I guess technically, the ProGuard rule should be on androidx.work.NonBlockingWorker subclasses, but I'd also be okay with just not using reflection to access the Worker(Context, WorkerParamters) constructor and skipping the need for a ProGuard rule at all.

I tried to use the ProGuard configuration which is linked in

comment #3

in my project.
The release build fails and the following warnings are printed:

22:22:06.567 [QUIET] [system.out] Note: the configuration keeps the entry point 'androidx.work.NonBlockingWorker { NonBlockingWorker(android.content.Context,androidx.work.WorkerParameters); }', but not the descriptor class 'androidx.work.WorkerParameters'
22:22:06.567 [QUIET] [system.out] Note: the configuration keeps the entry point 'androidx.work.NonBlockingWorker { void internalInit(android.content.Context,androidx.work.WorkerParameters); }', but not the descriptor class 'androidx.work.WorkerParameters'
22:22:06.567 [QUIET] [system.out] Note: the configuration keeps the entry point 'androidx.work.Worker { Worker(android.content.Context,androidx.work.WorkerParameters); }', but not the descriptor class 'androidx.work.WorkerParameters'

The app is opensource if you want to run the release build yourself. Here is the branch (WIP):

Please run: ./gradlew --info --debug aCcc34c3Release
