What i tried.

Crashlytics.IsCrashlyticsCollectionEnabled = false;
Crashlytics.SetUserId("test user");
Crashlytics.SetCustomKey("test key", "test value");

It turns out to crash by calling the above.
However, even if the above code is deleted after a crash,
this time it crashes with the following code.

FirebaseApp app = Firebase.FirebaseApp.DefaultInstance;

Please answer the following, if applicable:

What's the issue repro rate? (eg 100%, 1/5 etc)

100%

[sunagimoApp]

Firebase Unity SDK ver 6.6.0 : Crashed!
Firebase Unity SDK ver 6.5.0 : Crashed!
Firebase Unity SDK ver 6.4.0 : Crashed!
Firebase Unity SDK ver 6.0.0 : Crashed!
Firebase Unity SDK ver 5.7.0 : Crashed!
Firebase Unity SDK ver 5.5.0 : Not Crashed!

I tried to raised the Unity version(Unity2019.2.11f1）, but it also crashed.

Do you have any plans to fix it?
Is there a way to avoid it?
We Need to support Android 4.4.2.

[stewartmiles]

@sunagimoApp this is likely related to a bug in Unity which doesn't close the entire process when the app exits which leaves any native components in the application (in this case the C/C++ part of Firebase) in a partially initialized state. @chkuang-g posted a workaround in #416 (comment) and is working on a solution.

[sunagimoApp]

@stewartmiles
Thank you for the reply.
I'll confirm #416 comments.

[sunagimoApp]

Hi @stewartmiles
I tried the following with reference to #416 (comment), but it also crashed.
・Change Unity Version(2019.2 or this issues version）
・Call 'Firebase.FirebaseApp.DefaultInstance.Dispose()' before the application exits.
・Change Firebase Unity SDK Version(6.1.1 or this issues version）

Also, not only IL2CPP but also Mono crashed.

[stewartmiles]

@sunagimoApp is this reproducible in our Crashlytics quickstart (i.e the application in this repo)? I haven't been able to reproduce this behavior so I wonder whether something else in your application is stomping memory or changing the initialization flow which is resulting in this.

[sunagimoApp]

@stewartmiles
Not reproduced in Crashlytics quickstart.
It is reproduced by calling the following process during initialization.

Crashlytics.IsCrashlyticsCollectionEnabled = true;
Crashlytics.SetUserId("test user");
Crashlytics.SetCustomKey("test key", "test value");

[stewartmiles]

@sunagimoApp in the Crashlytics quickstart's InitializeFirebase() method (called after all Firebase's SDK has been initialized) I added the lines you suggested:

Crashlytics.IsCrashlyticsCollectionEnabled = true;
Crashlytics.SetUserId("test user");
Crashlytics.SetCustomKey("test key", "test value");

I've attached the output of adb logcat on a Nexus 5 running Android 4.4.

The app starts / quits with no issues most of the time.

On occasion Unity crashes the application when closing the application, Firebase's SDK isn't in the callstack.

In terms of next steps, I think it would be useful to share your modified Crashlytics quickstart project with us along with the apk that is problematic so that we can reproduce and debug on our side.
