My question is simple, I wonder if I could use nutiteq API in my android app with a free licence membership key (which is required to render MapView), download map tiles from other free wms sources (such as OSM) and still be able to use the API for commercial purposes for free? I came down to the following link when searching for an answer to my question: https://github.com/nutiteq/hellomap3d/wiki/Free-openstreetmap-license
If not possible, what would be another alternative for 3d map rendering API/Library to be used for both commercial and personal cases in android?
For Nutiteq you would need enterprise license for this kind of commercial uses. We have invested years of our effort developing it, so asking everything for free sounds quite weird from a software developer who does provides commercial projects. What about free Google Maps?
