react本机清单合并失败

Question

添加react-native-admob库后，我收到下一条错误消息

清单合并失败：[com.android.support:support-compat:28.0.0]AndroidManifest.xml:22:18-91中的属性application@AppComponentFactory value=(Android.support.v4.app.CoreComponentFactory）也出现在[AndroidX.Core:Core:1.0.0]AndroidManifest.xml:22:18-86 value=(AndroidX.Core.App.CoreComponentFactory中。建议：将'tools:replace=“android:AppComponentFactory”‘添加到AndroidManifest.xml:7:5-117的元素中以覆盖。

我尝试按照建议添加'tools:replace=“android:AppComponentFactory”，但构建仍然失败。

我不确定我从哪里依赖AndroidX.core:core:1.0.0。请告诉我如何解决清单合并冲突。谢谢

lib引用了旧的Android支持库中的一些文件和类。从0.60开始，使用AndroidX支持库，而不是Android-support。这意味着所有的依赖都必须依赖它。

幸运的是，有一个工具可以将lib转换为新的格式。它被称为jetifier：https://www.npmjs.com/package/jetifier。您可以使用它并将其添加为yarn/npm post install脚本，以便在每个yarn/npm安装后将其应用于所有node_modules依赖项。

您的库还有另一种选择，因为另一位作者报告说，他创建了react-native-admob的分叉，并将其更新到最新的AndroidX支持库，请参阅https://github.com/sbugert/react-native-admob/issues/459
