[GraphHopper] Call load error

[Peter]

Hi Daniele,

hmmh, sounds more like a bug with some special circumstances with your
device. Maybe it cannot access some files or disc was full etc?

Would you check in saveDoInBackground what the result of
new File(mapsFolder, currentArea).getAbsolutePath()
is and what
tmpHopp.load(new File(mapsFolder, currentArea).getAbsolutePath());
returns?

Regards,
Peter.
