but not removing map ?please help

you adding same marker twice:

                endpointmarker = mmap.addmarker(new markeroptions()                         .position(new latlng(lat, lng))                         .title("location").snippet("" + address));                  markers.add(mmap.addmarker(new markeroptions()                         .position(new latlng(lat, lng))                         .title("location").snippet("" + address))); 

just remove 1 call googlemap.addmarker.
