There is
LocationActivity
in VTM samples to check.
Animator has methods to move map center smoothly.
A location marker gets its coordinates from GPS, according to
sensor schedule, e.g. every ~1".

discussion in forum.
Can divide distance in steps to simulate smooth movement or use
more advanced solution like
Kalman filter.
BTW you probably mean VTM, please write library name in topic
title, for easy reference.
