Is there something special when running baselineProfileGeneration about dependencies in the main app?

[Tolriq]

The app works fine with alpha 4 but when trying to generate the baseline it crash with:

Ok so occurs on release builds too, probably a mix of things with R8 😞 Too late to debug now.

[Ben Trengrove [G]]

This looks like a bug in the new focus modifier code. Could you please file an issue with that stacktrace and any reproduction steps?

[Tolriq]

That's the plan for today.

So this is an R8 full mode issue or at least they will provide the info if some new rules are needed. Reported as https://issuetracker.google.com/issues/265188224
