Can you provide an example of how this scenario would work?

I have a good reason why all the business logic is in the first
Fragment, and why it should not be spread among 3 DialogFragments
(since there are 3 dialogs).
The Fragment needing to show the Dialog is a "Worker" Fragment without
a UI. It is used by several Activities. It contains a complex state
machine which receives many asynchronous inputs.
The actions of each of the 3 AlertDialogs are also inputs to this
state machine. The machine should remain encapsulated in the Worker
Fragment, Activities using the Worker Fragment should not need to know
about it.
