Code your first Xamarin.Android app: create a project, define the UI, and implement behavior.
Implement multi-page Xamarin.Android apps using Activities and stack navigation.
Code your first Xamarin.iOS app: create a project, define the UI, and implement behavior.
Reduce the amount of code you must write by sharing your business logic across platforms.
Xamarin.Forms lets you define a single UI that you share across all your supported platforms. This maximizes your ability to share code: you can share your UI and your business logic. In this course, you will create a new Xamarin.Forms application and define your shared UI in code. You will also see how to access platform-specific features such as the phone dialer or camera that do not have a shared-programming model integrated into Xamarin.Forms.
Xamarin.Forms lets you define your UI using the eXtensible Application Markup Language (XAML). This gives you a clean separation of UI and behavior and makes it easy to utilize a design expert and design tools. This course shows you how to define your UI in XAML. You will create pages and add controls, all in markup. You will also see how to access UI elements from code so you can subscribe to UI events and update UI properties as your data changes.
Xamarin.Forms apps run on a wide range of devices with varying screen sizes and pixel densities. It is challenging to create a UI that looks good and behaves correctly in all cases. Xamarin.Forms helps solve this problem by providing flexible layout containers that can calculate the size and position of your UI controls automatically; they even recalculate if the user rotates the device or changes the size of the app’s window. This course contains in-depth coverage of StackLayout and Grid, the two most popular layout containers in Xamarin.Forms. It also shows you how to add scrolling when your UI is too large for the available screen area.
Users expect to access their information any time from any location using any device. This leads most app developers to store data in the cloud and retrieve it as needed from client devices. REST-based web services are the dominant strategy for this type of device-to-server communication. In this course, you will see how to consume REST-based web services with HttpClient using both the managed networking stack and the platform-specific handlers that boost performance. You will also learn some common strategies for dealing with the unique challenges that mobile devices face when communicating over the network.
Many apps need to store data locally on the device so it is available even when network access is unreliable. User preferences, data files, and relational data can all fall into this category. This course starts with a survey of the local-storage options available to you in your Xamarin applications. It then concentrates on storing relational data using a SQLite database. By the end of the course, you will have seen how to identify the proper location for your database file and how to insert, update, retrieve, and delete data efficiently using asynchronous I/O calls.
Use Data Binding in Xamarin.Forms to connect your application’s data to your UI.
Use the Xamarin.Forms ListView control to display scrolling lists of interactive data.
Learn common architectural principals and styles to properly structure your mobile app.
Xamarin.Forms UI elements are model objects that are converted to native platform controls at runtime. To take full advantage of each platform’s unique style and patterns you can work directly with the native controls rather than the Xamarin.Forms elements. This course shows you how to use Effects to access and customize the native peer controls. This gives you the same power to modify the appearance of your UI as a native developer.
