Shantanu-tec

I am using Same code in both Activity and Fragment and it is working in Activity but not in Fragment. Any remedy for this.?

SparseArray<YtFile> ytFiles returns null

1

if (ytFiles != null) { int itag = 18; String downloadUrl = ytFiles.get(itag).getUrl(); Uri url = Uri.parse(downloadUrl); playVideo(url); Log.d("shantanu",downloadUrl); }else{ Log.d("shantanu", String.valueOf(ytFiles)); }
