Update for SDK Manager under MacBook [it doesn't matter if Google is blocked]

Talk less, just say the procedure:

1. Modify the/etc/hosts file:

Right-click the Finder, select Go to Folder, enter/private/etc/, hit enter, the file/etc/hosts copy to the desktop (because the permissions are limited, can not be directly modified), the file after the fight to add content:

#Google主页
203.208.46.146 www.google.com
#这行是为了方便打开Android开发官网 don't seem to be able to open a VPN now.
74.125.113.121 developer.android.com
#更新的内容从以下地址下载
203.208.46.146 dl.google.com
203.208.46.146 dl-ssl.google.com

After the modification, replace the original file.

2. Force the use of the HTTP protocol:

Eclipse, Punch-in top menu bar window-->android SDK Manager, then action top menu bar Android SDK manager-->preferences--> tick Force https:// ......

By completing the two steps above, you can update the SDK Manager you need.

Another: In the Windows Environment Update method Similar, there are many tutorials online, direct search can. Because there are very few tutorials on the MacBook, I hereby explain.
