notifySectionItemChanged() crashes the app

[rex50]

For the below code snippet, whenever onFinish is called and I try to notify adapter I'm getting exception mentioned below the code snippet.

CODE SNIPPET in Adapter

itemViewHolder.countDownTimer = new CountDownTimer(leftTime, 1000) {
    @Override
    public void onTick(long > millisUntilFinished) {
		//TODO
    }
    @Override
    public void onFinish() {
        viewHolder.setIsRecyclable(true);
        if(!fragment.isRecyclerComputingOrScrolling())
            notifySectionItemChanged(sectionIndex,itemIndex);
        else
            Log.e(TAG, "onFinish: recycler view is computing or scrolling");
    }
}.start();

EXCEPTION for above code snippet
