I have list of marker in my map. When I clicked any marker it draw a route between that marker with my current location. My problem is when I click another marker previous route polyline remains in map. I want to remove it. Note : Not to use GoogleMap.clear() because when GoogleMap get cleared list of marker also get cleared
Thanks in advance
