前言
最近更新完 Android Studio 之后，发现莫名其妙的经常很卡。通过任务管理器查看Studio竟然一直持续CPU使用率在95%以上， What the Fk！！
什么情况啊！
首先确认，当前Studio没有运行下载，没有打包，没有开模拟器，也没什么正在执行的任务。
最后找了半天发现 Analysis.. 在持续运行。。。
很疯狂的运行。。。

解决办法
-
升级或者重装 Android Studio
这是万能大法。
然而，我还是想弄明白为啥，所以还没急着升级，先观察一波。
文尾有下载地址。
注：下载地址为谷歌中文开发者社区，非营销，非推广！
有人遇到说是 org.jetbrains.kotlin 的问题
这个是在 Stack Overflow 中看到的。
提问者也是卡住了，通过升级 org.jetbrains.kotlin 解决问题。
如文章尾部的参考链接。
我尝试了一下，会好转。
我的 kotlin 从 1.6.0 升级到了 1.6.10。
虽然显示 Performing Analysis，但是确实不会反复执行了，只是感觉似乎一直未执行完毕。Flie >> Invalidate Caches/Restart >> Invalidate Caches/Restart
可能是 plugins 插件出现了问题。
这里可以考虑清除 Studio 缓存，然后重启。
这招也接近万能大法了。
可以解决很多类似问题。删除缓存 c:/Users/me/AppData/Local/Google/AndroidStudio4.2 (win10)
这条也是在 Stack Overflow 中看到的。点我看
不过这篇中更多的推荐是修改Kotlin版本
不过也可以作为一种尝试记录，都不行的时候，可以试试删这个缓存
个人尝试
由于我是kotlin升级和 Invalidate Caches/Restart 同时做的，不太确定哪个具体生效的。
个人倾向是后者，错误原因可能还是插件的问题。
其它
日志错误尚未分析。
