Actually i need a list of coordinates on which the line is drawn mention in the picture in details
When drawing a PloyLine
save it in a global variable , If there are multiple PolyLines
save them in a list . Use method polyline.getPoints()
on PolyLine
variable it will give you the List<LatLng>
Edit: If you want multiple points just find the center point between two points check midpoint between two latitude and longitude
