[Question] Firebase - NoClassDefFoundError at startup

[rossojr92]

What is your question?

Hi We are experiencing an issue with Firebase 11.8.1. We are building aab with multidex and split application binary enabled.

The build seems to crash at startup with this error:

java.lang.NoClassDefFoundError: Failed resolution of: Lcom/google/android/gms/common/internal/Preconditions; at com.google.firebase.provider.FirebaseInitProvider.checkContentProviderAuthority(FirebaseInitProvider.java:85)

I leave here a screenshot with more information about the log. Is anyone experiencing this issue?

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

Hey @rossojr92, thanks for reaching out. NoClassDefFoundError is usually caused by unable find a class definition on runtime, meaning there was an issue during the compilation. I'm suspecting that the issue might be a conflict in the dependencies. Could you try the solution in #927 and #688?

Let me know if that helps. Thanks!

Hi for sure it's something in dependencies. Regarding the #927 and #688: #927 --> this is a compilation problem. Our build phase is fine. Our crash happen at runtime #688 --> The solution here seems to enable Custom Main Gradle Template and Custom Gradle Properties to properly resolve dependencies conficts.

Unfortunately, we are already using Custom Main Gradle Template and Custom Gradle Properties. The resolution phase is succeeding all the time.

Does it exists a way to log conflicts or something similar during dependencies resolution?

We might need to dig deeper, could you provide an MCVE? Thanks!
