Android google maps huge lag when adding colored markers

I noticed a huge amount of lag when adding some (50) colored markers onto a google map. There are about 20 different hue colors the markers need to have. I tried storing the generated BitmapDescriptor in a hashmap and from a background thread and retrieving it when adding the marker, which decreased the lag by about 10%. When I set no marker color and leave it on the default red, I get no lag at all.

How I add the markers:

googleMap.addMarker(new MarkerOptions()
                    .title(title)
                    .snippet(snippet)
                    .position(new LatLng(lat, lng))
                    .icon(BitmapDescriptorFactory.defaultMarker(hue)));

Is there anything I can do to prevent some of this lag, except using clustering, which will not work for me in this case.

This is a known issu, see #7174 for more informations.

To avoid this problem, you can use this directly (all the markers will be red in this case):

BitmapDescriptorFactory.defaultMarker()

Or the easiest way, use a custom markers :

BitmapDescriptorFactory.fromResource(R.drawable.custom_marker)
