Route Map in Android: 

Uri uri = Uri.parse("http://maps.google.com/maps?&saddr=slat,slon&daddr=dlat,dlon"); 

Here saddr -> source address 
daddr -> destination address 
slat -> source latitude 
slon -> source longitude 
dlat -> destination latitude 
dlon -> destination longitude 
Intent intent = new Intent(Intent.ACTION_VIEW, uri); 
startActivity(intent);
