这个问题困扰了我一天

当我试着跟着内容提示进行授权认证时

✗ 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

当我输入了这 'flutter doctor --android-licenses' 时遇到报错

yangjie@yangdeMBP ~ % flutter doctor --android-licenses

Error: A JNI error has occurred, please check your installation and try again

解决:检查你在计算机上安装的 java 版本。如果是版本 8，则安装 Android SDK 命令行工具 8.0 并卸载最新版本。
