启用 Proguard 后无法实例化片段

【中文标题】启用 Proguard 后无法实例化片段【英文标题】：Unable Instantiate Fragment after Enabling Proguard 【发布时间】：2021-05-04 04:27:37 【问题描述】：启用 minified 和 proguard 后，我遇到了运行时异常。它只发生在我使用深度链接导航到的动态功能模块内部的片段上。 :app 模块中的另一个片段不会受到深度链接或使用默认底部视图导航的影响。这是logcat：

我尝试添加从here 获得的这一行，但不起作用。
-keepnames class androidx.navigation.fragment.NavHostFragment
有人经历过吗？我该怎么办？
更新：
shared_depencies.gradle 跨模块实现：

共享依赖被应用：

核心模块依赖：

应用程序模块依赖项
dependencies

动态特性模块依赖：
dependencies
implementation project(":app")
implementation project(":core")
//noinspection DifferentStdlibGradleVersion
implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
附加信息：
如果:app 模块也被混淆，就会发生这种情况
如果只对:core 模块进行混淆处理就可以了
动态功能模块根本没有被混淆
【问题讨论】：
您的问题与 ProGuard 未保留的片段无关，问题是“调用片段构造函数导致异常”并且 看起来与您的方式有关设置您的 Kotlin 依赖项。请包含您的依赖项块。 添加了依赖块 【参考方案1】：事实证明，我必须更改在动态功能模块片段中传递给 Dagger 的上下文。因此，在我的情况下，请使用 requireActivity().appicationContext，而不是使用 requireContext()。代码应该是这样的：
DaggerFavoriteComponent.builder()
.context(requireActivity())
.appDependencies(
EntryPointAccessors.fromApplication(
requireActivity().applicationContext,
FavoriteModuleDependencies::class.java
)
)
.build()
.inject(this)
【讨论】：
以上是关于启用 Proguard 后无法实例化片段的主要内容，如果未能解决你的问题，请参考以下文章
调用片段活动错误无法实例化活动。无法转换为 android.app.Activity
