If a Recycle view inside in a NestedScrollView, The times of calling recyclerView#onCreateViewHolder() is requal to its data set. When there are large set of apps need to be shown, RecyclerView will need to take many time to call onCreateViewHolder for each item. So, it causes the screen is janky or freeze UI when page is loading large data set. For now, we get rid of NestedScrollView, just use RecycleView and AppBarLayout to have same bahavior for spinner.
