Summary

The shift from the old thinking of being activity-oriented to the new thinking of being fragment-oriented opens our applications up to rich possibilities. Fragments allow us to better organize both the appearance of the user interface and the code we use to manage it. With fragments, our application user interface has a more modular approach that frees us from being tied to the specific capabilities of a small set of devices and prepares us to work with the rich devices of today, and the wide variety of new devices to come tomorrow.

In the next chapter, we'll build on the modularized user interface we've created with fragments to enable our application to automatically adapt to differences in the various device form factors with only minimal changes to our application.
