Google has the Directions API.

http://code.google.com/apis/maps/documentation/directions/

Just request the XML or JSON version and parse through it. I used this in the past to draw a Point to Point path over the Google Maps view. It worked fairly well and was fairly trivial.

Look at the XML output, http://code.google.com/apis/maps/documentation/directions/#XML

Although what I used was the Coordinate information, it should be fairly trivial to parse the html_instructions to do what you want to do.

Here is a link to a past discussion where you can find code that does part of what you want: How to draw a path on a map using kml file?

You want to look for the answer from Alvinsj, DirectionMapActivity class.

Enjoy!
