manger菜单栏tools--options--勾上Force https xxx to be http xxx。
