消除SDK更新時(shí)，有可能會(huì )出現這樣的錯誤： 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.   解決辦法是：將https://修改為http:// 修改方法是：如下圖，在A(yíng)ndroid SDK Manager->Tools-Options...選項界面， 將“Force https://… sources to be fetched using http://…”勾選！
