I need to know is there is any way to pass two geo location to get driving direction.

Answer 1

yes its very easy to show the direction if you have the latitude and longitude of both source and destination. Just see the following code:

Intent intent = new Intent(android.content.Intent.ACTION_VIEW,
    Uri.parse("http://maps.google.com/maps?saddr="+latitude_source+","+longitude_source+"&daddr="+latitude_dest+","+longitude_dest));

    startActivity(intent);

Where latitude_source=Latitude of your source longitude_source=Longitude of your source latitude_dest=Latitude of your destination longitude_dest=Longitude of your destination

Just replace these value with your actual data. .Use the above code on some particular event.

Hope this will help you.
