启动新的撰写项目时出现错误java.lang.AbstractMethodError

Question

我在安卓工作室大黄蜂2021.1.1上工作，在创建一个合成项目时遇到了这个错误

java.lang.AbstractMethodError: abstract method "void androidx.lifecycle.DefaultLifecycleObserver.onCreate(androidx.lifecycle.LifecycleOwner)"

该错误发生在我运行该项目时。

我试图将ComponentActivity更改为AppCompatActivity，但出现相同错误

更新

将gradle版本升级到v7.1.1 解决了问题

Answer 1

正如Gabriele Mariotti已经评论的那样，Android Gradle插件7.1.0-alpha04打破了Android Studio中Compose应用程序的启动。您可以通过将应用程序的Min SDK版本设置为24，或者通过命令行将Compose应用程序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，但也必须降级到Android Studio Bumblebee 2021.1.1 Canary 3。
