Does android_tutorial_pubsub connect to other ROS Masters?

edit

I've built and installed android_tutorial_pubsub from source, but it doesn't seem to connect to a specified ros master on a host computer. I'm running it on an Asus Transformer Prime with Ice Cream Sandwich (4.0.3). Should I expect this to work in this way?

I've also tried it on a Honeycomb tablet (Iconia Tab) and a Gingerbread Nexus One (2.3.6) all with the same behavior, so I'm assuming I'm missing something.
