Android Question Failed resolution of: Landroidx/work/impl/WorkDatabase

[Filippo]

Hi,

despite using this Android code snippet, I still have the error in my app!
Is there anything else I can try?

Fatal Exception: java.lang.NoClassDefFoundError
Failed resolution of: Landroidx/tracing/Trace;

This class belongs to androidx.tracing:tracing.

#AdditionalJar: androidx.tracing:tracing

Which libraries are you using? I will add the missing dependency?

Hi Erel,
That's all the app uses.

 

[Erel]

I've updated FirebaseAdMob2 and FirebaseAuth with this dependency.

Thank you very much, Erel!

Hi,

unfortunately, other errors continue to occur.
After recompiling my app with the two new libraries “FirebaseAdMob2 and FirebaseAuth,” I now get this error:

This one should be fixed with FirebaseAnalytics v3.21: https://www.b4x.com/android/forum/threads/firebaseanalytics.67708/post-1031026
