带有 Java 8 的 Flutter/Android SDK

设置我的 Mac 以进行本地 Flutter 开发。我按照指南中提到的所有步骤进行了操作，安装了 Android Studio 并更新了 SDK。以下是我flutter doctor -v所说的：

所以我用 Google 搜索并找到了这些链接：

我尝试了所有方法，但没有一个能解决这个问题，当我尝试时，flutter doctor --android-licenses我得到了这个错误：

A newer version of the Android SDK is required. To update, run:
/Users/yeshwanths/Library/Android/sdk/tools/bin/sdkmanager --update

但是我今天才从 Android 网站下载了 Android Studio 和 SDK。这非常令人困惑。有人能就此提出建议吗？

答案1

我也遇到了同样的问题。我尝试了所有可能的方法，但都没有用。剩下的唯一解决方案就是降级 Java 版本。

答案2

您可以尝试指定配置到您的 android studio 的android-studio-dir路径flutter config --android-studio-dir /path/to/android-studio，然后运行flutter doctor --android-licenses，您应该能够接受许可证。
