Summary
In this chapter, we completed the development of the Messenger Android application. In the process of doing so, we learned how to make use of ChatKit—a third-party library for creating beautiful chat user interfaces. In addition to this, we further explored the utilities offered to us by the Android application framework. We got a firsthand look at the development of a settings activity in Android, which helped us to learn about PreferenceScreen, PreferenceActivity, DialogPreference, Preference, and PreferenceFragment. Finally, we briefly discussed Android application testing and performing background operations.
In the next chapter, we will explore the various storage options provided to us by the Android application framework.
