I'm working on a custom view for an android application, similar to the Analog Gauge sample code available from Mind the Robot.
Running the code from listed site, I get see this on my screen:
(Motorola Droid, 2.2.3), (Emulator, 4.0.3)

(Xoom, 4.0.3)(Other phone, 4.0.3)

The hand is missing!
The drawing calls are being made (I can see them in logcat), but the canvas elements the calls draw are invisible.
It's not API level dependent, though; if I import it the right way into a project, it will hand will show up when I run it on the Xoom.
But, when I move the files to a different project folder (same source code, same layouts) it goes back to missing the dial.
What's going on? How could the same code be producing such different outcomes on different devices?
