TLDR
java.lang.RuntimeException：无法实例化AndroidPlatform类。
minifyEnabled和shrinkResources的App Bundle的 release 版本应与 debug 版本相同。按照Android documentation，在应用程序的 build.gradle 文件中仅适用于 release 版本。
应用程序的 release 版本立即崩溃。这是Firebase库构建App Bundle方式的一个新问题。
在没有minifyEnabled和shrinkResources的情况下，应用程序可以按预期的生产方式运行，并且应用程序大小从〜4mb到〜10mb。
错误日志表明这是Firebase兼容性问题-What ProGuard configuration do I need for Firebase on Android?
ProGuard存在类似的问题-transformClassesAndResourcesWithProguardForRelease FAILED。

1-Adding proguard.cfg rules for Firebase。
-keep class com.firebase.** { *; }
-keep class org.apache.** { *; }
-keepnames class com.fasterxml.jackson.** { *; }
-keepnames class javax.servlet.** { *; }
-keepnames class org.ietf.jgss.** { *; }
-dontwarn org.w3c.dom.**
-dontwarn org.joda.time.**
-dontwarn org.shaded.apache.**
-dontwarn org.ietf.jgss.**
# Only necessary if you downloaded the SDK jar directly instead of from maven.
-keep class com.shaded.fasterxml.jackson.** { *; }
2-{{3}}用于应用程序的类。
# Add this global rule
-keepattributes Signature
# This rule will properly ProGuard all the model classes in
# the package com.yourcompany.models. Modify to fit the structure
# of your app.
-keepclassmembers class com.yourcompany.models.** {
*;
}

我遇到了类似的问题，并且从Fabric完全迁移到Firebase Crashlytics为我解决了该问题：https://firebase.google.com/docs/crashlytics/get-started-new-sdk?platform=android&authuser=0
希望这会有所帮助！
