Android SDK 29 中的混淆器和消费者混淆器问题

Question

我搜索了 Whosebug 和 proguard 的相关问题，但仍然卡住了。

我创建了一个 android .aar 库 (snifferservice)，其中包含与硬件相关的功能和实用程序包。我将此用于连接到此硬件设备的大多数 Android 应用程序。我还有一个应用程序只使用库中的实用程序包。我正在使用 Proguard 来混淆和缩小我的主要应用程序 NoseBook，并使用它来混淆和缩小已完成应用程序中的 aar。由于迁移到 androidx 并更改为目标 API 29，我无法创建发布版本，因为我收到一条错误消息，指出它找不到我专门标记为 [= 的文件的通用超类19=].

我尝试使用 proguard 规则 - 添加和删除 aar 中的其他包，特别是错误中引用的包。什么都不管用。如果我根本不将 Proguard 应用于 aar，一切都可以编译。

我的应用程序使用 Firebase Uuthentication 和 Firebase Cloud Functions。我在 Windows 10 上使用 Android Studio 3.6.3。任何想法将不胜感激。

顶级 Proguard 规则：

我试过向这个文件中添加 support.v4 和 support.v7 命令，还添加和删除 android.content.* 和 weizmann.com.snifferservice.data.* 和 weizmann.com.snifferservice.roomdata.* ，没有帮帮忙。

编辑问题似乎出在房间数据库上。这些是 Proguard 错误：

我已将以下内容添加到我的 proguard 变体中，没有任何帮助。

#this
-dontwarn android.arch.util.paging.CountedDataSource
-dontwarn android.arch.persistence.room.paging.LimitOffsetDataSource

#or this
-keep class androidx.room.**{
    public protected private *;
}
#or this
-keep class * extends androidx.room.RoomDatabase
#or this
-keep class androidx.room.RoomDatabase
#or this and various combinations.
-dontwarn androidx.room.paging.**

Answer 1

最终起作用的是：错误总是出现在第二次优化过程中。我加了

-optimizationpasses 1

一开始的选项，错误从未出现。

我尝试了各种清除缓存选项，updating/reverting 内部 aar 的版本，添加了删除大量 proguard 选项，但没有成功。最坏的情况也给出了 STRING_TOO_LARGE 错误。

感谢 JensV 的帮助！

任何解决此问题的进一步想法仍将不胜感激。
