Error: "Android SDK does not have the proper build-tools."

[budha...@gmail.com]

I've installed Android Studio and added SDK packages as suggested in https://flutter.io/setup/#get-the-flutter-sdk and https://developer.android.com/studio/intro/update.html .

But when I run

flutter doctor

, I get the following error:

[✓] Flutter (on Linux, channel alpha)
    • Flutter at /home/budhajeewa/Apps/flutter
    • Framework revision 6d2d495369 (3 weeks ago), engine revision a943c732d5


[-] Android toolchain - develop for Android devices
    • Android SDK at /usr/lib/android-sdk
    x Android SDK does not have the proper build-tools.
    • Try re-installing or updating your Android SDK.


[✓] Atom - a lightweight development environment for Flutter
    • flutter plugin version 0.2.3
    • dartlang plugin version 0.6.28

Any idea why?

Looks like we print that message when we can't find any SDK versions:

    if (sdkVersions.isEmpty || latestVersion == null)

      return <String>['Android SDK does not have the proper build-tools.'];

What directories do you have in the "platforms" subdirectory of the Android SDK?  For example, on my Mac, here's what I've got:

$ ls ~/Library/Android/sdk/platforms/

android-24

I remember (On mobile now.) choosing "~/Apps/Android/Sdk" directory when installing Android Studio, so, probably a "platforms" directory inside that is having those platform tools.

Do we have to set that path somewhere?

We try several of the common paths.  If you have the SDK in an odd location, you can use the ANDROID_HOME environment variable to tell the tool where to find it.

However, in your case, I think the tool is able to find the Android SDK because otherwise it would have given you a different message.  Maybe you have an old copy of the SDK at the usual location that is incomplete?

Well, I installed these only today, so I think I should have latest versions.

In my "~/Apps/Android/Sdk/platforms/" directory, there are "android-22" and "android-22" directories.

What happens if you set ANDROID_HOME to $HOME/Apps/Android/Sdk and then try flutter doctor?

$ export ANDROID_HOME=$HOME/Apps/Android/Sdk

$ flutter doctor

Now I feel stupid.

That works!

Googol thanks!

IMHO, the bug here is that the error message the tool gave you wasn't very informative.  We'll work on improving the message so that folks who encounter the same situation in the future have a better experience.

Thanks!

Thank *you*!

Your solution is very good. A FAQ would be helpful too!
