I am getting error "cmdline-tools component is missing" after installing Flutter and Android Studio... I added the Android SDK. How can I solve them?

Since my Android Studio starting screen looks different from the answers above, I want to share my solution:

• Open Android Studio and click on 'more actions' on the welcome screen.

• Click on 'SDK Manager'

  

• In the 'Preferences' window go to the 'SDK Tools' tab

• Select the 'Android SDK Command-line Tools (latest)' checkbox.

• Click on Apply.

Android SDK Manager screenshot on Windows

Please see the attached screenshot for installing tools from SDK Manager.

1. Open SDK Manager from your Android Studio.

2. You can find SDK manager from the menubar → Tools → SDK Manager or use the icon. As in the picture.

   

3. SDK Tools tab

4. Check Android SDK Command Line Tools as in the picture

5. Apply

   

6. Then again run flutter doctor in your terminal.

My solution process is as follows:

1. ~/Library/Android/sdk/tools/bin/sdkmanager --install "cmdline-tools;latest"

2. Install Android SDK Command-line Tools in Android Studio:

   Preferences → Appearance & Behavior → System Settings → Android SDK → SDK Tools → Android SDK Command-line Tools (latest)

3. flutter doctor

For Windows users

If you still see the same error even after your build tools, tools are installed and added to the user/system path variable, and maybe your sdkmanager location is really not found

• Just type in

flutter config --android-sdk "C:\Users\{Your_User_Name}\AppData\Local\Android\Sdk" # (Default SDK location)

• Add the path inside "" to where your Android SDK folder is located

• Then you can run the licenses to verify any license which is not approved.

This worked for me.

Your Android SDK version requires an update.

Open Android Studio → click Android Studio on the top bar → Preferences → Appearance & behavior (click to open the dropdown) → System Settings (click to open the dropdown) → Android SDK → SDK Tools (tab).

Check Android SDK Command-line Tools (latest) → Apply → click OK. Once the update has finished, run flutter doctor.

Screenshot of the Appearance & Behavior menu

If what flutter doctor said was something like:

[!] Android toolchain - develop for Android devices (Android SDK version 30.0.2)
• Android SDK at /Users/<admin>/Library/Android/sdk
✗ cmdline-tools component is missing
  Run `path/to/sdkmanager --install "cmdline-tools;latest"`

The path/to/sdkmanager for me was:

/Users/<user>/Library/Android/sdk/tools/bin/sdkmanager

So what solved the whole thing for me was running:

/Users/<user>/Library/Android/sdk/tools/bin/sdkmanager --install "cmdline-tools;latest"

For macOS, I ran this command;

cd ~/Library/Android/sdk/tools/bin
./sdkmanager --install "cmdline-tools;latest"

Then when I ran the flutter doctor command again, it confirmed that the problem was solved.

For macOS users:

flutter config --android-sdk "/Users/{YOUR_USER_NAME}/Library/Android/sdk"

Then

flutter doctor --android-licenses

Type "y" for all stops.

Easiest solution:

• Open Android Studio and click settings in the upper left corner of Android studio.
• Search for "SDK tools" in the search box.
• From the SDK tools just check the Android SDK Platform Tools.
• Run flutter doctor to verify. You can also restart Android Studio if you want.
  I hope the problem will be solved.

If you have already downloaded cmdline-tools and the Android SDK, make sure Flutter isn't looking in the wrong directory with:

flutter config --android-sdk=""

I solved this problem on Windows 10 with the following actions:

1. Run the following command in a Windows command prompt or Flutter console:

   flutter config --android-sdk "C:\Users\'your computer name' AppData\Local\Android\Sdk"
   

   (you may need to find and enter your own SDK path)

   The Android SDK location could be found in the Android Studio application* → Appearance & Behavior → System Settings → Android SDK

2. Open your Android Studio, and then → File → Settings → Appearance & Behavior → System Settings → Android SDK → SDK Tools → download Android SDK Command-line Tools (latest) and you are good to go.

If you are a Mac user, just open your terminal and paste:

cd Library/Android/sdk/tools/bin./sdkmanager --install "cmdline-tools;latest"

And hit Enter.

This command will install the latest version of cmdline-tools.

Then, run flutter doctor, and the error will be gone.

For Linux (Ubuntu)

Just copy this command in your terminal and change 'your user name' with your user name without spaces:

/home/your user name/Android/Sdk/tools/bin/sdkmanager --install "cmdline-tools;latest"

I installed the Android SDK platform tool from Android Studio. This helped me to resolve this error.

Error before installation

Installed platform tool from Android Studio

After installation of Platform tools

You have to install Android SDK Command-line Tools. To do that, invoke the menu command File → Settings → Android SDK and download the latest.

You must choose Android SDK on the left side of the Settings window. It’s under Appearance & Behavior → System Settings.

On Windows I did two things to resolve it.

1. Launched Android Studio > More Actions > SDK Manager>SDK Tools and ticked and applied Android SKD Command line tools

2. Entered flutter config --android-sdk C:\Users\xxx\AppData\Local\Android\Sdk into the command line. The path came from the top of the screen in step 1.

For macOS users

If you already have Android Studio installed, simply run:

flutter config --android-sdk "/Users/$USER/Library/Android/sdk" & flutter doctor --android-licenses

Install the Android SDK Command-line Tools:

• For the updated version of Android Studio, the Setting is here:

Settings > Languages & Framework > Android SDK > SDK Tools (TAB)

• For older version:

Settings > Appearance & Behavior > System Settings > Android SDK > SDK Tools (TAB)

If you have installed the latest cmd-line tools from Android Studio, but it still gives the error, then you should do the following.

If you have installed the Android SDK to a custom directory, then you need to copy the path of your SDK folder. Then you have to go to the edit environment variable, click New give a variable name: ANDROID_SDK_ROOT. And a variable value: path of your SDK folder. Click OK.

In the older version of Flutter, this error came with the solution (creating ANDROID_SDK_ROOT), but in the new versions it does not show that.

This is for Windows: If you are still facing the issue even after installing the "Android SDK Command-line Tools(latest)" thru Android Studio -> Settings->Appearance & Behavior -> Systems Settings -> Android SDK -> SDK Tools, You need to configure the flutter for Android SDK Path (Not the environment variable path).

Android SDK Will be installed under Program files e.g. (C:\Program Files (x86)\Android\android-sdk). If not this location, find out the location where it is installed and go to the bin folder (C:\Program Files (x86)\Android\android-sdk\cmdline-tools\7.0\bin) and run

flutter config --android-sdk "C:\Program Files (x86)\Android\android-sdk"

After this run flutter doctor, now this issue should be resolved.

For me, running this command worked perfectly:

flutter config --android-sdk /path/to/your/sdk

Goto:

1. Tool->SDK Manager and Apply SDK command line toolkit.

I executed the below command to fix the issue on Mac:

/Users/<user username>/Library/Android/sdk/tools/bin/sdkmanager --install "cmdline-tools;latest"

For anyone on Linux, I've wrote a script to download and setup the android SDK and flutter. I was getting errors with flutter doctor being unable to find the sdkmanager and cmdline-tools and this fixed it.

Let's see how long until they make a change to break this script lol.

See the github repo for possible updates to this :).
