[GraphHopper] Minimal setup for Android?

[Peter]

Trying GraphHopper with Android Studio is still on my todo list but why
not use gradle config and just add GraphHopper as dependency there? No
need to mess around with JARs etc

See the Android docs. No need to store the pbf files on the phone. And
yes you can put the graphhopper files and the map files in the apk
