Android shared elements transition pre-21 [duplicate]

Question

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

Answer 1

There is no compatibility libraries that support shared element transitions. The best you can do is use the approach described in this video... however, note that it takes a lot more code to implement.
