Getting Null pointer Exception

[cr7rahul]

`public void add(MovieListItem r) {
movieResults.add(r);
notifyItemInserted(movieResults.size() - 1);
}

public void addAll(List<MovieListItem> moveResults) {
    for (MovieListItem result : moveResults) {
        add(result);
    }
}`

on debugging i found out that in addAll method the movieResults are fetched correctly. But in add(MovieListItem) method the r values becomes null
