Question

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。每当我尝试启动它时，它就会崩溃。错误消息似乎表明它正在尝试在我的应用程序的命名空间中引用androidx：

我不确定从哪里开始寻找解决此问题的方法。

Answer 1

我解决了这个问题。我向AndroidManifest.xml添加了不需要的内容。我从其他地方复制并粘贴了此文件，但事实证明我不需要此文件并引起了问题：

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

删除这些行解决了我的问题。

java.lang.ClassNotFoundException：找不到类“ com.my_app_name.androidx”
