[Bug] Offline Support For Realtime DB does not work with Unity Android SDK

[saifullah73]

Description

ISSUE

I am trying to enable offline capabilities for Realtime DB on Android, but it does not seem to work. The offline capability works fine on Editor and even though Android seems to have the feature, it doesn't work on it.

Code Used

FirebaseApp firebaseApp = Firebase.FirebaseApp.Create(options, Guid.NewGuid().ToString());			
_realtimeDbInstance = FirebaseDatabase.GetInstance(firebaseApp);
_realtimeDbInstance.SetPersistenceEnabled(true);

Reproducing the issue

On Editor:

Launch the game, turn off internet, change player configs, close the game, relaunch after enabling internet. The updated configs show up

On Android:

Repeat the same steps, but after relaunch, the old configs show up , since they were never written to the firebase realtime db

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Thanks for reporting, @saifullah73. I was able to reproduce the behavior. It looks like the Unity Editor, and the native Firebase Android Quickstart works properly. I'll go ahead and inform our engineers. Thanks!
