What maps to choose for GIS-Android application?

Question

Android

Hello, dear visitors of habr!
In the near future I will participate in the development of a GIS application for android.
Accordingly, the question arose - which cards to use?
The application will be commercial, which imposes some restrictions, as far as I understand.
Has anyone had experience with this kind of development? Who used which cards? Which API maps are nicer? What are the pros/cons of the different cards?

Answer 1

OSM, of course. The license is very liberal, it can also be used in commercial projects, which many people do. If desired, you can show the user not standard tiles, but independently rendered ones, with a custom view and data set.
You can generally take bare vector data and do whatever you want with it. Routing, pulling out POIs by category, address search, counting and monitoring various parameters ... Gis-lab.info to the rescue.

Answer 2

Choose a map from Google, it's free rebuffs until the time
