If using CocoaPods for Apple platforms, the project's Podfile.lock

Expand Podfile.lock snippet

👀 Replace this line with the contents of your Podfile.lock!

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

Hey @UnwindGamesDeveloper, sorry for the delayed response here. Could you share with me what Firebase products are you using? Also is there any chance you could share steps to reproduce the behavior or a minimal reproducible example? It'll help speed up our investigation. Thanks!

HI @argzdev , It's been a while , so haven't updated firebase sdk since (still on 12.4.1).
We are using only Analytics and Crashlytics.

What we want is to control the initialization of firebase (in our unity game )from C# side. Hence, wanted to remove node from manifest like this:

<provider android:name="com.google.firebase.provider.FirebaseInitProvider" android:authorities="${applicationId}.firebaseinitprovider" tools:node="remove" />

And on unity side , somthing like this:

            `if (dependencyStatus == DependencyStatus.Available)
            {

#if SOME_PREPROCESSOR
AppOptions options = null;

                options = new AppOptions
                {
                    ApiKey = "OurKey"
                    AppId = "123456789",
                    ProjectId = "project-id"
                };


                firebaseApp = FirebaseApp.Create(options);
                
                Crashlytics.ReportUncaughtExceptionsAsFatal = true;

#endif

            }`

When doing this at runtime we were getting this exception :

java.lang.IllegalStateException: FirebaseApp was deleted

Thanks for providing code snippets, @UnwindGamesDeveloper. So far, I'm unable to reproduce the same behavior. I used our Firebase quickstart Unity for Crashlytics and added the similar code snippet with your setup. The Firebase Console was able to display the crashes being sent from the app. I don't see any runtime issue of java.lang.IllegalStateException: FirebaseApp was deleted.

Code snippet I have is fairly similar to yours:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools">
  <application>
    <provider android:name="com.google.firebase.provider.FirebaseInitProvider" android:authorities="com.google.firebase.unity.crashlytics.testapp.firebaseinitprovider" android:exported="false" tools:node="remove" />
    <!--Used when Application Entry is set to Activity, otherwise remove this activity block-->
    <activity android:name="com.unity3d.player.UnityPlayerActivity" android:theme="@style/UnityThemeSelector">
      <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>
      <meta-data android:name="unityplayer.UnityActivity" android:value="true" />
    </activity>
    <!--Used when Application Entry is set to GameActivity, otherwise remove this activity block-->
    <activity android:name="com.unity3d.player.UnityPlayerGameActivity" android:theme="@style/UnityThemeSelector">
      <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>
      <meta-data android:name="unityplayer.UnityActivity" android:value="true" />
      <meta-data android:name="android.app.lib_name" android:value="game" />
    </activity>
  </application>
</manifest>

   public virtual void Start() {
      FirebaseApp.CheckAndFixDependenciesAsync().ContinueWithOnMainThread(task => {
        dependencyStatus = task.Result;
        if (dependencyStatus == DependencyStatus.Available) {
          InitializeFirebase();
        } else {
          Debug.LogError(
            "Could not resolve all Firebase dependencies: " + dependencyStatus);
        }
      });
    }

    void InitializeFirebase() {
      Firebase.AppOptions appOptions = new Firebase.AppOptions
      {
        ApiKey = "AIzaxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxZQ",
        AppId = "1:700000000000000:android:0000000000000002",
        ProjectId = "xxxxx-xxxxxxx-xxxxxxx"
      };

      var app = Firebase.FirebaseApp.Create(appOptions);
      firebaseInitialized = true;
    }

I'm currently using the latest version of Firebase 12.5.0 and Unity Editor 6000.0.34f1, not sure if that makes any difference. Am I missing anything?

[UnwindGamesDeveloper]

@argzdev Yes , this exact same setup was leading to the issues mentioned earlier. Although i was on 12.4.1. I'll update to 12.5.0 and confirm on it again.

Will update this in a while.

[argzdev]

In that case, there could be a different configuration that is causing this issue. If you're still encountering the issue, please provide us an MCVE so we can investigate this further. Thanks!

[UnwindGamesDeveloper]

Also additional info , which i forgot to add initially (My bad! ) is that this execption "java.lang.IllegalStateException: FirebaseApp was deleted." was never caught by crashlytics itself. We also have integrated Bugsnag as a secodary soruce for tracking exceptions . It was bugsnag which was catching this exception.

[argzdev]

Thanks for the additional info. That said, we still need an MCVE to investigate this further since we're unable to reproduce this behavior on our side.

From my understanding, the error "java.lang.IllegalStateException: FirebaseApp was deleted" means that the default Firebase app instance already exist and is being replaced which causes to throw this issue. You could be running an instantiation code more than once.

FYI, Firebase Analytics cannot function by manual instantiation. This is still an open feature request in our Firebase Android SDK repo. There are a couple of suggestion by other developers as alternative solution, however we don't have any official guide for that as of the moment.

"From my understanding, the error "java.lang.IllegalStateException: FirebaseApp was deleted" means that the default Firebase app instance already exist and is being replaced which causes to throw this issue. You could be running an instantiation code more than once."

Yeah from my end , will double check on this part as well.

Also would give a thorough MCVE if i still encounter it.

Thanks for quick responses @argzdev !
