Ghraphhopper has a SDK navigation to integrate with applications.
So, I downoaded the sample code following this tutorial instructions https://www.graphhopper.com/blog/2019/02/11/get-started-with-graphhopper-navigation/
In this tutorial says that you change [YOUR_KEY] (in developer-config.xml) and junst replace by your graphopper key. So I login in my account an in the API keys, just copy one key and put in the code.
When starts the application, the map show nothing (just a white screen). When I debug code the onMapReady event not fire.
I’ve made more test, for example if put this addrees (that stay in developer-config.xml) in my browser: https://tiles.mapilion.com/assets/osm-bright/style.json?key=<> just answered: Unauthorized: Invalid key. Please contact us and retrieve a valid key.
What’s the correct graphopper key? just the API key section on my profile?
