[GraphHopper] custom flagencoder

[Peter]

Hi Fred,

please avoid duplicate postings

Regarding your problem: you have to use the same settings for the import
too.
So do the import with your custom flagencoder e.g. via tmpHopp.importOrLoad
deploy the created files to android and it'll work.

Regards,
Peter
