Upgrading from 1.6.x to 2.1.0 is now throwing an inflation error

While debugging, the inflator is throwing an exception at the buttonPast code in MaterialCalendarView:

    topbar = content.findViewById(R.id.header);
    buttonPast = content.findViewById(R.id.previous); <-- 
    title = content.findViewById(R.id.month_name);
    buttonFuture = content.findViewById(R.id.next);
    pager = new CalendarPager(getContext());

That immediately drops into the android’s LayoutInflator with an exception:

        } catch (Exception e) {
            final InflateException ie = new InflateException(
                    attrs.getPositionDescription() + ": Error inflating class "
                            + (clazz == null ? "<unknown>" : clazz.getName()), e);
            ie.setStackTrace(EMPTY_STACK_TRACE);
            throw ie;

The exception:

java.lang.NoSuchFieldError: No static field previous of type I in class Lcom/prolificinteractive/materialcalendarview/R$id; or its superclasses (declaration of 'com.prolificinteractive.materialcalendarview.R$id' appears in /data/app/xx/split_lib_slice_4_apk.apk)

The best I can tell is that there is another module using the id of ‘previous’ that is colliding with material-calendarview. I cannot find where that could be happening. Everything was working in 1.6.0.

I figured it out. There is a collision between this lib and https://github.com/Applandeo/Material-Calendar-View. We’re running both for different purposes. Any chance you could make your xml ids a bit more specific?

There seems to be a number of people experiencing this issue or at least are having inflation errors:. #955 #944 #942 #938
