Good news! I upgraded my device to cupcake, and it appears that I can now receive onSensorChanged events when the screen is off, provided that I hold a Partial Wake Lock.
However, the sampling frequency seems to be far more sporadic. I think that it has to do with the fact that cupcake now flips the orientation of all applications, and when it does the redrawing, it suspends the application (and thus the sensor listeners). I'm experimenting with turning this auto-orientation behaviour off (Anyone know how to do this on an application-by-application basis, rather than turning it off in the device settings?). Anyway, things look good for those of us who wanted sensor data without having to leave the screen on. Jordan On Apr 20, 10:55 am, Jordan Frank <[email protected]> wrote: > Known but not resolved.
