I want to write a navigation based Open Source realtime carpooling app. For this, I am evaluating the Graphhopper Server and the Graphhopper Navigation Example app as a base. I need open source software on both sides.
Now, the example app calls the Graphhopper Directions API, which is not open source, as far as I know. On the other hand, this page suggests, that both parts are open source and the README of the Navigation SDK says, that it plays well
with the open source GraphHopper server as well as the GraphHopper Directions API.
So what changes are needed, such that the app uses my own instance of the GraphHopper server instead of the Directions API?
Maybe I need only change the base_url in developer-config.xml and I just couldn’t figure out the path.
