[android-developers] The accelerometer reading looks odd

[Yang Bo]

Hi，
I am trying to read the device accelerometer when the phone is placed
on a desk with screen up，I expect 0 on the x-axis and y-axis，-9.8 at
z-axis.  But I get
x:11，y:-37，z:-24(decimal part ignore)  What is this？  I read the doc of
accelerometer，  does not make it clear.  Could you please help :
1. Why x and y are non-zero？
2. Why the value is so large？

Thanks ！
