Check your build.gradle file, make sure the below dependency is added

compile 'com.android.support.constraint:constraint-layout:1.0.2'

Super! My build.gradle was showing implementation 'com.android.support.constraint:constraint-layout:1.0.2'. I just changed implementation to compile and it worked like a charm.

juan Isaza Over a year ago

compile is deprecated now, and should be replaced by implementation or api

Add the implementation 'com.android.support.constraint:constraint-layout:1.0.2' in the gradle file.

I got this error after a migration to androidx: the system had changed the build.gradle entry to the androidx library but not the xml files. Manually changing the xml opening tag to the relevant androidx name solved it.
