android sdk下载和更新失败的解决方法

android sdk下载和更新失败的解决 Android SDK 下载和更新失败的解决方法～～～ 最近刚换了电脑，开始搭建Android开发环境的时候，下载SDK总是会出现如下错误: [java] view plaincopyprint? 1. Failed to fetch URL 据说dl-ssl.google.com在大陆被强了，伟大的天朝真是不让人活了，解决方法就是修改 C:\Windows\System32\drivers\etc\hosts文件。添加一行: [java] view plaincopyprint? 1. 74.125.237.1 dl-ssl.google.com 这里需要注意的是hosts文件是只读的，我们没有权限修改，需要我们将hosts文件复制到桌面 或者其他地方，然后修改，代码如下: [java] view plaincopyprint? 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 18. 19. # localhost name resolution is handled within DNS itself. 20. # 127.0.0.1 localhost 21. # ::1 localhost 22. //亲，就是增加这一句哦 23. 74.125.237.1 dl-ssl.google.com 然后保存，复制修改后的hosts文件到C:\Windows\System32\drivers\etc 目录，替换文件就 好～～～我们再次下载SDK的时候就会成功啦，如下图: 嘿嘿，大功告成啦～～～ PS:补充下，在mac或Linux中，hosts文件所在位置为/etc/hosts，可以使用sudo vim /etc/hosts来编辑。 转至:超牛的一个博主
