What it is
An 11-minute Android tutorial from the slidenerd channel (part 3 of a swipe tabs series). It adds a ViewPager to MainActivity, sets a FragmentPagerAdapter or FragmentStatePagerAdapter, uses getItem to supply fragments, and uses OnPageChangeListener to keep the ActionBar tabs and the ViewPager in sync.
