quickstart-unity: Firebase Auth crash in Initialization step when running the app for the second time

Please fill in the following fields:

Unity editor version: 2019.1.8 Firebase Unity SDK version: 6.1.1 (I tried also 6.2.1) Firebase plugins in use (Auth, Database, etc.): Auth Additional SDKs you are using (Facebook, AdMob, etc.): nothing Platform you are using the Unity editor on (Mac, Windows, or Linux): Windows Platform you are targeting (iOS, Android, and/or desktop): Android

Please describe the issue here:

  • Download Auth test app from “Firebase-Test”.
  • Add Firebase SDK to the project
  • Build and run
  • Sign in anonymously
  • Close the app (by pressing android hardware back Button)
  • Open the app again and the crash will appear at startup

Please answer the following, if applicable:

The problem appear in my app. Then I tried to build a small app which only contain the firebase functionality from my original app and got the same crash. Lastly I tried with the test app from “Firebase-Test” apps and got the same.

Try this if the scripting backend “IL2CPP”

Firebase.FirebaseApp.DefaultInstance.Dispose();
Application.Quit();

Hi all, we’re looking into this and I’ll let you know when we have a fix.

There is one workaround we have found which a) might help others workaround this b) might help you investigate where the problem is. The only downside is that your app won’t have backup allowed.

Also if you install the app without this workaround, delete all it’s data and cache and run it, it will work, but that’s not a solution, just one more hint to help with pinpoint the issue.

Ok so how to workaround it:

  • We had to update to Unity 2019.1.12 (it didn’t work on 2019.1.10)
  • Add this to you Manifest like in example bellow android:allowBackup=“false” tools:replace=“android:allowBackup”

<application android:icon="@drawable/app_icon" android:label="@string/app_name" android:allowBackup="false" tools:replace="android:allowBackup" ...>

That should make it work

Awesome, thanks!

We are aware of this issue and tracking it, and will update this thread when it’s fixed. If the steps above do not help, definitely let us know (similar for @eduardocoelho).

I can confirm that the suggestion from @nextvern and @chkuang-g to Dispose() the FirebaseApp before OnApplicationQuit() does resolve the issue! This was confirmed with Unity 2018.4.2f1 and 2019.2.1f1 and Firebase 6.1.1.

We think this is fixed in 6.5.0 https://firebase.google.com/support/release-notes/unity#version_650_-_september_10_2019

@chkuang-g Yes, I’m getting the same stack trace each time. and as @amoswazana mentioned, I still have the same crash even after update to 2019.1.11f1.|

The problem isn’t solved.
