[GraphHopper] GraphHopper Digest, Vol 2, Issue 3

Mon Apr 8 10:59:57 UTC 2013

Hi Peter, thanks fr your answer ,

> Change the line "#osmreader.chShortcuts=fastest|shortest" to
"osmreader.chShortcuts=fastest" in the file

i do that because because if I don't do this I get a message that tells me
to use the class LevelGraphStorage when I saw the code of OSMReader.java I
found it necessary to activate the class osmreader.chShortcuts in order to
use LevelGraphStorage instead of GraphStorage, otherwise I have no interest
to make this adjustment.

I dont need a desktop version but i need an offline version for android. I
tested the android app & the graph is loaded normally, but the  roads given
are wrong, when i saw the osm file i noticed that the ways with the
attribute highway="residential" for example aren't taken into consideration
by the routing process. Is there a way to fix that??

When i tested the master version with UI , i saw that the routes are
correct !, and all ways are taken into consideration, i need the same
result on the android app.  Thanks in advance for your support
