Please provide some idea,

I am trying to decrease the polyline in google map as the marker moves towards the destination.

under you onChangeLocation.

after requesting for new location. clear the map then create a polyline from your current location to your destination. everytime you request for new location and you move towards your destination the polyline become shorter and shorter.
