Android SDK下載和更新失敗的解決方法

最近剛換了電腦，開始搭建Android開發環境的時候，下載SDK總是會出現如下錯誤：

1. Failed to fetch URL http://dl-ssl.google.com/android/repository/addons_list-1.xml.

據說dl-ssl.google.com在大陸被強了，偉大的天朝真是不讓人活了，解決方法就是修改C:\Windows\System32\drivers\etc\hosts文件。添加一行：

1. 74.125.237.1 dl-ssl.google.com

這裡需要注意的是hosts文件是只讀的，我們沒有權限修改，需要我們將hosts文件復制到桌面或者其他地方，然後修改，代碼如下：

1. # Copyright (c) 1993-2009 Microsoft Corp.
2. #
3. # This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
4. #
5. # This file contains the mappings of IP addresses to host names. Each
6. # entry should be kept on an individual line. The IP address should
7. # be placed in the first column followed by the corresponding host name.
8. # The IP address and the host name should be separated by at least one
9. # space.
10. #
11. # Additionally, comments (such as these) may be inserted on individual
12. # lines or following the machine name denoted by a '#' symbol.
13. #
14. # For example:
15. #
16. # 102.54.94.97 rhino.acme.com # source server
17. # 38.25.63.10 x.acme.com # x client host
19. # localhost name resolution is handled within DNS itself.
20. # 127.0.0.1 localhost
21. # ::1 localhost
22. //親，就是增加這一句哦
23. 74.125.237.1 dl-ssl.google.com

然後保存，復制修改後的hosts文件到C:\Windows\System32\drivers\etc 目錄，替換文件就好！！！我們再次下載SDK的時候就會成功啦，如下圖：

嘿嘿，大功告成啦！！！

PS：補充下，在mac或Linux中，hosts文件所在位置為/etc/hosts，可以使用sudo vim /etc/hosts來編輯。
