Android Studio

前言

最近更新完 Android Studio 之后，發現莫名其妙的經常很卡，通過任務管理器查看Studio竟然一直持續CPU使用率在 95% 以上， What the Fk！！

什么情況啊！

首先確認，當前Studio沒有運行下載，沒有打包，沒有開模擬器，也沒什么正在執行的任務，
最后找了半天發現 Analysis… 在持續運行，，，
很瘋狂的運行，，，

解決辦法

• 升級或者重裝 Android Studio
  這是萬能大法，
  然而，我還是想弄明白為啥，所以還沒急著升級，先觀察一波，
• 有人遇到說是 org.jetbrains.kotlin 的問題
  這個是在 Stack Overflow 中看到的，
  提問者也是卡住了，通過升級 org.jetbrains.kotlin 解決問題，
  如文章尾部的參考鏈接，
  我嘗試了一下，會好轉，
  我的 kotlin 從 1.6.0 升級到了 1.6.10，
  雖然顯示 Performing Analysis，但是確實不會反復執行了，只是感覺似乎一直未執行完畢，
• Flie >> Invalidate Caches/Restart >> Invalidate Caches/Restart
  可能是 plugins 插件出現了問題，
  這里可以考慮清除 Studio 快取，然后重啟，
  這招也接近萬能大法了，
  可以解決很多類似問題，

個人嘗試

由于我是kotlin升級和快取清除同時做的，不太確定哪個具體生效的，
個人傾向是后者，錯誤原因可能還是插件的問題，

其它

日志錯誤尚未分析，
有相關經驗的大佬可以在評論區指導一下，
