Transition to common Android elements up to 21

Question

How can I implement shared element transitions in pre-21 devices? I more or less followed the manual here http://antonioleiva.com/material-design-everywhere/ , but I get errors like "attribute transitionName, used only in api level 21 or higher"

Answer 1

There are no compatible libraries supporting transitions of shared elements. The best you can do is use the approach described in this video ... however, note that implementation requires a lot more code.
