Flutter doctor error - Android sdkmanager tool not found. Windows

Question

I have been going round in circles with this issue, there are so many that people have issues similar to mine, but not one of them is the same. I am trying to get flutter fully set up, but can't resolve one of the issues.

When I run flutter doctor -v I get the following output:

[√] Flutter (Channel stable, v1.12.13+hotfix.8, on Microsoft Windows [Version 10.0.18362.657], locale en-GB)     • Flutter version 1.12.13+hotfix.8 at C:\flutter     • Framework revision 0b8abb4724 (3 weeks ago), 2020-02-11 11:44:36 -0800     • Engine revision e1e6ced81d     • Dart version 2.7.0  [!] Android toolchain - develop for Android devices (Android SDK version 29.0.3)     • Android SDK at C:\Users\%username%\AppData\Local\Android\Sdk     • Android NDK location not configured (optional; useful for native profiling support)     • Platform android-29, build-tools 29.0.3     • Java binary at: C:\Program Files\Android\Android Studio\jre\bin\java     • Java version OpenJDK Runtime Environment (build 1.8.0_212-release-1586-b04)     X Android license status unknown.

And if I try to run the command flutter doctor --android-licenses I get:

Android sdkmanager tool not found (C:\Users%username%\AppData\Local\Android\Sdk\tools\bin\sdkmanager). Try re-installing or updating your Android SDK, visit https://flutter.dev/setup/#android-setup for detailed instructions.

And it's right, there is no "tools" folder in my SDK folder. How on earth do I fix that! I have installed all the SDK tools, even the NDK (not that flutter picks that up) I have tried creating a tools folder and copying sdkManager.bat (including the bin folder) from build-tools, but that just tells me to update my SDK manager, which when attempted just fails.

It looks like everything still works, it just makes me a little uncomfortable having that issue there.

Any help is much appreciated.

Answer 1

Android toolchain - develop for Android devices X cmdline-tools component is missing Run path/to/sdkmanager --install "cmdline-tools;latest"

This error means your "Android SDK Command-line Tools are missing"

1. Open Android Studio
2. In the Menu bar , click Tools(4th last)
3. choose SDK Tools panel
4. Tick Android SDK Command-line Tools
5. Click Apply at bottom of the window

IT WILL START DOWNLOADING the missing component

Answer 2

I have just hit the same issue - my resolution was a little simpler:

Just like you, I have Android Studio installed, the key is to install Android SDK Command-line Tools, steps being:

1. Open Android Studio
2. Tools Menu, SDK Manager
3. In the window that comes up there are inner panels, choose SDK Tools panel
4. Tick Android SDK Command-line Tools
5. Choose Apply button near the bottom of the window

At that point, you will be prompted to accept the SDK license and the command line tools will be installed. Your license issue should now be resolved.

FYI, the command line tools will add a new folder cmdline-tools inside your SDK Folder. If you look in there cmdline-tools/latest/bin you will see sdkmanager - but your license issue should already be resolved.
