In this chapter, we started by going over the basic settings in the Android Manifest file. Next, we implemented a custom Application class for setting up our ServiceContainer. We then went over the different types of Android layouts and implemented a login screen using native Android views. Next, we set up a menu in the Android action bar by using an Android layout and overriding a few built-in methods. We implemented the friends list screen, and learned the basics of ListView and adapters. Finally, we implemented the messages screen, and used the more advanced functionality available in list view adapters and layouts.

Upon completing this chapter, you will have a partially functional Android version of XamChat. You will have gained a deeper understanding of the Android SDK and tools. You should be confident on developing your own Android applications using Xamarin. Take it upon yourself to implement the remaining screens that we did not cover in the chapter. If you get lost, feel free to review the full sample application included with this book. In the next chapter, we'll cover how to deploy to mobile devices and why is it very important to test your applications on real devices.
