Currently none of the icon button has accessibility texts. VoiceOver will read the file name of the icon image when the focus is on the icon button, e.g. it says "ic_refresh" and "ic_menu" instead of localized string "Refresh" and "Menu".
Currently none of the UI element has accessibility label. We will need to add accessibility texts for icon buttons, text fields, and other UI elements.
