I'm using RecyclerView and none of the presented solutions worked. I got the error when removing items.

What did work was overriding the Adapter's 'onItemDismiss(int position)' so that it first does a 'notifyDataSetChanged()' prior to removing the item and then does 'notifyItemRemoved(position)' after removing the item. Like this:

// Adapter code
@Override
public void onItemDismiss(int position) {
    if (position >= 0 && getTheList() != null && getTheList().size() > position) {
        notifyDataSetChanged();  // <--- this fixed it.
        getTheList().remove(position);
        scrollToPosition(position);
        notifyItemRemoved(position);
    }
}

Also do an Override of 'removeAt(int position)' in the TabFragment to invoke the new cleanup code, like this:

// TabFragment code
@Override
public void removeAt(int position) {
    mAdapter.onItemDismiss(position);
    mAdapter.notifyItemRemoved(position); // <--- I put an extra notify here too
}
