calendar keeps causing app to force close

[armyofpunk]

I have implemented the agedacalendaras per readme, I have included your example events just as a place holder untill I get it set up and everytime I open it in app the app crashes. ...

here is the log

I don't have your code but seeing this:
java.lang.NullPointerException: Attempt to invoke virtual method 'void com.github.tibolte.agendacalendarview.AgendaCalendarView.init(java.util.List, java.util.Calendar, java.util.Calendar, java.util.Locale, com.github.tibolte.agendacalendarview.CalendarPickerController)' on a null object reference

Your instance of AgendaCalendarView is probably null. Check if you identified it from your layout.
Do you have something like:
mAgendaCalendarView = (AgendaCalendarView) findViewById(R.id.agendacalendarview);
before calling the init method?

ok mAgendaCalendarView is definitely null, please identify this view from your layout!

An example:

mAgendaCalendarView = (AgendaCalendarView) findViewById(R.id.agendacalendarview);
