Browsing will only inform you about services that are available, are
coming or are going.

Resolving will inform you about all the meta data of a service, i.e.
everything that goes beyond a mere name: address, port, host, TXT data. 

Usually resolving is a one-shot operation: if a user chose one of the
items from the service list you just resolve it and connect to it, and
the close the resolver again.

However in some situations (like yours apparently) it makes sense to get
notifications about meta data changes (i.e. addres, port, host, TXT data
changes). For these cases you can keep the resolver open. It will then
notify you each time the meta data changes (by raising another
AVAHI_RESOLVER_FOUND) or if this specific service goes away

Long story short: just keep your resolver open and what for more
