osmdroid rendering issue, zoom 16 rendering like 15

Question

I am rendering a map using osm droid(basic mode, I havent tweaked anything) and a map tile source rendered from Maperitive and bundled in a database where i am doing queries for the blobs. The problem is I have a friend developing an iOS app using the iOS Mapbox SDK with the same tiles and the issue is this: how come with the same tile source his app renders zoom level 16 correctly and osm droid renders zoom level 16 like zoom level 15. In fact, i have only experienced correct rendering on a crappy small density screen. Anyone who can shed some light on this matter, and if something can be done to fix this?

Answer 1

It sounds like you are experiencing Issue 523. The map tiles are not scaled to screen density in osmdroid. So when you are looking at zoom level 16 on your density=2.0 device (like a Nexus 10 for instance) it will look half the size as the iOS Mapbox which is probably scaling the tiles.
