use of android.view.accessibility.AccessibilityEvent in project SunDay by iQuick.

the class Manager method announceForAccessibilityCompat.

/**
 * Generates and dispatches an SDK-specific spoken announcement.
 * <p>
 * For backwards compatibility, we're constructing an event from scratch
 * using the appropriate event type. If your application only targets SDK
 * 16+, you can just call View.announceForAccessibility(CharSequence).
 * </p>
 * <p/>
 * note: AccessibilityManager is only available from API lvl 4.
 * <p/>
 * Adapted from https://http://eyes-free.googlecode.com/files/
 * accessibility_codelab_demos_v2_src.zip via
 * https://github.com/coreform/android-formidable-validation
 *
 * @param context Used to get {@link android.view.accessibility.AccessibilityManager}
 * @param text The text to announce.
