ERROR: In  MenuView, unable to find attribute android:preserveIco         


        

Answer 1

In my case for the same error, when all else failed, I removed this line from Gradle config file, myproject/app/build.gradle

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

and, voila! It worked.
