java.lang.ClassNotFoundException: 未找到 class "com.my_app_name.androidx"

Question

在尝试将我的 Android 应用程序从旧版本的 React Native (0.55.4) 升级到最新版本 (0.60.4) 之后。现在我无法启动我的应用程序。每次我尝试启动它时它都会崩溃。错误消息似乎表明它正在尝试在我的应用的命名空间中引用 androidx:

我不确定从哪里着手解决这个问题。

Answer 1

我解决了这个问题。我在我的 AndroidManifest.xml 中添加了一些我不需要的东西。我从其他地方复制并粘贴了它，但事实证明我不需要它并导致了问题：

<application
    ...
    tools:replace="android:appComponentFactory"
    android:appComponentFactory="androidx"
>

删除这些行解决了我的问题。
