Launching Google Maps Directions via an intent on Android

Question

My app needs to show Google Maps directions from A to B, but I don\'t want to put the Google Maps into my application - instead, I want to launch it using an Intent. Is this

Answer 1

if you know point A, point B (and whatever features or tracks in between) you can use a KML file along with your intent.

String kmlWebAddress = "http://www.afischer-online.de/sos/AFTrack/tracks/e1/01.24.Soltau2Wietzendorf.kml";
String uri = String.format(Locale.ENGLISH, "geo:0,0?q=%s",kmlWebAddress);
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
startActivity(intent);

NOTE: this example uses a sample file that (as of mar13) is still online. if it has gone offline, find a kml file online and change your url
