16. Solution: Calendar Provider

Solution Explanation

Correct Answer: resolver.update(CalendarContract.Calendars.CONTENT_URI, values, null, null);

resolver.update(CalendarContract.Calendars.CONTENT_URI, values, null, null); 

Is the statement you would use. Since you want to change pre-existing information, you use update. Then you specify what you want to update by using CalendarContract.Calendars.CONTENT_URI as the first argument. Next you pass in the variable values, which defines what content to change. Note that CalendarContract is a Contract class that stores data associated with the CalendarProvider.
