Error inflating sectionindicator

[haroldoao]

android.view.InflateException:
Binary XML file line #25: Binary XML file line #25: Error inflating class xyz.danoz.recyclerviewfastscroller.sectionindicator.title.SectionTitleIndicator
....etc...
....etc...
....etc...
Caused by: android.view.InflateException: Binary XML file line #25: Error inflating class xyz.d

Does anyone know why exactly I'm getting this error?

I've imported the library correctly in gradle and it has no problem inflating / finding the "recyclerviewfastscroller.vertical.VerticalRecyclerViewFastScroller"

But it won't find the sectionindicator in the class

It's an abstract class. You have to extend it, copy the one from the example app, etc
