14.6. Wrap-Up

In this chapter, we presented the Weather Viewer app and its companion app widget. The app used various features new to Android 3.x.

You learned how to use fragments to create and manage portions of the app’s GUI. You used subclasses of Fragment, DialogFragment and ListFragment to create a robust user interface and to take advantage of a tablet’s screen size. You learned that each Fragment has a life cycle and it must be hosted in a parent Activity. You used a a FragmentManager to manage the Fragments and a FragmentTransaction to add, remove and transition between Fragments.
