Hi, have a look in the download section. you'll find a zip file with the source.
i'm handling zooms by hooking into the onDraw-method und checking the current zoomLevel. if it changes, it will fire its on zoom event. to overcome the problem not having any feedback wenn the animation is finished, i added a 1 second delay before calling the lazyload-process (only in case of a zoom). the library ist not perfect and version 1, maybe you can contribute some improvements. i'll have time to work on it after the ADC...
