I used Android Studio some years ago. After that time I initialized Windows 10 once and used the migration tool to change my SSD. This time, I needed Android Studio once more for making a Flutter app, but it was gone(I don't remember removing it myself).

几年前我用过Android Studio。在那之后，我对Windows10进行了一次初始化，并使用迁移工具更换了我的固态硬盘。这一次，我再次需要Android Studio来制作一款Ffltter应用程序，但它不见了(我不记得自己把它移走了)。

So I installed Android Studio once more and Flutter once more.
But after I make a new flutter project by Android Studio, I can see a blue ribbon at the top of the editor that says 'Android SDK "Android API 29 Platform" is not found on the disk or corrupted.'

所以我又一次安装了Android Studio，又一次飞来飞去。但在我用Android Studio制作了一个新的Ffltter项目后，我可以看到一个蓝丝带出现在编辑器的顶部，上面写着“Android SDK”Android API 29 Platform“未在磁盘上找到或未损坏。”

I try something to solve that. :

我试着想办法解决这个问题。：

• Install Android API 29(Android 10.0("Q")) with the Android SDK manager = not works


• Click the Configure...(on the blue ribbon) and Click "Download Android SDK" and go on = not works


• Uninstall the Andriod Studio with uninstaller(remove all settings) and remove all of the left(%userprofile%.gradle, appdata\local\Android, program files\Android) of it and reinstall Android Studio = not works

Everything is not working. I found one who has a problem like me, but Its solution is not work for me.

并不是所有的事情都在起作用。我找到了一个和我一样有问题的人，但它的解决方案对我不起作用。

To fix the problem, I installed a previous version of Android Studio [Electric Eel | 2022.1.1 Patch 2] from Android Studio Archives which worked fine and I never saw that error again.

我有Android Studio[长颈鹿|2022.3.1补丁1]，当你尝试下载它时，它是目前最新的稳定版本。我不确定这是不是那个版本的错误，或者是什么，但这为我修复了它。

It is a problem with New UI Android Studio I assume. The fix is very easy, just turn off Enable new UI in File->Settings->Appearance & Behavior->New UI. After that restart Android Studio and then turn on Enable new UI and restart again.

我想这是新用户界面Android Studio的一个问题。修复非常简单，只需在文件->设置->外观和行为->新用户界面中关闭启用新用户界面。之后，重启Android Studio，然后打开启用新用户界面，然后再次重启。

The error should be gone by now.

错误现在应该已经消失了。

I had two separate Android Studio installs upgraded to 2022.3.1 Giraffe, and both had their Android SDKs corrupted as a result.

我有两个单独的Android Studio安装升级到了2022.3.1 Giraffe，结果都被破坏了Android SDK。

The only solution that consistently worked was deleting the Android SDK folder and redownloading everything from scratch (in my case for Android API 34) using Tools -> SDK Manager.

唯一一直有效的解决方案是删除Android SDK文件夹，然后使用工具->SDK管理器从头开始重新下载所有内容(在我的例子中是Android API 34)。

Delete everything related to Android Studio (Android, .jdk and other AS related folders ) including the app itself and download the Android Studion from ToolBox
That will solve your problem.

删除与Android Studio相关的所有内容(Android、.jdk和其他相关文件夹)，包括应用程序本身，并从工具箱中下载Android Studion，以解决您的问题。

Most probably you have to download the Android SDK tool (Obsolete) from the SDK Manager

很可能你必须从SDK管理器下载Android SDK工具(已过时)
