Q：码云打不开，怎么办？
A：
第一步：
找到hosts文件，文件目录：C:\Windows\System32\drivers\etc
部分电脑该目录下可能没有hosts文件，可以从其他电脑拷一份过来。如果提示无法修改，请使用管理员权限打开文件。
第二步：
修改hosts，添加内容：212.64.62.174 gitee.com
第三步：
浏览器打开码云官网：gitee.com，刷新，搞定！

Q:Android Studio 4.1 版本 不适配butterknife的问题
1、方案一：删除AppData\Roaming\Google\AndroidStudio4.1\plugins下面的插件。更换插件Android-ButterKnife-Injections.jar，不用android-butterknife-zelezny.jar。
2、如果方案一不成功：更换安装路径，Android-ButterKnife-Injections.jar放在系统的安装路径下：D:\Android\androidstudio\plugins。重启AS试试。代码也不白了。
