Android fragment transition: call postponeEnterTransition() only when necessary

Question

I am studying to use fragment transitions, and the basic sample works fine for me.

My request is simple, I have a pager fragment, which is the destination of many other navigation fragments.

So I want to do postponeEnterTransition() and startPostponedEnterTransition() ONLY when it is necessary.

Because I will only enable the fancy transition in some of the originator fragments, not in all of them.

Is there some method like "isEnterTransitionAvailable()"?

Thanks a lot.
