First Impressions of Android’s new ConstraintLayout
Mike Wolfson

thanks mike for this good article. i used it multiple time in different project. it is easy to use but it has many bugs yet. i don’t recommend it to use in serious project. i tested its performance in complex layouts recently but surprisingly it was slower than a layout with deep hierarchy that implemented with relative layouts.

also i developed a sample weather app to demonstrate its usage and combination with android design support library. you can check it out:
