Summary

This chapter covered creating animations and transitions with CoordinatorLayout and MotionLayout. Animations can improve the usability of our app and make it stand out compared to other apps.

We started by customizing the transition when opening and closing an activity with activity transitions. We also learned about adding shared element transitions when an activity and the activity that it opens both contain the same elements so that we can highlight this link between the shared elements to the users.
