消除SDK更新时的“https://dl-ssl.google.com refused”异常

消除SDK更新时，有可能会出现这样的错误： Download interrupted: hostname in certificate didn't match: <dl-ssl.google.com> != <www.google.com> Download interrupted: Connection to https://dl-ssl.google.com refused Done. Nothing was installed.   解决办法是：将https://修改为http:// 修改方法是：如下图，在Android SDK Manager->Tools-Options...选项界面， 将“Force https://… sources to be fetched using http://…”勾选！
