Use reflection for getView, getSettings, getTextSize/getTextZoom, and
setTextSize/setTextZoom so that the View does not need to be cast as an
android.webkit.WebView.
TalkBack announces successive AccessibilityEvent.TYPE_ANNOUNCEMENT
events by adding rather than flushing the queue.
With Android’s migration away from using ChromeVox for WebViews, this
became more noticeable.
Adding AccessibilityManager.interrupt() before the announcement stops
any speech that may be in progress, before making an announcement.
Adjust behavior of MobileAccessibility.updateTextZoom and
MobileAccessibility.getTextZoom so they both return the correct updated
zoom value to a callback method.
Adjust behavior of isTalkBackRunning and isVoiceOverRunning so that
they return true only for the appropriate platform.
More robust iOS support is forthcoming, but currently works with iOS7
Dynamic Type Fonts by setting the following css on the body and using
relatively sized fonts sizing for child containers, for example:
body {
font: -apple-system-body;
}
body > .app {
font-family: 'HelveticaNeue-Light', 'HelveticaNeue', Helvetica,
Arial, sans-serif;
font-size:0.75em;
font-weight: 200;
}
The WebView typically injects AndroidVox from a Google server when it
launches a page with TalkBack enabled, however, in the unlikely event
that the app launches without a network connection and AndroidVox has
not been cached from an previous connected session, AndroidVox will not
start and the app will be inaccessible. We try to mitigate this by
injecting AndroidVox from a local path.
Correct MobileAccessibility.stop() method on iOS, postNotification
requires a string as the second parameter, but we should allow a
notification without a string.
Simplify naming convention for accessibility status events.
closedcaptioningstatusdidchange -> closedcaptioningstatuschanged
guidedaccessstatusdidchange -> guidedaccessstatuschanged
invertcolorsstatusdidchange -> invertcolorsstatuschanged
monoaudiostatusdidchange -> monoaudiostatuschanged
MobileAccessibility.postNotification now allows you to send
UIAccessibilityScreenChangedNotification,
UIAccessibilityLayoutChangedNotification, and
UIAccessibilityPageScrolledNotification in addition to
UIAccessibilityAnnouncementNotification.
Refactor isVoiceOverRunning and “voiceoverstatuschanged” to the more
platform agnostic isScreenReaderRunning and “screenreaderstatuschanged”
in anticipation of Android support.
