Hi, has anyone experienced problems with FragmentPagerAdapter when overriding setPrimaryItem() after updating the support library to version 27.0.0. The signature changed from setPrimaryItem(container: ViewGroup, position: Int, obj: Any?) to setPrimaryItem(container: ViewGroup, position: Int, obj: Any). It's causing an illegal argument exception because obj is null.

Maybe you should post an issue on b.android.com?

While the documentation is a bit vague the concept is that you should return non-null values from instantiateItem. If you return null isViewFromObject will also not work properly.
