Question

I need to add custom markers to a mapview.
First question : is there a standard/default overlay/marker that I can use ?
Second : if I’ve to create a png for the marker overlay, which is the best size for the image ? Do I have to create different images for each screen sizes (ldpi, mdpi, hdpi) ?

Answer 1

1. Extend ItemizedOverlay and use OverlayItem, where you can set you custom drawable via setMarker(drawable).
2. Depends on your design. I personally used 32×32. You should give different sizes a try an see how they fit.
3. Yes, this is preferable. You can use bitmap drawable, which can automatically resolve based on your screen size.
