Question

我试图在我的 VS Code 上安装 Flutter，但我一直遇到这个问题。 Android 许可证状态未知。

我回到 Android Studio 并更新了所有 SDK 许可证。没有帮助。我该如何解决？

Answer 1

通过转到 Android Studio> 设置 > 外观和行为 > 系统设置 > Android SDK > SDK 工具并选中下载 Android SDK 命令行工具（最新）选项来解决此问题。

Android SDK Command Line Tools

然后重新启动 VS Code 并重新运行 flutter doctor --android-licenses 并输入 y 以接受所有许可。现在应该像魅力一样工作！
