[GraphHopper] Problem with the type of te path (Car, pedestrians, bike)

[Peter K]

Hi Bruno,

some things to clarify:

 * if you need CH you need the preparation step (your graph size will
double roughly) and you are tight to only one vehicle
 * Now, if you setup GraphHopper on Android to use FOOT (and CH) you
have to use FOOT for the preparation step which you do on your desktop
computer
 * if you don't need CH you could import all vehicles and query what you
like

> GraphHopper tmpHopp = new GraphHopper().forMobile();

That is just a convenience method. Have a look at the source to get
better understanding of it.

Graph: car:com.graphhopper.routing.util.CarFlagEncoder"


You are trying to load an already imported graph (where only car was
imported) with configuration 'foot'. Just drop the graphhopper folder on
disc and re-run the import procedure for the new config.

Regards,
Peter.
