[zeromq-dev] Android UnsatisfiedLinkError

[Will Heger]

Thank you for the fast response Victor.   I saw something similar to this
in an ffmpeg ndk linking problem, so yes, I will fiddle with it and report
back my findings.

I'm in over my head with ndk, so if I'm unsuccessful I'll probably try to
switch to the all Java (jeromq) version that was just posted and report how
that goes for anyone who might want to skip the shared object.

Best regards,
-Will
