Answer 1

public static String getYoutubeVideoId(String youtubeUrl)
 {
 String video_id="";
  if (youtubeUrl != null && youtubeUrl.trim().length() > 0 && youtubeUrl.startsWith("http"))
 {

String expression = "^.*((youtu.be"+ "\\/)" + "|(v\\/)|(\\/u\\/w\\/)|(embed\\/)|(watch\\?))\\??v?=?([^#\\&\\?]*).*"; // var regExp = /^.*((youtu.be\/)|(v\/)|(\/u\/\w\/)|(embed\/)|(watch\?))\??v?=?([^#\&\?]*).*/;
 CharSequence input = youtubeUrl;
 Pattern pattern = Pattern.compile(expression,Pattern.CASE_INSENSITIVE);
 Matcher matcher = pattern.matcher(input);
 if (matcher.matches())
 {
String groupIndex1 = matcher.group(7);
 if(groupIndex1!=null && groupIndex1.length()==11)
 video_id = groupIndex1;
 }
 }
 return video_id;
 }
