未找到 Flutter Android SDK 文件

Question

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!

Answer 2

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 ).

Answer 3

flutter config --android-sdk

run this command and run flutter doctor again this should help you

Answer 4

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

Answer 5

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 !

Answer 6

在 android studio(Tools->sdk tools->(tick show package details)) 中从 sdk manager 重新安装 sdk 30.0.2 解决了这个问题。

Answer 7

I had the same problem today. In my problem, can not find 32 aapt., I had try many:

1. flutter config --android-sdk [path]
2. uninstall 32 and install again
3. install low version like 31（30）
4. and so on

still not work until:

1. uninstall 32
2. remove folder 32 which need aapt.
