[GraphHopper] Offline navigation using Graphhopper

[Awais Bin Asif]

Hello Peter

First of all thanks you very much for developing such a good API. It is
really amazing.

I am developing an Android app. Which plan route according to local
transportation  available in city and it plan route for shortest path for
which i used graphhopper and it really helped me alot.

Now i want to add feature of *offline navigation*. And it should give
directions in written form like google provides. I think i can get these
directions from GeoPoints i get after applying dijistra algo. But i don't
know how to detect turns from GeoPoints. Can you please tell me is there
any help available in Graphhopper??? or some alternative.
