Thank you for reply.
It was successfully complete. I was relieved. 🙂
Now, I think this issue should be fixed.
May be, runtime provides method like clearAnimation().
Because, game developers who using spine,
usually recycle spine animation instance.
Because loading spine animation is weighty task.
Default anmation -> setAnimation ->addAnimation -> end ->recycle instance init() -> setAnimation() ->......
Let me know, If there is another way.
