Please your code.

For me too when using in fragment.

Code is standard recyclerview in fragment with adapter like here:

I also started seeing these occasionally with recyclerview-animators-2.2.3, com.android.support:recyclerview-v7:23.4.0 on Genymotion (Nexus 5 running Android 5.1). As it stands right now, I can't reproduce it :-( Will add more details in case I can. Preventively adding android:focusableInTouchMode="true" and android:animateLayoutChanges="false" to my recyclerview, as hinted at from several stackoverflow threads.

This is my stack trace:

The fix which worked for me: do not reuse the same animator instance across multiple recycler view instances!

I had a static field referring the animator instance. I was creating two instances of the fragment containing the recycler view, but I also noticed the issue when the single fragment instance got recycled and a another instance created.

@renyedi Exactly the right answer!
