In google maps for android we have the possibilty, to load and manipulate the bitmaps, that are used for markers. In google maps for bj4, we use files in assets folder to set the markers. I want try to manipulate the markers to give the users a bit more information, so 5 different colors could show, how much earning each customer has. We also have code, to bring letters to bitmaps, so that we can make an index table in gmap. Is it possible with the gmap java object, to manipulate the loaded bitmaps, after a marker is set?
