Hi,
I am working on a prototype port of one of our iPhone apps to Android.
The iPhone app uses the RouteMe API to load our own custom maps into the application. (also tiled, just like Google Maps itself, so only loading what you see at that moment - this is very important in this case)
I have been searching for a similar product for Android. I found Nutiteq, but as RouteMe is free, I am trying to find something free for Android as well.
If anybody has suggestions, I would love to hear them. The more information the better, of course :).
EDIT: Still haven't found anything that acts the same as RouteMe, so suggestions are still very welcome.
