Fragment Is Not Showing

The problem is a bit weird and complex - sometimes (it is not deterministic or I do not know the cause) some of my fragments are not showing up in transaction. I checked everything

Solution 1:

OK, it's wonderful how often you come up with a solution while showing your problem to the others - the problem here was in hide / show animations - there was a use case when I was hiding a fragment with some kind of animation (scale to 0.0, fade, etc.) and later (special case) show it without an enter reverse animation (as an optimization) - fragment WAS shown, but remain scaled to 0 or faded.
