[GraphHopper] Version incompatibility

[Jaak Laineste (Nutiteq)]

Hi,

I also suspect that you somehow used 0.2 version graphhopper to generate graphs.

With a little effort you can also try to use different (newer or older) graphhopper JAR versions with Nutiteq SDK, as long as you use also graphs with corresponding version. To change it I would do following:
1) change graphhopper version in pom.xml 
2) change GraphhopperRouteActivity.java [1] (from where you probably got GH-Nutiteq integration code) to reflect GH API changes. With all updates there have been mandatory small GH API changes - some parameter renamed, some added, some removed. It should not be more than 1-2 line changes, as client uses just one API call, but Peter knows best. Maybe there is even update guide somewhere in release notes?

In a production app I would use the latest Graphhopper version (0.4?), for both data processing and in mobile. Nutiteq SDK sample app may have older version. Pull requests are welcome :)
