[SDK Manager] 拒绝访问 并且无法下载更新

eclipse中启动sdk manager 会报错：

找到sdk的位置，比如我是E:\zhangbin\Android\android-sdk

然后sdk manager右键管理员权限打开，就ok了。

===

sdk启动后，无法下载，显示 SDK Manager总是被google的服务器拒绝；

 SDK Manager->Tools栏->Options，
勾选“Force https://… sources to be fetched using http://…”，强制使用http协议。

强制使用http代替https也不行，

依旧被拒绝。

参考 http://blog.sina.com.cn/s/blog_8a7de0b20101c8r1.html

在C:\Windows\System32\drivers\etc的hosts中，加入

#google_android更新
203.208.46.146 dl.google.com
203.208.46.146 dl-ssl.google.com

马上就可以了。
