Older devices had a pretty small limit for maximum bitmap sizes, so you are probably running into that (as you zoom in really far, the image gets too large and an error occurs in the Android graphics framework). That would still be an issue even with tile-based rendering (at least for the approach I want to use). This is not a problem on newer devices though, as the maximum bitmap size is something like 4096x4096.
