[android-developers] On Tap event Maps

Hi!

I'm using a OnTap method, and I want to draw over Gmaps the route from where am I, to the point I'm pressing, after seeing all the points on the map.

Everything works perfectly, I have the location, I have the destination, but I dont know how to pass latitud and longitud, from the principal file.

protected boolean onBalloonTap(int i, OverlayItem item) {

Toast.makeText(c, "Calculando ruta... " ,Toast.LENGTH_LONG).show();

double latitudo = 43.250064;

double longitudo = -5.774496;

double latitudd = 43.223914;

double longitudd = -5.781582; 

String uri = "http://maps.google.com/maps?saddr="+latitudo+","+longitudo+"&daddr="+latitudd+","+longitudd+"&mode=walking";

Intent intent = new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(uri));

intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");

c.startActivity(intent);

return true;

}

How can I pass from the principal file the value for latitudd, longitudd... Is it possible with one kind of bundle? 

Thanks for the answers!

Artemio
