How to remove a specific marker?

Answer 1

Thank you, I figured it out myself.

final Marker asd = mMap.addMarker(new MarkerOptions()
                .position(new LatLng(0, 0))
                .flat(true)
                .title(String.format("123")));

        mMap.setOnMyLocationChangeListener(new GoogleMap.OnMyLocationChangeListener() {
            @Override
            public void onMyLocationChange(Location location) {
                
                LatLng ttt = new LatLng(location.getLatitude(), location.getLongitude());
                asd.setPosition(ttt);
            }
