ProgressWheel is not updating on orientation change

[farhan]

I am using ProgressWheel, custom view class in my project.
Its working fine in normal scenarion i.e. in 1 mode (either portrait or landscape)
but when I change the orientation its stops updating the progress of view and the root cause is, it stop calling onDraw() function when you call invalidate() on postInvalidate().
