As the namespace implies (tools:layout_constraintTop_creator), it's purely used by Android Studio -- those attributes (using the namespace tool) are actually stripped out when the xml file is pushed on a device.

So it shouldn't be used :)

Now if you want to know how Studio use those, it's actually simple: we use the creator attributes to keep track of who created the constraints, particularly if they are created by the inference engine, as we want to scrap them / replace them in some cases.

What are the different values? For example is a value of "1" the inference engine? – Lou Morda Apr 10 '17 at 17:50

Now (1.0.2) creator attribute is in `app` name space too.. What would that mean? – Samuel Robert Oct 19 '17 at 10:10
