If you just have a source and destination, you can get the Maps app to
show its own route between them with something like this:
Uri uri = Uri.parse("http://maps.google.com/maps?
saddr=42.35892,-71.05781&daddr=40.756054,-73.986951");
Intent intent = new Intent(android.content.Intent.ACTION_VIEW, uri);
startActivity(intent);
That pops up a dialog asking the user if they want to complete the
action with the Browser or Maps app, though. You can start the Maps
app directly with a geo URI intent, but that only seems to support a
single location or query. I tried sending it a from/to query that
worked against the browser version of maps once, but that didn't work.
Too bad we don't have a more powerful way to start the Maps app. Would
be great if there were a way to send areas, multiple locations,
relative locations, etc.. Then you could ask it to show a square mile
one mile to the East, all gas stations 1 mile ahead, a map showing how
5 different locations are positioned w.r.t. each other...

I don't know any public equivalent to the com.google.googlenav
classes, or the com.google.android.location.GmmGeocoder class for
business searches, either. The official API doesn't seem to support
anything near as powerful:
http://code.google.com/android/add-ons/google-apis/reference/index.html
I'm stuck calling the web API and parsing the results to replace those
lately, myself.
Looks like some other devs are trying to replace Google Maps
completely:
http://code.google.com/p/osmdroid/
Or trying to talk to an embedded web version with JavaScript:
http://code.google.com/p/map-for-osp/
I'll have to look into those options for my own maps related apps
next, I guess.
