From the Android Developer Documentation, ConstraintLayout allows you to create large and complex layouts with a flat view hierarchy (no nested view groups). It's similar to RelativeLayout in that all views are laid out according to relationships between sibling views and the parent layout, but it's more flexible than RelativeLayout and easier to use with Android Studio's Layout Editor.

Have you been wanting to know more about the new ConstraintLayout that is now a part of Android? If so, join us at the Armory for a presentation by Brian Sturgill where we will see an example of ConstraintLayout and explore this new addition in Android UI Development.
