Android 带前卫的火基

我正在用firebase制作一个应用程序，它工作得非常好。 直到我打开ProGuard甚至R8

我基本上尝试了在互联网上找到的所有ProGuard规则组合，我甚至尝试过

-keep class com.firebase.** {*;}
-keep class mypackage.** {*;}

我有一个完全相同的项目，只是使用了不同的代码结构，并且它确实可以完美地使用以下规则：

-keepattributes *Annotation*
-keepattributes SourceFile,LineNumberTable
-keep public class * extends java.lang.Exception

-keepattributes Signature
-keepclassmembers class com.tritrio.anabi2y.model.** {*;}

-keep public class * implements com.bumptech.glide.module.GlideModule
-keep public class * extends com.bumptech.glide.module.AppGlideModule
-keep public enum com.bumptech.glide.load.ImageHeaderParser$** {
  **[] $VALUES;
  public *;
}

-dontwarn com.firebase.ui.auth.**

以下是StackTrace：

R8是罪魁祸首

禁用后，一切正常

我已将此问题报告给和firebase。

您应该在正式报告中使用规则

这些通常是firebase android库的规则

-keepattributes EnclosingMethod
-keepattributes InnerClasses

-dontwarn org.xmlpull.v1.**
-dontnote org.xmlpull.v1.**
-keep class org.xmlpull.** { *; }
-keepclassmembers class org.xmlpull.** { *; }

我已经发布了解决方案。我试过了，没用，谢谢你的回答。救命！我花了好几个小时在这上面
