Error firebase Failed to read Firebase options from the app's resources. Either make sure google-services.json is included in your build or specify options explicitly.

Firebase does not generate the Plugins/Android/FirebaseApp.androidlib & FirebaseCrashlytics.androidlib folders so there is no values/google-services.xml file.

I copied these files from an older install of firebase (2020) and it worked.

Steps to reproduce:

Have you been able to reproduce this issue with just the Firebase Unity quickstarts (this GitHub project)?
What's the issue repro rate? (eg 100%, 1/5 etc)

100% repo rate.
Fresh 2021 and 2022 LTS projects.

Add google-services.json and GoogleService-Info.plist to root /Assets/ folder

Import Analytics and Crashlytics unitypackage (downloaded latest from firebase site)

Resolve dependencies in dependency resolver.

Add the sample init code and crashlytics test code (from docs)

Build .apk

Check Logcat

What happened? How can we make the problem occur?
This could be a description, log/console output, etc.

If you have a downloadable sample project that reproduces the bug you're reporting, you will
likely receive a faster response on your issue.

I believe it is related to this:

Sometimes it works and loads properly (which will allow the required google-esrvices.xml files to be generated).
But I'm not sure why this is happening.

Assembly 'Assets/Firebase/Editor/Firebase.Editor.dll' will not be loaded due to errors:
Unable to resolve reference 'UnityEditor.iOS.Extensions.Xcode'. Is the assembly missing or incompatible with the current platform?
Reference validation can be disabled in the Plugin Inspector.

Assembly 'Assets/Firebase/Editor/Firebase.Crashlytics.Editor.dll' will not be loaded due to errors:
Unable to resolve reference 'UnityEditor.iOS.Extensions.Xcode'. Is the assembly missing or incompatible with the current platform?
Reference validation can be disabled in the Plugin Inspector.

Seems that installing iOS build support to my 2022.3 install allowed me to build and confirm that analytics/crashlytics worked.
However it didn't generate the required google-services.xml file. See here: googlesamples/unity-jar-resolver#412 (comment)

In 2021.3 I was able to get those generated and copied it to my 2022.3 project so it worked as a "fix".

Hi @xjjon

Odd that it is still failing to generate the xml file. I assume there are no errors or anything useful in the logs? The script/executable that should do that is in Assets/Firebase/Editor, generate_xml_from_google_services_json.exe (or .py). If you try running that directly, does that give any helpful info?

hi @a-maurice

I tried to run the .exe (didn't seem to do anything)

Tried to run the python script next. Initially it gave errors:

python Firebase/Editor/generate_xml_from_google_services_json.py
Traceback (most recent call last):
  File "E:\MyProject\Assets\Firebase\Editor\generate_xml_from_google_services_json.py", line 498, in <module>
    sys.exit(main())
             ^^^^^^
  File "E:\MyProject\Assets\Firebase\Editor\generate_xml_from_google_services_json.py", line 355, in main
    with open(input_filename, 'r') as ifile:
         ^^^^^^^^^^^^^^^^^^^^^^^^^
FileNotFoundError: [Errno 2] No such file or directory: 'app/google-services.json'

Wasn't sure the arguments to run it with so i just moved my google-services.json to the default app/google-services.json location.

Ran it again from root /Asset/ folder and it produced the and res/values/google-services.json but in the wrong output directory. (it puts it in the directory i run it from)

The values generated by the .py are correct though (I compared it to the values in downloaded .json)

Another issue I noticed is the crashlytics_build_id.xml doesn't get updated. I wasn't able to find out where this is updated from.
