- Clear the event of onVisibilityChange when any option is clicked.
- Redirect visibilityChange of Settings to System app. System app handles the event is a better strategy.
- Add test case to handle on visibility change event from Settings app.
The parameter "message" in addCloseNotificationsEvents will be used in onVisibilityChange.
It still needs to allocate a variable to store the binded function if it uses "bind" to add event listener.
So an extra variable is necessary. Thank you.
