调研方向

从堆栈跟踪中的 FirebaseAuth 初始化以及 ProfileRepositoryImpl.kt 中报告的 private val firestore = FirebaseFirestore.getInstance() 开始。使用较早 SDK 版本中持久化的身份验证状态，而不是全新安装，比较 Firebase BoM 34.5.0 和 34.12.0 之间的行为。如果 repository 支持，则通过回归测试或已确认的复现来识别并处理 unknown-enum 启动崩溃，即视为完成。

描述

api: auth api: firestore
[REQUIRED] Step 2: Describe your environment
  • Android Studio version: Android Studio Quail 1 | 2026.1.1
  • Firebase Component: Authentication
  • Component version: 24.0.1
[REQUIRED] Step 3: Describe the problem
Steps to reproduce:

On app startup, the application eagerly initializes Firestore (which forces FirebaseAuth initialization). For only one 1-2 users (for about 50 000 users) — appears to be those with pre-existing persisted auth state written by a previous SDK version — FirebaseAuth.
throws while (de)serializing an internal protobuf enum, crashing the whole app at Application.onCreate.

It is not reproducible on a fresh install / signed-out state; it only reproduces for this user with existing persisted auth state, which is why we cannot trigger it on demand. It is a hard, non-recoverable startup crash for affected users.

The failure is:

java.lang.IllegalArgumentException: Can't get the number of an unknown enum value.

     ... (Hilt-injected @Singleton created during Application.onCreate)
 Caused by: java.lang.IllegalArgumentException: Can't get the number of an unknown enum value.
Relevant Code:

Crash is reached simply by initializing Firestore, which forces FirebaseAuth init.

private val firestore = FirebaseFirestore.getInstance()

It seems to be introduced since we have updated firebase-bom from 34.5.0 to 34.12.0

Thanks a lot.
