Android toolchain - I develop for Android devices (Android SDK version 30.0.3):
X cmdline-tools component is missing
Run `path/to/sdkmanager --install "cmdline-tools;latest"`
See https://developer.android.com/studio/command-line for more details.
The solution for me was opening Android Studio and going to SDK Manager, switch to the SDK Tools tab and check Android SDK Command-line Tools (latest).
Don't forget to add to your PATH the tools and platform-tools folder that are inside your SDK.
Android SDK Manager screenshot on Windows
Please see the attached screenshot for installing tools from SDK Manager.
Since my Android Studio starting screen looks different from the answers above I want to share my solution:
My solution process is as follows:
~/Library/Android/sdk/tools/bin/sdkmanager --install "cmdline-tools;latest"

flutter doctor.
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
Try this
Just type in
flutter config --android-sdk "C:\Users\barma\AppData\Local\Android\Sdk" # (since my SDK folder is here)
Add the path inside "" to where your Android SDK folder is located
Then you can run the licenses to verify any license which are not approved.
This worked for me.
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"
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.
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.
Easiest solution:
flutter doctor to verify. You can also restart Android Studio if you want. I solved this problem on Windows 10 with the following actions:
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
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 have already downloaded cmdline-tools and the Android SDK, make sure Flutter isn't looking in the wrong directory with:
flutter config --android-sdk=""
For macOS users:
flutter config --android-sdk "/Users/{YOUR_USER_NAME}/Library/Android/sdk"
Then
flutter doctor --android-licenses
Type "y" for all stops.
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 resolved this error.
You have to install Android SDK Command-line Tools. To do that, invoke menu command File → Settings → Android SDK and download the latest.
You must choose Android SDK in the left side of the Settings window. It’s under Appearance & Behavior → System Settings.
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.
For MacOS Users
If already have android studio installed simply run:
flutter config --android-sdk "/Users/$USER/Library/Android/sdk" & flutter doctor --android-licenses
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.
