Thank you very much, Rud. I'm looking at your blog. One more thing I want to ask you. On your blog, you have a piece of code:
private class OrientationListner implements SensorEventListener { ... Currently, I'm still using SensorListener, and I think it's already deprecated. But when I changed it to SensorEventListener, my program didn't recognize it... it seems that I don't have this API.... But the thing is, the SDK i'm using is Android 1.5, which I think should include the API....So do you have any idea why this happens...? I looked at my android.hardware when I imported it. It showed that android.hardware only had the classes of Camera and SenorManager, and one interface of SensorListener... no SensorEventListener.. Also, getRotationMatrix is not recognized too... for which I already wrote another post to ask. I'm actually pretty new to Android, even Java...>_< Thanks, DD On Oct 5, 10:04 am, Rud <rudmerr...@gmail.com> wrote: > See my blog for code to do the > processing:http://mysticlakesoftware.blogspot.com/ > > Rud > > On Oct 4, 7:57 am, DD <daviddiaofri...@gmail.com> wrote: > > > > > Hi, > > > It seems that for onSensorChanged(), the orientation readings > > (yaw,pitch,roll) are not detected directly, but computed from the > > acceleration readings.
