Updating to Firebase BOM 33.8.0

[wvdans6225]

Android Studio version: 2024.2.2
Android Studio build: #AI-242.23726.103.2422.12816248, built on December 17, 2024
Component: Firebase Analytics
Component Version: I have not been specifying a version per documentation.

I tried updating Firebase BOM to version 33.8.0 this morning because Android studio reported an available update, and when I build my app I get an error indicating that com.google.firebase.analytics.analytics in imports and the Firebase.analytics call now both generate Unresolved Reference errors and the build fails.

To mitigate this problem I rolled back to version 33.7.0, and my app compiled without issue.

I noticed that the documentation for implementing Firebase and Firebase analytics found at https://firebase.google.com/docs/android/setup still indicates that 33.7.0 should be used.

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

I am running into the exact same problem.

Android Studio version: 2024.2.2
Android Studio build: #AI-242.23726.103.2422.12816248, built on December 17, 2024
Component: Firebase Analytics
Component Version: I have not been specifying a version per documentation.

When I updated Firebase BOM to version 33.8.0 (com.google.firebase:firebase-bom) my app would not finish building. Same error as the original reporter, indicating that com.google.firebase.analytics.analytics in imports and the Firebase.analytics call now both generate Unresolved Reference errors and the build fails.

I rolled back to version 33.7.0, and my app built without issue.

I have the same problem too. 😅 Updating from 33.7.0 to 33.8.0 break the build as @pmechenbier and @wvdans6225 already pointed out.

Hi folks! I tried reproducing the issue using the Android quickstart app for Google Analytics, however, I wasn't able to reproduce the issue.

Can you share the repositories, plugins and dependencies you're using? Also, could you try clearing the cache and see if that helps?Thanks!

Tried clearing all caches as first troubleshooting step, before submitting this ticket.

Note: I tried again this morning and pulled the attached screenshots.
Rollback to 33.7.0 again allowed successful build.

Hi all, changing kotlin version to 2.1.0 fixed this issue.

[lehcar09]

Thank you for the details @wvdans6225. I was able to encounter the error.

The root cause, based on the logs, is an incompatible Kotlin version. Your project uses Kotlin 1.9.~, but the "play-services-measurement-api" (Google Analytics dependency) requires Kotlin 2.1.0.

Specifically, the following error appeared:

> Task :app:compileDebugKotlin
...gradle/caches/8.12/transforms/0a0c765d953f98b5c42cc5530554352a/transformed/play-services-measurement-api-22.2.0-api.jar\!/META-INF/java.com.google.android.gmscore.integ.client.measurement\_api\_measurement\_api.kotlin\_moduleModule was compiled with Kotlin 2.1.0, but version 1.9.0 was expected.

The issue was resolved after updating the Kotlin version to 2.1.0.

With that, I’ll be closing this issue now. Let me know if there’s any misunderstanding so we can reopen the issue. Thanks!
