Google Code-in

This task is to go through our code and replace any deprecated methods with their non-deprecated counterparts, as long as the replacement doesn't require any additional code.

For example, instances of supportInvalidateOptionsMenu() can be replaced with invalidateOptionsMenu() with absolutely no further changes.

To get this task finished, find at least 3 deprecated methods which can be replaced by their counterparts without changing any more code (or less, if there's really nothing left :)).
