Fixed cancel() not working correctly

The method handleMessage(Message msg) from mHandler variable was
not checking if the timer was cancelled, so
sendMessageDelayed(obtainMessage(MSG), delay) was keeping the
timer alive. The patch simply adds a boolean and checks if the
CountDownTimer was cancelled before calling
sendMessageDelayed(obtainMessage(MSG), delay)

Fix the issue that the top of fullscreen dialog is clipped away

The visibility of status bar comes from the top fullscreen window,
not from the focused window.
That has to be taken into account during the calculation of the
decor rect. You can use mTopIsFullscreen for this purpose.
