android sdk manager不能更新

Eclipse输出错误reason: Connection to https://dl-ssl.google.com refused
估计这又是伟大GFW的功劳，我们只需要配置一下hosts文件，在文件的末尾添加下面一句：
74.125.237.1 dl-ssl.google.com


windows系统中hosts文件的位置为：C:\Windows\System32\drivers\etc ，找到该文件并已文本形式打开，添加上面一句话，保存之后关闭，重启Eclipse打开Android SDK Manager，ok！

把如下的内容复制保存为hosts,然后替换掉 C:\Windows\System32\drivers\etc\目录下的 hosts，就可以方便的使用google.com啦
