I'm using a dependency on an agenda with github calendar

link

but at the time of declaring the view sends me the following notice in the xml

and in the second error

The following classes could not be instantiated:

- com.github.tibolte.agendacalendarview.agenda.AgendaListView (Open Class, Show Exception, Clear Cache)
