Java 类型“javax.inject.Inject”由多个托管类型生成。请更改 [注册] 属性

Question

已将 Xamarin.Android 项目迁移到 AndroidX，并且必须更新一些包。现在我无法构建我的项目并收到以下错误消息：

请告知如何修复它或如何更改 [Register] 属性以及需要在哪里完成。我无法删除这些包，其他包依赖于它们。

在 migration 之后，我们需要针对该工具未涵盖的场景进行一些手动命名空间更改。

AndroidX 替换了 Android support libraries ，因此对 Android 支持库类型的任何引用都必须替换为对 AndroidX 类型的引用。

以下table显示命名空间的变化

Android support library namespace	AndroidX namespace
Android.Support.V4.App	AndroidX.Core.App
Android.Support.V4.Content	AndroidX.Core.Content
Android.Support.V4.App	AndroidX.Fragment.App
Android.Support.V7.App	AndroidX.AppCompat.App
Android.Support.V7.Widget	AndroidX.AppCompat.Widget

更新

删除所有包并重新添加到项目中。
