[GraphHopper] Generating routing files

[Menion Asamm]

Thanks guys,

I'm building it on PC not in device. What I want is pre-prepared packs 
for every country.

I use default /config.properties/ file and only change 
'osmreader.acceptWay' parameter. Anyway now during testing I found, that 
files generated with

prepare.chShortcuts=no
osmreader.acceptWay=car

create a smaller pack for car (just around 60 MB) - it's OK, but this 
file throws same issue as I wrote before

/    java.lang.IllegalStateException: Cannot load the graph when using 
instance of com.graphhopper.storage.LevelGraphStorage and location: 
/storage/emulated/0/Locus/mapsVector/czech-republic-latest.osm-gh///
//            at 
com.graphhopper.storage.GraphHopperStorage.loadNodesHeader(GraphHopperStorage.java:1456)//
//            at 
com.graphhopper.storage.GraphHopperStorage.loadExisting(GraphHopperStorage.java:1408)//
//            at com.graphhopper.GraphHopper.load(GraphHopper.java:743)/

I've tried to change parameter 'setCHShortcuts' in my app, but no result.

/            GraphHopper tmpHopp = new GraphHopper().forMobile();//
//            tmpHopp.setCHShortcuts("no");/

Understand understand. I just because of second limitations, best should 
be to create as big files as possible. Anyway I'll try it.
