The android_core stack is evolving toward something like rviz.
However, rather than focusing on a single rviz-like application, the
focus is on creating Android Views that could be combined to build it.

One example is the  VisualizationView:

I think re-implementing everything with Android in mind is the best
approach. Attempting a direct port will probably lead to
inflexibility and sub-optimal performance.

There are a lot of additional considerations when working on mobile
devices that, as a desktop application, rviz does not need to take
into account.

I've been focusing primarily on mapping, other point-like
visualizations, and 2D camera control for now. Once the views are in
place, building a flexible app, like rviz, that can be configured at
run time to show arbitrary topic data should be straight forward.
