Android: ArithmeticException in StaggeredGridLayoutManager

Question

My app works fine with almost android versions. But, in Crashlytics and in some devices, I have this crash: "java.lang.ArithmeticException: divide by zero". Its almost (if not always) in Android 4.x.

I have a StaggeredGridLayoutManager in a RecyclerView (SuperRecyclerView).

Stack trace:

I don't know what kind of information is needed to approach this problem, so please ask me whatever you need so I can update the question.

Any solution to this? I am currently receiving this same error. I'm even hard setting the SpanCount — C. Skjerdal, Jan 09 '19 at 22:06

Saw it, too, but on Android 5 and 7 as well. I checked the code and apparently it crashes when mSpanCount is 0. Unlike GridLayoutManager, StaggeredGridLayoutManager's setSpanCount doesn't check whether it's 1 or greater, and simply crashes later. In my case, the span count was 0 because I made it depend on the screen size, which seems to be 0 in rare cases.
