Trying to run app on android, fails

Capacitor
1

the page flashes and I get this error in the log

java.lang.RuntimeException: Unable to start activity ComponentInfo{io.ionic.starter/io.ionic.starter.MainActivity}: android.view.InflateException: Binary XML file line #2: Binary XML file line #2: Error inflating class android.support.design.widget.CoordinatorLayout

ionic capacitor build android succeeds and launches android studio, then run on fails.

did I miss a build step?

apparently something was downlevel


using jetify fixed whatever it was.
