Answer 1

I have faced the same issue, actually I used firebase and I have list of information and when user tap it will call detailActivity with sharedAnimation in this activity I was updating it as seen using firebase so firebase event updating the list item as seen, in this case this problem is invoking because recycler view that screen layout was getting effected.

and it invoke an exception because that transition id which one we have passed it was no more, so I solve this issue using this method.

onPause() I have frozen the layout and onResume() set it as false;

 @Override
public void onPause() {
    super.onPause();
    mRecycler.setLayoutFrozen(true);
}

@Override
public void onResume() {
    super.onResume();
    mRecycler.setLayoutFrozen(false);
}

And it's working.
