运行项目时出现错误。

我尝试将 ComponentActivity 更改为 AppCompatActivity 但同样的错误发生

更新

升级gradle版本到v7.1.1解决的问题

Answer 1

就像 Gabriele Mariotti 已经评论过的那样，Android Gradle 插件 7.1.0-alpha04 打破了 Android Studio 中 Compose 应用程序的启动。您可以通过将您的应用最小 SDK 版本设置为 24 或通过命令行将 Compose 应用安装到您的设备并在那里启动来解决此问题。

或者您可以将 AGP 降级到 7.1.0-alpha03，但随后您也必须降级到 Android Studio Bumblebee 2021.1.1 Canary 3。
