Android orientation quesiton

[Sam]

I am trying to understand more about the orientation in Android.

However, when I trace to WindowOrientationlistener.java

the following configuration confuses me.

// The minimum amount of time that must have elapsed since the device stopped
// swinging (time since device appeared to be in the process of being put down
// or put away into a pocket) before the proposed rotation can change.
private static final long PROPOSAL_MIN_TIME_SINCE_SWING_ENDED_NANOS =
NANOS_PER_MS * 300;



Well, from what it's been defined,

I assume if I keep swinging the device and then suddenly stop, the device
will wait 300 ms to do the rotation.

However, when I changed the value to 3000ms (which is 3 secs), I expect the
device will wait 3 secs to do the rotation but the orientation changed in 1
sec.

Did I misunderstand the meaning of this constant? how to do the test for
this?

Thanks
