Hi Rmac,
I believe there are some dependencies that the library has that work
slightly differently in Android, so just dropping the JAR file into
Android won't work. However, I believe the Android folks are aware of
this and working to figure out a way to have the client library work
on their platform.
You might want to try asking in their developer forum:

Cheers,
