Mac配置Flutter安卓环境问题记录

问题

安装完Android Studio后运行

1	flutter doctor

检查，出现下面的错误：

[!] Android toolchain - develop for Android devices (Android SDK version 33.0.0)
    ✗ cmdline-tools component is missing
      Run `path/to/sdkmanager --install "cmdline-tools;latest"`
      See https://developer.android.com/studio/command-line for more details.
    ✗ Android license status unknown.
      Run `flutter doctor --android-licenses` to accept the SDK licenses.
      See https://flutter.dev/docs/get-started/install/macos#android-setup for
      more details.
    ...

解决

第一个是cmdline-tools SDK没有安装，设置Android Studio的SDK Manager,按照下图勾选安装 SDK Tools
按照提示运行命令,并选择同意即可
1
flutter doctor --android-licenses
网址无法访问，换成可访问的地址即可
- 找到flutter sdk的文件目录，打开下面路径文件
  
  flutter\packages\flutter_tools\lib\src\http_host_validator.dart
- 修改出错的网址址
  
  将其中的 https://maven.google.com/ 修改为 https://dl.google.com/dl/android/maven2/
  再将 kPubDevHttpHost 和 kgCloudHttpHost 两个常量分别修改为 https://pub.flutter-io.cn/ 和 https://storage.flutter-io.cn/
如下图所示：

再运行 flutter doctor 查看已经解决。
