Answer 1

As I was using recycleview-multiselect, it has setSelectionModeStateListAnimator,setDefaultModeStateListAnimator, setSelectionModeBackgroundDrawable,setDefaultModeBackgroundDrawable set in SwappingHolder So after my super call to holder just set:

    if ( Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        setSelectionModeStateListAnimator(null);
        setDefaultModeStateListAnimator(null);
    }
    // Default selection mode background drawable is this
    setSelectionModeBackgroundDrawable(null);
    setDefaultModeBackgroundDrawable( null );

And used my own selectors in xml, this has resolved the crash.

Answer 2

Turning a comment on the question, by Etienne Lawlor, into an answer:

I am getting the same crash as @rrbrambley but it happens when i set android:enabled="false" on my Button in xml.

I verified that changing android:enabled="false" to android:enabled="true" solves this problem at least in my case.
