Android Fragment Shared Elements not working with add

Question

I'm trying to make a transition animation with fragments, which I find strange (or maybe I don’t understand something correctly), is that when using replace it works as expected, but when using add it doesn't .. .

WORKS:

 EndFragment fragment = new EndFragment(); FragmentManager fragmentManager = getFragmentManager(); fragmentManager.beginTransaction() .addToBackStack(null) .addSharedElement(imageView, imageTransitionName) .addSharedElement(textView, textTransitionName) .replace(R.id.container, fragment) .commit(); 

DOES NOT WORK:

 EndFragment fragment = new EndFragment(); FragmentManager fragmentManager = getFragmentManager(); fragmentManager.beginTransaction() .addToBackStack(null) .addSharedElement(imageView, imageTransitionName) .addSharedElement(textView, textTransitionName) .add(R.id.container, fragment) .commit(); 

Any ideas?
