Some of the class members are used in most of the examples, as
they provide standard functionality needed to perform SNAP Mobile
operations and display results:
•
Console console
: a utility console to display text information
being sent to or received from the server
•
int gameClassID
: the unique game ID in the game server that
identifies requests and responses as belonging to this game, so the
server knows where to send packets requested by the game; a game
