[osmosis-dev] Android?

[Adrià Ribatallada Torelló]

Thank you Brett, I'v followed your advice and tried to remove the JPF from
a local clone of the osmosis source, and adapted the plugin I need to use
the osmosis-plugins.conf.

And all compiles good and fine, and if I execute the command I need using
the bin/osmosis script in my machine all goes fine.

But in the Android device I need to do it from the code (or so I think),
calling Osmosis.run(args) or Osmosis.main() I presume, and there is where
it fails now...

That's the code I'm trying to run:

        File pbfFile = new
File(Environment.getExternalStorageDirectory()+"/download/"+"in.osm.pbf");
File outFile = new
File(Environment.getExternalStorageDirectory()+"/download/"+"out.map");

Osmosis.main(new String[] {
"--read-pbf file="+pbfFile,
"--mapfile-writer file="+outFile
});

That's my pretty error:

org.openstreetmap.osmosis.core.Osmosis run

org.openstreetmap.osmosis.core.OsmosisRuntimeException: Task type read-pbf
file=/mnt/sdcard/download/in.osm.pbf doesn't exist.

I assume that is thrown because the envirenoment it's not well configured,
but I don't know how to "do the same" that does the script from my program
code :P

I'v tried to run the classworlds.Launcher, but I didn't suceed there...

Can some of you help me understand what needs to be done "programatically"
to setup the environment?

Thanks again.
