Re: [android-developers] Action mask

Quoting from http://android-developers.blogspot.com/2010/06/making-sense-of-multitouch.html:

"The ACTION_POINTER_DOWN and ACTION_POINTER_UP events encode extra
information in the action value. ANDing it with
MotionEvent.ACTION_MASK gives us the action constant while ANDing it
with ACTION_POINTER_INDEX_MASK gives us the index of the pointer that
went up or down."
