By: Jonathan Peppers

Overview of this book

Xamarin is a leading cross-platform application development tool used by top companies such as Coca-Cola, Honeywell, and Alaska Airlines to build apps. Version 4 features significant updates to the platform including the release of Xamarin.Forms 2.0 and improvements have been made to the iOS and Android designers. Xamarin was acquired by Microsoft so it is now a part of the Visual Studio family. This book will show you how to build applications for iOS, Android, and Windows. You will be walked through the process of creating an application that comes complete with a back-end web service and native features such as GPS location, camera, push notifications, and other core features. Additionally, you’ll learn how to use external libraries with Xamarin and Xamarin.Forms to create user interfaces. This book also provides instructions for Visual Studio and Windows. This edition has been updated with new screenshots and detailed steps to provide you with a holistic overview of the new features in Xamarin 4.

Summary


In this chapter, we started out 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 XamSnap. You will have gained some deeper understanding of the Android SDK and tools. You should be confident in developing your own Android applications using Xamarin. Take it upon yourself to implement the remaining screens that we did not cover in this chapter. If you get lost...
