Hello! Wanted to provide some updates on my end.

I don't think that this is an issue with specifically this version of Firebase - I did some more digging & found that this error persists across different versions. Here is my results:

• Test 1:
  • Upgrade to latest version of Firebase (12.6.0) & EDM4U (1.2.185)
  • Build on MacOS (Silicon) to Android (to Apk)
  • Result: Still got the same Gradle error
• Test 2:
  • Downgrade to Firebase 12.4.1 & EDM4U 1.2.183
  • Build on MacOS (Silicon) to Android (to Apk)
  • Result: Still got the same Gradle Error

Has the team looked at the error yet? Also is there any additional context that may help? Thanks!

Hey @jkorn2324, thanks for providing complete details. I tested our Firebase Unity quickstart with all the products you've listed: Analytics, Messaging, App, Auth, Firestore but so far I wasn't able to reproduce the same behavior.

Looking at the stacktrace you've provided, there's 3 errors:

1: Execution failed for task ':launcher:checkReleaseDuplicateClasses'.
2: java.lang.StackOverflowError (no error message)
3: Execution failed for task ':unityLibrary:generateReleaseRFile'.

There's a thread in the Unity forum that listed down quite a few solutions that could help with the error of checkReleaseDuplicateClasses. Could you try Assets → Play Services Resolver → Android Resolver → Delete Resolved Libraries and see if that changes anything?

As for the other errors, these could be consequential errors from the initial error checkReleaseDuplicateClasses.

Let me know what happens. Thanks!

Hey thanks for getting back to me!
Just tried it out & here is what I did when using EDM4U 1.2.183 & Firebase 12.5.0:

• Close Unity, Delete Library Folder, & Re-Open
• Clicked Assets -> External Dependency Manager -> Android -> Delete Resolved Libraries:
  • Deletes Assets/GeneratedLocalRepo Folder
  • Modifies mainTemplate.gradle & settingsTemplate.gradle (deleting Dependencies)
• Made an Apk Build
  • Build was successful, however when I ran it I get a dllnotfound exception for Firebase

I mainly get these errors after I run Assets -> External Dependency Manager -> Android -> Force Resolve. However, when I ran this using EDM4U in 1.2.181 & Firebase 12.1.0 on Unity 2022.3.20f1 I was able to successfully build & run the apk without the dllnotfound exception. Is there anything that I'm missing?

Also I wanted to ask if you were installing Firebase & EDM4U directly into the Assets folder using a .unitypackage or by installing each product into the Packages folder using an unzipped .tgz file?

Thanks for the extra details, @jkorn2324. It looks like the issue isn't present on Android 14 devices or lower. I was able to reproduce the error when testing on Android 15 emulator. Might be an issue similar to firebase/firebase-unity-sdk#1180.

In my case, the app opens for a short while, then crashes after a few seconds.

Stacktrace of the error:

Also I wanted to ask if you were installing Firebase & EDM4U directly into the Assets folder using a .unitypackage or by installing each product into the Packages folder using an unzipped .tgz file

On either option, using .unitypackage or .tgz files both works when testing on Android 14. Both option also fails when testing on Android 15.

I'll bring this up to our engineers and see what we can do here.

Okay that sounds great thanks for investigating the .dllnotfound exception. Keep me posted on what your team finds!

[jkorn2324]

Okay, I did even more digging and have some more updates:

• I found the issue with why I was getting the checkReleaseDuplicates gradle errors:
  • Whenever I run Assets -> External Dependency Manager -> Android -> Force Resolve, the settingsTemplate.gradle file wouldn't update the maven paths to the directories where the .aar files are located:
    • Maven directories would be set to url = (unityProjectPath + "/Packages/Google/{path_to_m2repository}") (where the .srcaar files are)
    • The Maven directories should be set to url = (unityProjectPath + "/Assets/GeneratedLocalRepo/{path_to_m2repository}") (where the .aar files are)
  • The checkReleaseDuplicates task would fail because the dependencies wouldn't be found in the maven directories.

On EDM4U 1.2.181, it would set the directory root to match the Assets/GeneratedLocalRepo even with the way my project was set up. I believe that it's due to a change with how Force Resolve works.

The fix ideally would be that if users ran Force Resolve and EDM4U successfully placed the .aar files into the Assets/GeneratedLocalRepo folder. the settingsTemplate.gradle file would be updated so that the maven directories match: url = (unityProjectPath + "/Assets/GeneratedLocalRepo/{path_to_m2repository}"), no matter where the original Firebase packages were located in Unity.

For the .dllnotfoundexception, I haven't looked into that yet either as I built with Android 14. Do you have any updates on that?
Also what are your thoughts on the issue & potential solution to the checkReleaseDuplicates gradle error?
