Flutter doctor error - Android sdkmanager tool not found. Windows

Question

I have been going around in circles with this issue, there are so many people who 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:

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.

Resolving Flutter Android SDK Installation Issues on macOS

I encountered a problem where the Android SDK would not reinstall due to the presence of old SDK files at /Users/{my_user_name}/Library/Android/sdk. To address this issue on macOS where the Library directory is hidden, here are the steps I followed:

1. Reveal Hidden Files in Finder:

   • Open a Finder window.
   • Press Command + Shift + . (dot) to toggle the visibility of hidden files and folders.

2. Remove the Old SDK Directory:

   • Navigate to /Users/{my_user_name}/Library/Android/sdk.
   • Delete this directory to remove the old SDK files.

3. Reinstall Android SDK Command-line Tools:

   • Open Android Studio.
   • Go to Settings -> Android SDK, or Languages & Frameworks -> Android SDK.
   • In the SDK Tools tab, check Android SDK Command-line Tools (latest) which should have the status 'Not Installed'.
   • Click Apply to start the installation.

4. Accept Android Licenses:

   • Open Terminal (use Cmd + Space and type Terminal).
   • Run flutter doctor --android-licenses and accept the licenses as prompted.

5. Restart Android Studio:

   • Close and reopen Android Studio. It should initiate the SDK installation. Accept any prompts if required.

6. Verify the Flutter Setup:

   • In Terminal, run flutter doctor.
   • It should now display "No issues found!"

If you have sdkmanager in the env, you can run the command:

sdkmanager --install "cmdline-tools;latest"

If it is not defined as an environment variable, you can go to the sdkmanager folder and run it there. It would be something like this below:

/home/User/path-Android/cmdline-tools/bin/sdkmanager --install "cmdline-tools;latest"

And then just run flutter's doctor again.

Answer 3

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 4

Run 'flutter config --android-'flutter config --android-sdk <path-to/android/sdk>sdk <path-to/android/sdk>

Answer 5

Open sdk manager from here

Navigate to the panel titled "SDK Tools"

Then, select **Android Sdk Command-line Tools
Note: If it's already checked then follow the process

• Uncheck
• Apply
• Re-check
• Apply

Answer 6

It's almost 2022, and things seem changed a little bit.

I had my SDK installed on a separate folder and command-line tools were missing. even though I downloaded and extracted it into the SDK folder this error was still there. took me sometime to figure it out.

• make sure to have correct sdk path. use this if needed flutter config --android-sdk <path-to-your-android-sdk-path>
• download latest command-line tools from developer.android.com
• extract downloaded file's content into the SDK folder and make sure it has the following structure

<sdk folder>/cmdline-tools/latest/`
 |- bin
 |- lib
 |- ...

---

Alternatively, use the following command from any directory of command-line tools you have: <cmdline-tools folder>\bin\sdkmanager --install "cmdline-tools;latest" --sdk_root=<sdk folder>

this may however need you to have relatively new sdkmanager to do the job. so it may not give you expected result if it is too old.

---

PS: it is not working if the content is under <sdk folder>/tools, <sdk folder>/cmdline-tools or <sdk folder>/cmdline-tools/tools

I have noticed when running android studio from commandline:

Observed package id 'build-tools;32.0.0-rc1' in inconsistent location '/home/kobi/Android/Sdk/build-tools/32.0.0-rc1-2' (Expected '/home/kobi/Android/Sdk/build-tools/32.0.0-rc1')

after I changed the export path in ~/.bashrc, flutter doctor was able to recognize and said all is ok. (though had to accept licenses)

Answer 8

No need to uninstall android studio what you need to do is just go to the andriod studio app go to android sdk and install cmdline toolkit then close the app and type flutter doctor you will get it installed

Answer 9

1. Scroll down and Download Command line tools from https://developer.android.com/studio#downloads
2. Put your Downloaded file (tools) in C:\Users\ABC\AppData\ABC\Android\Sdk
3. Close Android Studio, open Android Studio and check update.
4. Open command line and paste flutter doctor --android-licenses
5. Press y to accept
6. Run flutter doctor and you should be good.

Answer 10

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.

Answer 11

Go to settings:

Go to the Android SDK:

Uncheck the command-line tools:

Check Show details and uncheck the Android command-line tools and then click on Apply then click OK.

Download this package from https://developer.android.com/studio and extract it. Then go to your android sdk location (C:\Users\Pooja\AppData\Local\Android\Sdk) and paste it with the name tools.

Then close and restart Android Studio and check for updates. After installing updates, close Android Studio.

Open the command line and enter:

flutter doctor --android-licenses

And, finally, press y for accept.

All we be solved.

Answer 12

From https://flutter.dev/docs/get-started/install/windows :

Warning: In Android Studio 3.6 or later, you need to manually add the old version of the Android SDK Tools for Flutter to work. To do this:

• Open the Android Studio SDK Manager

• In the Android SDK tab, uncheck Hide Obsolete Packages

• Check Android SDK Tools (Obsolete)

...

This is a known issue that will be addressed in an upcoming version of Flutter.

Answer 13

I encounter the same issue as yours. What I do is to (at least for now...):

1. uninstall Android Studio 3.6 or 3.6.1
2. delete the whole Android SDK directory at C:\Users{your_user_name}\AppData\Local\Android\Sdk
3. install Android Studio 3.5.3. You can find it here(https://developer.android.com/studio/archive) Run the studio again. Do not import the setting of 3.6, and delete them when prompted.
4. go through the Android Studio "Welcome Wizard" again, use standard option.
5. after the installation, you will see that the "tools" folder exists.
6. you will need to install the plugins for dart and flutter again in "Configure"-->"SDK Manager"-->"plugins" within in Android Studio.
