Comment changer l'icône du marqueur Google Maps?

Question

Je souhaite modifier l'icône de marqueur sélectionnée sur Google Maps, j'ai donc le code suivant:

googleMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
        @Override
        public boolean onMarkerClick(Marker marker) {
            if (null != currentMarker) {
                currentMarker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.ic_arrowautougasen));
            }
            currentMarker = marker;
            currentMarker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.ic_autoselektovan));              
            return true;
        }
    });

 googleMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {
        @Override
        public void onMapClick(LatLng latLng) {
            if(null != currentMarker) {
                currentMarker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.ic_arrowautougasen));
            }
            currentMarker = null;
        }
    });

Sur cette ligne, j'obtiens une erreur ci-dessous:

       if(null != currentMarker) {
                currentMarker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.ic_arrowautougasen));
            }

Voici comment définir un drawable comme marker sur Google Maps:

    mMap = googleMap;

    BitmapDescriptor icon = BitmapDescriptorFactory.fromResource(R.drawable.your_drawable_here);
    LatLng sydney = new LatLng(-33.852, 151.211);
    MarkerOptions markerOptions = new MarkerOptions().position(sydney)
            .title("Marker in Sydney")
            .snippet("snippet snippet snippet snippet snippet...")
            .icon(icon);
    mMap.addMarker(markerOptions);
