Android - Remove the straight line while displaying multiple routes on a map -
in application, display of map , multiple routes between source , destination done using google mapv2 api. problem is, while displaying multiple routes on map, 1 straight comes along correct routes. want rid of straight line between source , destination. trying find way past 2 days. please guide me.
displaymap.java

fallow how draw free hand polygon in google map v2 in android?
there's deep discussion same on there ...
kindly check out list part how things happened on there.
your logic can check source , destination point regularly. after need create common method draw path on map.
