I've been struggling to figure out the best way to build a gps inside of my app. I was wondering which TomTom api's I need to use, in order to have real time routing as a person's car moves forward, on a map, and the directions are displayed as the car moves. I would need the route to adjust and move as the car moves. Would it just be a combination of routing, and the maps sdk? Also, can this kind of feature be done in a react native web view for a mobile app, or do I need to build it in android/java in a native module. I would really appreciate any help.
