The implementation that is currently part of the rosjava stack is an older version that was written during the times of JNI rosjava. It has only quickly been ported to use the new rosjava. That being said, I've pointed a colleague who has been regularly using actionlib with rosjava to your post. I would suggest first trying the pubsub tutorial with your current network setup. If that works, you can be sure that the current actionlib implementation, and not rosjava, is to blame. > A short summary: I'm trying to establish a ROS connection between an Android > device and an Ubuntu in a virtual machine.

Is the combination “rosjava on android and roscore > on a virtual Ubuntu machine” possible at all? Has anybody tried that before? This is definitely possible.

They are compilable but won’t actually run). No. Most of the documentation for rosjava is in javadoc. We're working on updating the example projects to serve as tutorials and will eventually point existing wiki documentation to their respective javadoc replacements. > I hope someone out there can help me. > > greets, markus > > _______________________________________________ > ros-users mailing list > ros-users@code.ros.org > https://code.ros.org/mailman/listinfo/ros-users > -- ---------------------------------------------- Damon Kohler Software Engineer Google Germany GmbH Dienerstr. 12 80331 München ---------------------------------------------- AG Hamburg, HRB 86891 Sitz der Gesellschaft: Hamburg Geschäftsführer: John Herlihy, Graham Law, Lloyd Martin, Kent Walker ---------------------------------------------- Diese E-Mail ist vertraulich.
