We are seeing `IllegalStateException`s in the play store from calling `findNavController` when the fragment is not associated with a transaction (the parentFragmentManager is null) `isAdded()` is the recommended way to find out if this fragment is attached to an activity and `findNavController()` is safe to call NB this fix is based on static analysis only - plan is to keep an eye on the crash logs after it lands to confirm it works.

Do we need to do anything when the fragment is not added? Log an error with some state?

it's a good question, but i don't think so - suspect nobody would care about this error, and it would just create noise in the logs. |
