You could use something like this:
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("http://maps.google.com/maps?saddr=20.344,34.34&daddr=20.5666,45.345";));
startActivity(intent);
You can use an actual street address instead of latitude and longitude.
However this will give the user a dialog to choose between opening it via
browser or Google Maps.
If you are in the US, you could use an unofficial way (Since it isn't
official, I don't recommend using it). This will fire up Google Maps in
navigation mode. Haven't played with it since where I live it isn't
available.
Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("google.navigation:q=an+address+city");
If you want to get rid of the dialog you can give the intent a hint as to
which package you want to use.
Before the startActivity() add this:
intent.setClassName("com.google.android.apps.maps",
"com.google.android.maps.MapsActivity");
