Does the Android version of processing.core.PApplet have a working .registerPre()?

I'm trying to get a sketch working on the emulator (and a device) using ArcBall, at:
(in fact, the sketch is a lightly modified version of the demo.)
Regular compilation of the sketch works, but when I switch to Android mode I get this error from the emulator:

Looking at the ArcBall.java file, I see that there is indeed a public pre() method.
Compiling without this library runs in the emu and on the device.
I can understand if this is just incomplete implementation at this point, but I want to make sure I'm not overlooking something else. (like the ArcBall code being 4 years old, and not compatible with the current version of Processing, which I feel is unlikely, given that it runs on the desktop.)
Thanks in advance for any insight!
