This posting J2ME/Android/BlackBerry - driving directions, route between two locations suggests:

you must not use the Map Service with any applications for route guidance, including but not limited to turn-by-turn route guidance that is synchronized to the position of a user's sensor-enabled device

As such, there is no Android or Google API for showing the route between two points on Android, as far as I know. People have hacked it in by various approaches, but you run the risk of having your Map key disabled.

If I am wrong, I would love to be corrected.
