resolve this.

Answer 1

It looks like you might be missing the command-line tools.

If you want to install the command-line tools without installing Android studio then I would suggest taking a look at this website here . It lists all the android sdk tools you can download without needing to install android studio.

If you do want to install android studio I was able to solve this problem just recently by going to Tools>SDK Manager>SDK Tools and selecting "Android SDK Command-line Tools (latest)", then hit okay to install the tools.

After you do that try doing flutter doctor --android-licenses again

Answer 2

* N\B: I believe by default you had already installed thhe commandline tools. Go to the folder containing the sdkmanager.bat file and then open the cmd from there. The cmd should show the folder in which it is open. Run the following command, 'sdkmanager.bat --install "cmdline-tools;latest" After completely running the task close the cmd and open a new one and run 'flutter doctor'

Answer 3

此错误可以从 android studio 解决，转到 SDK 工具，然后单击 android SDK 命令行工具并安装它们。

Answer 4

I ran into two issues. I started with a default install of Android Studio and flutter from flatpack.

1. When you download commandlinetools...zip from Google, and unzip it, you get directories like cmdline-tools/bin , cmdline-tools/lib etc. That doesn't work. You need to create a latest subdirectory and move everything in there. eg /home/user/Android/Sdk/cmdline-tools/latest/bin/
2. Now you can run the updater. Something that works will look like ~/Android/Sdk/cmdline-tools/latest/bin/sdkmanager --sdk_root=/home/user/Android/Sdk --install "cmdline-tools;latest" . When I first installed, instead of /home/user/ I did ~/ and that caused problems subsequent to updating. The value you provide to --sdk_root gets cached somewhere.

Now you can run flutter doctor successfully to accept the licenses.

On Windows, you may also need to set the android-sdk location. It's usually in C:\$USER\AppData\Local\Android\Sdk .

You can set it by running flutter config --android-sdk <path to android sdk> .

This fixed the same issue for me.
