When users enable the TalkBack accessibility feature on their mobile devices, each single swipe across the screen moves the focus from one UI element to the next. (An alternative to single swiping is to explore UI elements by dragging a finger over the interface.) As a UI element comes into focus, TalkBack reads out the name of the element. If the user double-taps anywhere on the screen, the focused action is performed.

For guidance on enhancing the accessibility of your Android app, refer to the Android accessibility documentation. In particular, it's good practice to add an announcement describing the map. To specify the text of the announcement, call setContentDescription() on the view.
