如何解决：Android许可状态未知，同时找不到Android sdkmanager工具？

Question

我试过了所有我找到的东西（GitHub问题，SO问题）。还尝试从Android Studio重新安装Android SDK（29）。

我没有安装**Android SDK Command-line Tools (latest)**。 - Gabriel Patricio Bonilla

Answer 2

下载 https://developer.android.com/studio#command-tools 并提取到

C:\Users\Zheny\AppData\Local\Android\Sdk 文件夹中

并将路径设置为如下：

C:\Users\Zheny\AppData\Local\Android\Sdk\tools\bin

重新启动 PowerShell 或命令提示符，并执行以下命令：

flutter doctor --android-licenses

Answer 3

请按照以下步骤操作：

1. 打开SDK管理器
2. 进入SDK工具
3. 从SDK管理器中删除“Android SDK工具”

4. 首先取消选中“隐藏过时的软件包”，然后选择“Android SDK工具（过时）”，进行安装。

5. 运行flutter doctor --android-licenses，并选择提示中的y。

运行flutter doctor，一切都会好起来的！！！

Answer 4

根据您的安装路径，您的系统变量应该为： ANDROID_HOME C:\Users\\AppData\Local\Android\sdk JAVA_HOME C:\Program Files\Android\Android Studio\jre\

您的路径应该为： C:\Program Files\Android\Android Studio\jre\bin C:\src\flutter\bin

然后在命令提示符中运行 "flutter doctor"（不带引号）。

如果出现相同的错误，请打开 Android Studio，转到“设置”，导航到“外观和行为>系统设置>Android SDK”，然后在窗口顶部和 Android SDK 位置右侧单击“编辑”，从打开的窗口中更新当前的 SDK 管理器并安装最新的 API（如果尚未安装）。一旦在此窗口中更新或安装了所有内容，请关闭 Android Studio 并关闭命令提示符。

打开一个新的命令提示符，再次运行 "flutter doctor"（不带引号）。按照软件说明接受所有 Android 许可证。
