I was using WorkManager with a configuration that injects a HiltWorkerFactory so the individual workers can in-turn inject things they need (e.g., DAOs).

This was working fine, no lint errors.

I modified this to move the WorkManager initialisation to an androidx.startup.Initializer.

This works with no problem, as expected -- e.g., WorkManager.initialize() documentation is explicit that this method can be called in a content provider.

However, the BadConfigurationProvider lint error only checks to see if the Application implements Configuration.Provider, and doesn't check content providers. This is a fatal lint error.

It's a reasonable limitation of the lint check, but the error message is overly specific. It's currently:

An android.app.Application must implement androidx.work.Configuration.Provider for on-demand initialization.

If the rest of the documentation is correct the "must" in that error is too strong. A better error message might be:

The android.app.Application does not implement androidx.work.Configuration.Provider. If it is not implemented here, or in a content provider, on-demand initialization will not work.

and the severity should probably be warning.

https://github.com/pachli/pachli-android/pull/762 is the change where I switched to androidx.startup with HiltWorkerFactory.
