I know that a fragment’s view hierarchy has to be inflated in onCreateView, but what other functionality can be in onCreateView vs. what should wait for onActivityCreated? My current implementation uses separate activities for everything, and a typical activity does most of its work in its onCreate method, including inflating the view, setting the content view, initializing the various widgets with data, setting up listeners, etc.

So can this probably all be moved into onCreateView, or should some functions be put into an onActivityCreated method instead?

    If your view is static, then moving any code to the onActivityCreated method is not necessary. But when you – for instance, fill some lists from the adapter, then you should do it in the onActivityCreated method as well as restoring the view state when setRetainInstance used to do so.

    Also accessing the view hierarchy of the parent activity must be done in the onActivityCreated, not sooner.
