ExpandableBottomBar.java || Line 399

      if (pos == mMoreTabPosition && mAllTabsVisible == false) {
                setBtmTabsVisibility(btmTabContainers, View.VISIBLE);
                mAllTabsVisible = true;
                ValueAnimator btm = ValueAnimator.ofFloat(0, topTabContainer.getHeight());
                btm.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
                    @Override
                    public void onAnimationUpdate(ValueAnimator valueAnimator) {
                        float val = (float) valueAnimator.getAnimatedValue();
                        LinearLayout.LayoutParams p = new LayoutParams(btmTabContainers[0].getLayoutParams().width, (int) val);
                        setLayoutParamsToBtmTabs(btmTabContainers, p);
                    }
                });
                 
               // Custom
                TabInformation tf =  mTabInfoList.get(pos);
                tf.title = "Down";
                tf.iconResId = ArrowDownIconRecId;
                tf.notify(); //  notify() is showing error something like:
                java.lang.IllegalMonitorStateException: object not locked by thread before notify()

                btm.setDuration(mAnimationDuration);
                btm.start();
            }

Its also not working

   changeTab(mMoreTabPosition,"helo");

        public void changeTab(int position, String title){
            TabInformation tabInformation =  mTabInfoList.get(position);
            tabInformation.iconResId = des_mMoreIconRecId;
            tabInformation.title = title;
            Toast.makeText(mContext,"tabInformation : "+tabInformation,Toast.LENGTH_SHORT).show();
        }
