Android how to efficiently implement data caching and configuration change events in fragments?

Question

I'm confused in finding a better way to implement:

1) data caching, as I am fetching data from rest APIs by executing AsyncTask in every fragment say 3-4 times, what I want is to reload the data from cache instead of calling the AsyncTask again.

2) a way to deal with configuration changes events... such as orientation change or some other events.

confusion: are DATA Caching and onconfiguration changes related at all somehow? If so, does only caching code can serve the purpose for both issues?

What I've tried : here's a project that does the magic for onconfiguration changes part and this library project can serve the data caching purpose

or should i use the volley library as recommended in google io 2013?

My MODEL: I am having 1 ACTIVITY that controls and seven other specific fragments that does the execution part. Please type your words if you've any kind of idea how to proceed?

Loaders may totally satisfy your needs. If not, consider using LruCache.
