在制作React Antive应用程序时，我会收到以下错误。.我在下面附加了错误和gradle文件。我还尝试使用EnableJetifier迁移到Androidx，并且Useandroidx既真实又干净，但仍然没有运气。
- 出了什么问题：执行失败的任务'：react-native-background-job：compiledebugjavawithjavac'
错误：

需要在AndroidX。
中迁移确实在您的库中更改
ex：android.support.annotation.nonnull更改为androidx.annotation.nonnull
https://developer.android.com/jetpack/androidx/migrate
或尝试此https://github.com/facebook/react-native/issues/21722
Androidx，Android.Support已淘汰，使用Androidx，而在给定的节点模块路径中导入Androidx。希望这将起作用
