Xamarin.Forms Projects - Second Edition

Overview of this book

Xamarin.Forms is a lightweight cross-platform development toolkit for building apps with a rich user interface. Improved and updated to cover the latest features of Xamarin.Forms, this second edition covers CollectionView and Shell, along with interesting concepts such as augmented reality (AR) and machine learning. Starting with an introduction to Xamarin and how it works, this book shares tips for choosing the type of development environment you should strive for when planning cross-platform mobile apps. You’ll build your first Xamarin.Forms app and learn how to use Shell to implement the app architecture. The book gradually increases the level of complexity of the projects, guiding you through creating apps ranging from a location tracker and weather map to an AR game and face recognition. As you advance, the book will take you through modern mobile development frameworks such as SQLite, .NET Core Mono, ARKit, and ARCore. You’ll be able to customize your apps for both Android and iOS platforms to achieve native-like performance and speed. The book is filled with engaging examples, so you can grasp essential concepts by writing code instead of reading through endless theory. By the end of this book, you’ll be ready to develop your own native apps with Xamarin.Forms and its associated technologies, such as .NET Core, Visual Studio 2019, and C#.

Project overview

Many apps can be made richer by adding a map and location services. In this project, we will build a location tracking app that we will call MeTracker. This app will track the position of the user and save it to a SQLite database so that we can visualize the result in the form of a heat map. To build this app, we will learn how to set up processes in the background on both iOS and Android since we cannot share code between iOS and Android. For the map, we will use the Xamarin.Forms.Maps component and extend its functionality in order to build a heat map. To do this, we will use a custom renderer for iOS and a custom renderer for Android so that we can use the platform's APIs.

The estimated build time for this project is 180 minutes.
