Otto - post a message between activity lifecycle

I'm studying a way to handle activity lifecycle and retain the state/progress of users app, then I found the otto/eventbus solution.

But after some research i can't figure out how to handle a particular case. So, what happens if my worker thread (async) finishes between the onpause/oncreate of my activity/fragment, it won't deliver the data? I'm trying to find an answer or create a project to test this, but just with my tests i can't be sure.

Am I missing something or the bus won't deliver the data? If it won't deliver the result how to handle that?

Sorry for my awful english.

Events are only passed to subscribers that are active at the time of posting.

To deliver an event to subscribers later on, store the object you're posting to a model object of sorts and add a @Produce getter for it. When a new subscriber for that object is registered, it gets its initial event from this @Produce getter.
