How do I launch Google Maps from my own application to show road directions from current position (GPS) to a specified address?

    Do you want to use the Maps from Google Maps or do you really want to launch Google Maps on your Mobile device and quit your application? – bastianwegge Apr 21 '11 at 06:56

  • I want to launch google maps (and quit my app). I could still use the back button to get back to my app, right? – jgauffin Apr 21 '11 at 07:06

This intent should launch the appropriate Maps Activity with the directions input screen populated with current location and a destination point:

Intent intent = new Intent(Intent.ACTION_VIEW, 
    Uri.parse("http://maps.google.com/maps?f=d&daddr=51.448,-0.972"));
intent.setComponent(new ComponentName("com.google.android.apps.maps", 
    "com.google.android.maps.MapsActivity"));
startActivity(intent);

  • Jeff, I was wondering if the parser would handle the `&output=kml` parameter? I'm interested in displaying a route with some placemarks that's actually published online as a public map. – Nano Taboada Feb 03 '12 at 18:25

Uri uri = Uri.parse("geo:40.763500,-73.979305");
Intent intent = new Intent(Intent.ACTION_VIEW, uri);
startActivity(intent);

Try it.

For more information:

// Map point based on address

Uri location = Uri.parse("geo:0,0?q=1600+Amphitheatre+Parkway,+Mountain+View,+California");
Intent mapIntent = new Intent(Intent.ACTION_VIEW, location);

// Or map point based on latitude/longitude like the answer of @wegginho

Uri location = Uri.parse("geo:37.422219,-122.08364?z=14"); // z param is zoom level
