Android and draw routes in Google maps

Question

I have a small problem, I need to develop an application that shows the route of public transport, I found tutorials about route of cars.

I saw this example: http://maps.google.com/maps?f=d&hl=en&saddr=25.04202,121.534761&daddr=25.05202,121.554761&ie=UTF8&0&om=0&output=kml

and tried to add dirflg = & rB the URL to show the public transport but server responded with the empty kml.

Does anyone know how to help me?

Answer 1

assuming that you are asking this for android, you can use the following intent

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);

where saddr and daddr are starting and destination address's location coordinates.

same has been discussed in several threads already
