I need to display around 30 markers in a somewhat small area.
Is there a way to resize Google Maps API V2 markers when the user changes the zoom?
Or should I jus
There is no an outOfTheBox option to change the icons for the markers. you will have to listen to zoom changes:
outOfTheBox
How to listen for user generated zoom in Google Maps?
and to remove the older markers and set new ones in their location with smaller icon images.
