[GraphHopper] [graphhopper android] Error with setting up development

[龚振华]

Thanks, Peter.

As to your suggestion, I built it all over again and get the .apk installed
on my cellphone.

But the map loading of japan.map still doesn't work. I've debugged it to
the code and guess it's the problem of using mapsforge. (I've built the web
component of your graphhopper as well and it works fine!)

So I raise it in the maspforge-dev group at Google, see
https://groups.google.com/forum/#!topic/mapsforge-dev/03ftndqcLM0.

Thanks for your consistant help and dedication, even for my stupid
questions. Really appreciate it.  :-)

Cheers,
