Hey @Lesmannn, thanks for reaching out. It looks like you're using an old version (September 27, 2022) of our Firebase SDK. That said, I'd recommend updating to the latest Firebase Unity SDK version 12.7.0. Please note that this also requires using Unity 2021.3.43f1 or later.

This is for us to avoid issues that might've been fixed in the most recent versions.
Let me know if it helps. Thanks!

Hey @argzdev thank you for your reply, i already upgrade the firebase version to 12.7.0 and also upgrade my unity version to 2022.3.60f LTS. That error is solve, but it show new error like this :

2025/03/21 08:18:30.636 15756 15805 Error Unity DllNotFoundException: Unable to load DLL 'FirebaseCppApp-12_7_0'. Tried the load the following dynamic libraries: Unable to load dynamic library 'FirebaseCppApp-12_7_0' because of 'Failed to open the requested dynamic library (0x06000000) dlerror() = dlopen failed: library "FirebaseCppApp-12_7_0" not found

I already try to solve this with different way but all of my way seem fail and still show this error. Im already try :

1. Force Resolve on Android Resolver
2. Uninstall Firebase & External Depedency Manager and Install it again with latest version
3. Delete unity library and re-open unity
4. Using BoM on mainTemplate.gradle
5. Tried enabling 'any platform' for all FirebaseCppApp-12_7_0 files
6. Change higher min sdk version (23 > 24)

any help about this ?

Using BoM on mainTemplate.gradle

AFAIK, you don't need to do this. Importing the dependencies as usual should work as is. But it does looks like the imports somehow weren't added properly. Could you try Assets > Reimport all and see if that changes anything? I tried our Firebase Firestore testapp but so far haven't encountered any issues. You can also check that out for reference.

That said, if the issue is still persistent, could you provide an MCVE so we can investigate this further?
