java - 无法运行 flutter doctor --android-licenses

Question

我想在我的电脑上使用 flutter，我使用 Android Studio 和 Visual Studio Code。当我运行 flutter doctor 时，出现了这样的警告，

[√] Flutter (Channel stable, v1.17.3, on Microsoft Windows [Version 10.0.14393], locale id-ID)
[!] Android toolchain - develop for Android devices (Android SDK version 29.0.3)
    X Android license status unknown.
      Try re-installing or updating your Android SDK Manager.
      See https://developer.android.com/studio/#downloads or visit visit
      https://flutter.dev/docs/get-started/install/windows#android-setup for detailed instructions.
[√] Android Studio (version 4.0)
[√] VS Code (version 1.45.1)
[!] Connected device
    ! No devices available

! Doctor found issues in 2 categories.

但是当我运行 flutter doctor --android-licenses 时出现这样的错误，错误与我运行命令 sdkmanager 相同/p>

C:\Users\Halim>flutter doctor --android-licenses

        ... 5 more

在这种情况下我使用 jdk-13.0.1 并将其添加到路径环境中，目前我使用的是 Windows 10

对于环境变量我使用的设置如下

ANDROID_HOME = C:\Users\Halim\AppData\Local\Android\Sdk
ANDROID_SDK_ROOT = %ANDROID_HOME%\tools
JAVA_HOME = C:\Program Files\Java\jdk-13.0.1

这是我的 Windows 10 上的路径

%USERPROFILE%\AppData\Local\Microsoft\WindowsApps
C:\Users\Halim\AppData\Local\Programs\Microsoft VS Code\bin
C:\Users\Halim\AppData\Roaming\npm
%ANDROID_HOME%\platform-tools
%ANDROID_SDK_ROOT%\bin
%ANDROID_HOME%\tools
C:\Program Files\nodejs
%JAVA_HOME%\bin
C:\xampp\php
C:\flutter\bin

尝试使用 java 1.8 而不是 13.0.1，这可能会解决您的问题。

此错误与此错误类似:

Flutter A newer version of the Android SDK is required. To update, run: error?
