I don't why google developers release this bugs?
I lost many many users from upgrade this release

paulinon · 2021-11-02T17:48:37Z

Hi @Jack37,

After building an app based on the information you provided, I haven't been able to replicate the issue so far as my app didn't crash.

Could you provide a minimal, reproducible example so that we can analyze what's causing this? Could you also confirm if there are additional steps necessary to be able to generate logs similar to what you provided?

Aha! I found a clue. It turns out the issue comes with calling MobileAds.Initialize() from the AdMob Unity SDK around the same time as FirebaseApp.CheckAndFixDependenciesAsync(). Removing either one of those calls reliably fixes the crash for me. This is still in my main project, let me see about a minimal test project to prove my hunch now...

aroman · 2021-11-04T09:38:17Z

Okay, I can confirm that I can repro in a blank Unity project. Here are the steps for minimal repro @paulinon:

Create a new blank project in Unity (I chose 2D template). I used Unity 2021.2, but other versions may be affected.
Import GoogleMobileAds-v6.1.2.unitypackage (latest stable at time of writing)
Import latest stable FirebaseAnalytics.unitypackage. Presumably any Firebase package would work; we just need the core library after all.
Create this script (below) and add it to the scene
Supply an AdMob app ID in the admob config ScriptableObject. Any string should work.
Switch build target to Android and build & run to device
It should crash

using Firebase;
using Firebase.Extensions;
using GoogleMobileAds.Api;
using GoogleMobileAds.Common;
using UnityEngine;

public class ReproductionTest : MonoBehaviour
{
    private void Start()
    {
        MobileAds.Initialize(_ => MobileAdsEventExecutor.ExecuteInUpdate(() => Debug.Log("admob done")));
        FirebaseApp.CheckAndFixDependenciesAsync().ContinueWithOnMainThread(_ => Debug.Log("firebase done"));
    }
}

I haven't attempted a workaround (I should sleep) but I wonder if forcing these libraries to initialize in serial (one to wait for the other before loading) would work.

Jack37 · 2021-11-04T10:00:35Z

Great find! So far I can confirm that I am using AdMob, which I removed from latest release, to see if crashes will go away. However I am using AdMob mediation adapter for IronSource instead of plain AdMob SDK.

aroman · 2021-11-04T18:04:19Z

Ahhh, my minimal repro attempt is flawed — I was getting a crash for a different reason, which is that if your AdMob App ID is invalid, your app will hard crash (terrible behavior in its own right). So, while this doesn't explain why removing MobileAds.Initialize in my actual project fixes the crash, it does mean that my explanation might not be correct.

paulinon · 2021-11-04T18:10:39Z

Thanks for the additional information, @aroman and @Jack37. Given that you make use of AdMob, could you confirm if removing this from your implementation makes a difference? If it doesn't, a minimal, reproducible example of your project would come in handy so that we can analyze this behavior.

aroman · 2021-11-05T04:08:22Z

@paulinon as you requested, I have created a repo of a minimal reproducible example demonstrating this issue:

https://github.com/aroman/TestFirebaseCrash

Removing AdMob does seem to make a difference; there seems to be an interaction between multiple Google libraries going on here. My minimal reproducible repo contains only Google plugins — AdMob for Unity and Firebase for Unity.

Jack37 · 2021-11-05T12:43:03Z

Removing AdMob adapter did not help for me. But I still have other Google libraries that may cause this.

Hi folks,

If you see firebase::messaging::CompleteStringCallback in the callstack, this very likely fits this profile #1160 (comment)

Please upgrade to the latest Firebase and see if that resolves your issue.

@Jack37
I cannot tell if this is your case from your callstack. Could you:

Try to upgrade Firebase SDK and see if that fixes your issue.
Confirm if this happens on Android, iOS or Unity editor.

Thank you

aroman · 2021-11-11T05:42:02Z

I have updated all firebase pacakges in my project 8.6.1 and I can confirm that I'm still seeing this crash. It doesn't happen 100% of the time, but >50% of the time on my test device (Samsung A10). The errors I'm seeing are coming from the device itself via ADB, and unfortunately the stack trace stops about where @kolobokspb's does.

I'm getting same error with @aroman

TBarendt · 2021-11-12T13:50:53Z

firebase/firebase-cpp-sdk#745 there was one more edge case for this during shutdown

devup1225 · 2021-11-13T05:57:00Z

Make sure the Firebase and Unity Ads initialization order is guaranteed.
After I guaranteed the initialization order, the problem was solved.

Conflicts were resolved by ensuring Firebase initialization and Unity Ads initialization order.

@chkuang-g This is probably my case too, as there seem to be two callstacks. This one is same as mine, on a 8.6.1 version #1169 (comment). This happens on Android.

a-maurice · 2021-11-19T22:24:42Z

We haven't been able to completely reproduce the problem on our end, but we just released 8.6.2, which contains a potential fix for the issue.

naklow12 · 2021-11-22T07:37:59Z

We haven't been able to completely reproduce the problem on our end, but we just released 8.6.2, which contains a potential fix for the issue.

In my case, I was using Firebase 8.1 and I updated to 8.6.1 for adding message service. Then this problem occured and I'm using Admob, Facebook, Adjust, UnityAds, Applovin etc SDKs. I didn't notice the error, Google Play Console did it on the release. I will try 8.6.2 now.

snorrsi · 2021-11-22T13:30:03Z

@naklow12 Are you able to reproduce this problem easily? Did you see any improvements with 8.6.2 ?

naklow12 · 2021-11-22T19:03:35Z

Yes it's solved.

paulinon · 2021-11-24T08:55:08Z

Hey @Jack37, could you try out version 8.6.2 of the SDK and see if the issue persists? I tested this with @aroman's sample project, and the error messages don't appear anymore.

iningwei · 2021-11-25T11:26:57Z

I am sure it is the same as this bug which i have metioned 1-2month ago (i used firebase sdk v-8.3.0).
The first time you launched app after installation, the crash is caused by fcm auto init,if you have no internet connect or can not connect to google,it will crash.
In the link above i have made some rectify buy @Otarius0 's suggestion.It works a lot,but still have chance to crash.

TBarendt · 2021-11-25T13:09:55Z

@iningwei the bug fix was for shutting down messaging. Yours looks like during startup? I had a quick look at the code and I think there might be an issue there as well. I had put in a pull request to see what the devs thinks. firebase/firebase-cpp-sdk#760

kolobokspb · 2021-11-27T12:09:43Z

@paulinon , @TBarendt , @snorrsi
8.1.0 - ок
8.5.0 - crashing
8.6.1 - crashing
8.6.2 - the application stopped crashing

kolobokspb · 2021-11-29T21:39:14Z

@paulinon , @TBarendt , @snorrsi
I was not happy for long.

After upgrading to version 8.6.2, my app stopped crashing. )
But GooglePlayGames v0.10.12 stopped working. (

Only after updating GooglePlayGames to version v0.10.13 did it work.

That's not all, after installing the plugin GooglePlayGames and ExternalDependencyManage v0.10.13 Unity began to crash due to ExternalDependencyManage when installing the plugin and every time Unity was loaded. So I took the ExternalDependencyManager that comes with Firebase.
