Is it possible to put a fragment inside a fragment in Android? Consider this: Say, I implement swipeable tabs using Fragment and ViewPager. Now, inside each of these swipeable fragments, I want to implement another fragment - kind of like a fragment nested inside another fragment. But a fragment needs to be attached to an Activity class. So how can this be done?

Using the Android Support package's backport of fragments, yes. Also, native fragments on Android 4.2 and higher (API Level 17+) support nested fragments. However, native fragments from API Level 11-16 do not.

This sample project demonstrates having fragments in a ViewPager and having the ViewPager itself be in a fragment. The key is that the FragmentManager you supply to your FragmentPagerAdapter must be the child fragment manager of the outer fragment (i.e., getChildFragmentManager()).
