capacitor - 空对象引用上的“void com.getcapacitor.Bridge.onStart()”

Question

我将 React 应用程序包装到 Capacitor 中。当我从 AndroidStudio 运行它时，应用程序会立即启动和停止。我收到以下内容。

E/AndroidRuntime: FATAL EXCEPTION: main
    Process: com.example.app, PID: 20226
    java.lang.NullPointerException: Attempt to invoke virtual method 'void com.getcapacitor.Bridge.onStart()' on a null object reference

似乎缺了什么。我检查了教程。@capacitor/core 存在。
