Hi! i develope tizen 2.2.1

i try the accurate moment about rotation end or start.

when i see IDE example source. many source check use Tizen::Base::Runtime:Itimerevent for check animation end moment or start moment

but OnExpiredTimer func is has some problem of my source.

i want callback fucntion of animation. 

is it exist callback fucntion of animation start moment or end moment????

Thank you!
