MotionEvent

getAction() returns a pointer id and an event (i.e., up, down, move) information.

getActionMasked() returns just an event (i.e., up, down, move) information. Other info is masked out.

For example:

getAction() returns 0x0105.
getActionMasked() will return 0x0005, which is 0x0105 && ACTION_MASK.
