This is very perplexing. The crash is happening because the adapter
reference is null:
int getViewType(View view) {
int adapterPosition = getViewAdapterPosition(view);
return adapter.getItemViewType(adapterPosition);
}
There are only two ways the adapter may be null. The adapter reference is assigned in StickyHeaderLayoutManager::onAttachedToWindow
and is nulled in StickyHeaderLayoutManager::onDetachedFromWindow
So, the recyclerview has never been attached to window, or it was at some point detached - but it's still attempting to vend items.
Out of curiousity - did this work at some point, and later stop working as you added features? Or did this never work? I'm curious how to track this down, because, of all the many bugs I encountered developing this, this never happened.

Yeah you right, my recyclerview attached to window before setAdapter because I was inflate my view in onCreateView and set adapter onViewCreated method so remove onViewCreated than bug is gone :)

Can you go into more detail as to how you fixed this bug @ihsanbal? I am experiencing it in my activity as well. I have work that occurs in the background, after the async task finishes, it sets the RecyclerView adapter. This crash occurs if I am using the StickyLayoutManager, but not when using LinearLayoutManager.
Thnks
