I spent like half a day solving this issue. For me flutter doctor displayed this error:

X Android SDK file not found: SomeLongPath/Android/sdk/build-tools/30.0.4-rc1/aapt

I just deleted this 30.0.4-rc1 folder because it was empty for some reason, ran flutter doctor and the issue is solved!

Thanks. saved a lot of my time. My installation of sdk 32.1.0-rc1 had failed due to network error. that's why the folder was empty. deleting that folder solved the issue. – Omkar76 May 10 '22 at 13:30

For my case and after wasting a full day. I was getting:

X Android SDK file not found: 
  C:\Users\user\AppData\Local\Android\sdk\build-tools\31.0.0-rc4\aapt.

So I copied C:\Users\user\AppData\Local\Android\sdk\build-tools\ path and pasted it in a folder directory path to navigate. I deleted a folder named 31.0.0-rc4 and run:

 flutter doctor -v

again. Hope someone gets helped.

Faced the same issue, on 'Android SDK version 31.0.0-rc4'. Tried to remove and reinstall build-tools. Didn't work. The problem was in the SDK tools folder. Removed both build-tools and tools folder. And then Installed Android SDK Command line tools, as well as, Android SDK Platform-tools again
