javascript - Google Direction | same API, different result -
i have simple route made on javascript on following link:
http://debug.iott.co.il/map/route.v.1.0.html 
edit here image javascript lazy ones.
it's goes b, b c , c d. watch this, when user hit point c need u-turn point d, fine me.
i have tried duplicate same thing on android studio, , i'm getting different route following image:
so instead of doing u-turn c d, it's makes user goto way again, b , lastly d. i'm trying figure out why i'm using same api (google direction) same configuration (driving mode etc.) , i'm getting different results. ideas ?
edit 2: here of code: javascript :
//you can calculate directions (using variety of methods of transportation) using directionsservice object. var directionsservice = new google.maps.directionsservice(); //define variable map points. var _mappoints = new array(); //define directionsrenderer variable. var _directionsrenderer = ''; //this give map zoom value. var zoom_option = 6; //legpoints route points between 2 locations. var legpoints = new array(); var currentpoi = 0;
