In this project there are shown six micro applications that show how to implement accessibility functions both in a native way (with Android Studio in Java for Android and with Xcode in Swift for iOS) and in a cross-platform way using Xamarin in C#. The Accessibility functions that are shown in the micro apps are: - AccessibilityName: show how to specify attributes that contribute to form the text-to-announce - AccessibilitySpeech: show how to read a text with the screen-reader TTS - AccessibleView: show how to set a listener for accessibility events (e.g an interface object acquires or loses the focus) - ChangeFocus: show how to assign the accessibility focus to a user interface object - FocusOrder: show how to programmatically change the accessibility focus order - HideFocus: show how to specify wheter a user interface object shouldn't receive the accessibility focus
