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

Answer 4

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 folder named 31.0.0-rc4 and run

flutter doctor -v again. hope someone gets helped

Answer 5

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!
