Did you manage to solve this issue? – Tympanic
You have initialized your ArrayListbut it has no elements in it. – Nazarius
How you fixed this? Thx. – Grimaldi

If your RecyclerView is in a Fragment and your Fragment is in ViewPager, and you didn't set viewpager.setOffscreenPageLimit(MAX_ITEM_SIZE), this crash will some times happen unexpectedly.

I was suffering same crashes. I can't reproduce it, and don't know why it would happen till now. But after I set the off-screen page limit, this crash goes away.

Wish it helps.

It's part of StaggeredGridLayoutManager.java

  /**
     * Checks for gaps in the UI that may be caused by adapter changes.
     * <p>
     * When a full span item is laid out in reverse direction, it sets a flag which we check when
     * scroll is stopped (or re-layout happens) and re-layout after first valid item.
     */
    boolean checkForGaps() {
        if (getChildCount() == 0 || mGapStrategy == GAP_HANDLING_NONE || !isAttachedToWindow()) {
            return false;
        }
        final int minPos, maxPos;
        if (mShouldReverseLayout) {
            minPos = getLastChildPosition();
            maxPos = getFirstChildPosition();
        ....

For a workaround, we can prevent StaggeredGridLayoutmanager.hasGapsTofix() call (which is the reason for this crash).

staggeredGridLayoutmanager.gapStrategy = StaggeredGridLayoutManager.GAP_HANDLING_NONE

But this option disables unexpected gap handling.

I had similar issue. In my case i had one "parent" RecyclerView and one of its items had its own "child" RecyclerView with StaggeredGridLayoutManager. Crash was happening when ViewHolder connected to this item was recycled. Setting up RecyclerView.ViewHolder.setIsRecyclable(false) on this ViewHolder fixed the issue for me

If your data is coming from any external source or API, then try using postDelayed() method when updating or initializing the recycler view, In my case this solved the error.

val handler = android.os.Handler()
handler.postDelayed({
    RecyclerViewAdapter!!.update(ArrayList<SearchNewModel>)
}, 200)
