FirebaseAuthFallbackService memory leak

[READ] Step 1: Are you in the right place?

yes

[REQUIRED] Step 2: Describe your environment

• Android Studio version: 4.1.2 Stable
• Firebase Component: Firebase Authentication
• Component version: 20.0.2

[REQUIRED] Step 3: Describe the problem

LeakCanary is telling me that "FirebaseAuthFallbackService " is leaking. I just “AuthStateListener” in my ActivityClass which lives through the entire app lifecycle, to check if the user signed out. And “Firebase.auth” for taking currentUser instance. That’s all

Steps to reproduce:

Happening every time I open the app, sometimes when I close the app, sometimes when It goes to the background, LeakCanary starts dumping the heap and throwing this memory leak.

Relevant Code:

┬───
│ GC Root: Global variable in native code
│
├─ com.google.firebase.auth.api.fallback.service.zza instance
│    Leaking: UNKNOWN
│    Retaining 1.7 kB in 10 objects
│    zza instance of com.google.firebase.auth.api.fallback.service.
│    FirebaseAuthFallbackService
│    ↓ zza.zza
│          ~~~
╰→ com.google.firebase.auth.api.fallback.service.FirebaseAuthFallbackService
​  instance
​     Leaking: YES (ObjectWatcher was watching this because com.google.firebase.
​     auth.api.fallback.service.FirebaseAuthFallbackService received
​     Service#onDestroy() callback)
​     Retaining 1.2 kB in 9 objects
​     key = d411935b-9bcd-4a8d-8362-a6c8687aec0e
​     watchDurationMillis = 5285
​     retainedDurationMillis = 281
​     mApplication instance of com.upgrades.venue.pro.MainApplication
​     mBase instance of android.app.ContextImpl
