Implementation of PagerAdapter class from the Android compatibility package that uses a Fragment to manage each page. This class also handles saving and restoring of fragment's state.
This version of the pager is more useful when there are a large number of pages, working more like a list view. When pages are not visible to the user, their entire fragment may be destroyed, only keeping the saved state of that fragment. This allows the pager to hold on to much less memory associated with each visited page as compared to FragmentPagerAdapter at the cost of potentially more overhead when switching between pages.
From the documentation of the FragmentStatePagerAdapter class:

Subclasses only need to implement
