Course Description

In this course students will learn how to use Xamarin as a cross-platform mobile development tool to build native Android and iOS apps using C# and a .NET code base.

Students will begin by learning how to use Xamarin.Forms to build Android and iOS apps using a single code base. Students will learn how to use XAML to define the UI layer for all platforms. By installing the app on both Android and iOS simulators and real test devices, they will see how the UI renders as native controls on each platform, thereby giving the app a native look and feel.

Coverage of XAML includes how to use XAML controls to interact with the use, how to use XAML to manage the UI layout, and how to connect UI events to C# event handlers. Students will also learn how to custom the UI appearance of an app for a specific platform.

Students will learn how to interact with both local data stored on the device and how to communicate with, and process data from, RESTful services using Xamarin.Forms.

Xamarin also supports Xamarin Native, which allows developers to write separate native UI code for each platform. In this course, students will learn how to install and configure Xamarin.Android, and then examine Android application architectures. They will build Android applications in C# using Xamarin.Android using the Android designers and controls.

Students will also learn how to install and configure Xamarin.iOS, and then examine native iOS application architectures. Students will build Xamarin.iOS applications in C# using the iOS designers and controls.

This course will also examine how to work with touch and location services for both Android and iOS devices.
