IncompatibleClassChangeError with androidx.work.logger

We have updated android.arch.work:work-runtime:1.0.0-beta01 and we are getting a lot of crashes on clients:

The method 'void androidx.work.Logger.debug was expected to be of type static but instead was found to be of type virtual at androidx.work.impl.background.firebase.FirebaseJobService.onStartJob(FirebaseJobService.java:65)

Seems to be an internal problem in AndroidX / FirebaseJobService. We are getting reports from clients and Crashlytics (for now 100% on android 5.0)

build.gradle:

We are getting the following stack trace:

Solution

  • You are mixing WorkManager (beta01) and the optional Firebase dependency (alpha11). You can't mix versions (see https://issuetracker.google.com/issues/122028782). The Firebase dependency has been deprecated, so you should remove it entirely.
