Solution 1

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!

Solution 2

Error solved:

just uninstalling build-tools 29.0.2 and reinstalling build-tools 29.0.2 in sdk manager android studio

thank you,

Solution 3

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.
