MotionLayout allows us to define constraints by using `app:layoutDescription` attribute. That is helpful for animations too.

The attached MotionLayout uses this to define constraints and it is a layout we have over a year with no issues.

When I tried AGP 4.x, it has a lot of false-positives of `MissingConstraints`.

Layout and the Lint reports are attached.

Marked as fixed, reassigned to tn...@google.com.

Fixed by Change-Id: Idbdc08bf965b17817227e2de01e63c372a2bddb2 for 4.1 canary 4 (and will cherrypick over to 4.0 as well). Thanks for the report!
