Android Fundamentals: Accessibility
You can increase the reach of your Android app and make your app more user-friendly to all kinds of users by building it to take advantage of Android's accessibility features. This course will teach you how to do just that.
What you'll learn
Many users have physical limitations that may make seeing the device display or interacting with the touchscreen difficult. Android provides a number of accessibility features and services and this course, Android Fundamentals: Accessibility, will serve as your guide to including these features in your apps. You'll start with an introduction to the goals of accessibility and how Android handles accessibility. Then, you'll get started making apps accessible by incorporating support for non-touch navigation and view descriptions, as well as seeing how to design and create apps that provide a single high-quality experience that works equally well for users with or without accessibility needs. You'll also get to see how to add some important accessibility features, such as Talkback support and d-pad navigation, to your custom views. Finally, you will go over the important relationship between testing and accessibility. By the end of this course, you'll be better able to build apps in such a way that they will be accessible to all users.
