The app crashes while the activity is launching

[abh006]

I was trying this library as per the readme.md
I added that dependency and the repository jcenter() already existed
In the layout file I added the tag as given in the readme

Actual Behavior

The app crashes while the activity is loading

Caused by: android.view.InflateException: Binary XML file line #9: Binary XML file line #9: Error inflating class devs.mulham.horizontalcalendar.HorizontalCalendarView

[aalap03]

this is because of using this library in project supporting andoridX, this library is not working with androidX even after enabling jetifier in gradle.properties.
