I already have Android Studio installed and tried installing Flutter. After following the instructions, I have encountered a problem. When I run

flutter doctor -v

It returns

I tried connecting my device too and it didn't recognize, even after enabling USB debugging. I also tried reinstalling Android Studio. I think the issue lies with the missing 'aapt' since it's not on any folder when i manually looked for it but Android SDK file not found: C:\Users\%User%\AppData\Local\Android\sdk\build-tools\30.0.2\aapt tells me it should be there.

Thank you for the help!

    It still didn't work. I think the issue lies with the missing 'aapt' since it's not on any folder when i manually looked for it. Android SDK file not found: C:\Users\%User%\AppData\Local\Android\sdk\build-tools\30.0.2\aapt tells me it should be there. – Blooming Oct 02 '20 at 06:54
  • check you android sdk, like i have android sdk in "D:\android_sdk\". i think you given path "C:\Users\%User%\AppData\Local\Android\sdk\build-tools\30.0.2\aapt", this path is wrong. I run above command like " flutter config --android-sdk D:\android_sdk\" – pratik vekariya Oct 02 '20 at 11:25

I had the same problem today :

[!] Android toolchain - develop for Android devices (Android SDK version 30.0.3) X Android SDK file not found: C:\Users\admin\AppData\Local\Android\Sdk\build-tools\30.0.3\aapt.

I fixed it by deleting the two most recent folders in C:\...\build-tools\ which do not contain aapt.exe -> 30.0.2 and 30.0.3 (This deleted folders only contained a folder named .installer).

That's not a big deal. You install the Android SDK and 1 notice that the device is not connected only. You can install the android SDK from the link below:

https://developer.android.com/studio#downloads

  • You double-check the path to the SDK file to see if it is correct? You just need to install the SDK file as below. Here is my path: /Users/admin/Library/Android/sdk – Souvenir Oct 02 '20 at 07:26

I had the same issue Android SDK file not found: C:\Users\Admin\AppData\Local\Android\Sdk\build-tools\31.0.0\aapt.

I had already tried other solutions but this worked for me . In SDK Manager , go to SDK tools , and check the checkbox "Show the various packages" and uncheck "Hide obsolete packages"

Now under Android SDK Build-tools 31 , install 31.0.0 and apply Under Android SDK Command-line tools (latest), install Android SDK Command-line tools (obsolete)

This worked for me , hope it works for you too !

Reinstalling the sdk 30.0.2 from sdk manager in android studio(Tools->sdk tools->(tick show package details)) fixes the problem.
