Kostya,

do you mean that in onDoubleTap (MotionEvent e) listener I should
modify "e" by:

e.setAction(MotionEvent.ACTION_CANCEL)

and then "feed" gesture detector with that modified event?

but if it cancels internal state of detector why to use a Handler?

btw I already tried in onDoubleTap to post Runnable that starts
activity and it worked well but I decided it's dirty workaround -
that's why I used onDoubleTapEvent
