Question

我试图在Windows 10上运行Flutter，但出现一些错误。尝试解决错误“ Android许可证状态未知”。从最近几个小时开始。但是没有运气。我的系统环境如下：

Windows 10，Java版本“ 12.0.2”，2019年7月16日，Android Studio 3.5。

有人可以知道我在这里所缺少的吗？

我尝试了以下命令（ flutter doctor --android-licenses ），并收到如下错误：

C:\Users\me>flutter doctor --android-licenses
A newer version of the Android SDK is required. To update, run:
C:\Users\me\AppData\Local\Android\sdk\tools\bin\sdkmanager --update

Answer 1

您已经接受了许可证吗？如果没有，请尝试

flutter doctor --android-licenses

如How to accept Android licenses

Answer 2

实际上，不需要Android许可证。只需打开android studio并开始一个新的flutter项目即可，玩得开心！如果您想这样做。键入命令：flutter doctor --android-licenses 玩得开心！

Answer 3

我解决了。我设置了JDK_HOME，然后运行以下命令进行修复：

flutter doctor --android-licenses

因此，基本上它无法配置JDK Home，并且发生了该错误。希望，如果您遇到此错误，它将解决问题。

Answer 4

它对我有用。

因此，在此解决方案中，打开您的SDK管理器，然后取消选中Hide Obsolete Packages

现在，您会看到Android SDK Tools (Obsolete) 26.1.1出现。勾选该软件包并点击apply button，然后单击确定按钮。它将下载sdk。然后restart Android Studio

很好，现在，如果您运行flutter doctor，则应获得如下肯定结果

PS D:\Workplace\flutter_projects> flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[√] Flutter (Channel stable, v1.12.13+hotfix.8, on Microsoft Windows [Version 10.0.18363.657], locale en-MY)
