Question

The new Shared Element Transitions works when i use Fragment \'replace\' but i can\'t seem to make it work fragment \'add\'. I use the same container in bo

Answer 1

I guess it is because the new fragment is placed on top of the old fragment. The old fragment is not being placed out of the controller and onPause (and sequenced methods) aren't being called. It doesn't play any transitions because the old fragment might still be visible to the user (the system doesn't know that).

In my answer (where you commented) I added an enter and exit transition. If you add it, does it even animate? If not, it's probably because of the stated reason.
