Android: onRetainNonConfigurationInstance() deprecated?

Question

Inside my Activity I am instantiating an object which is responsible to query, process and store the data needed by the fragments. I was about to use onRetainNonConfigurationInstance() in order to retain the object after configuration changes, but I just realized the method has been deprecated.

I can see that the new recommended way is to use Fragment's setRetainInstance() , but it doesn't look like it's what I need, because my object doesn't deal with just 1 fragment.

Do you have any suggestions?

No, but your fragment can deal with whatever the object is.

onRetainNonConfigurationInstance() requires you to package everything into one object. Consider the retained fragment strategy to be requiring that this "one object" be a fragment, on which you call setRetainInstance() . Anything you could do with onRetainNonConfigurationInstance() should be doable with a retained fragment.
