Answer 1

Got a better solution from this link.

Use the following method to get the videoId from the link.

YoutubeHelper.java

import com.google.inject.Singleton; 

import java.util.regex.Matcher;
import java.util.regex.Pattern;

@Singleton 
public class YouTubeHelper { 

    final String youTubeUrlRegEx = "^(https?)?(://)?(www.)?(m.)?((youtube.com)|(youtu.be))/";
    final String[] videoIdRegex = { "\\?vi?=([^&]*)","watch\\?.*v=([^&]*)", "(?:embed|vi?)/([^/?]*)", "^([A-Za-z0-9\\-]*)"};

    public String extractVideoIdFromUrl(String url) {
        String youTubeLinkWithoutProtocolAndDomain = youTubeLinkWithoutProtocolAndDomain(url);

        for(String regex : videoIdRegex) {
            Pattern compiledPattern = Pattern.compile(regex);
            Matcher matcher = compiledPattern.matcher(youTubeLinkWithoutProtocolAndDomain);

            if(matcher.find()){
                return matcher.group(1);
            } 
        } 

        return null; 
    } 

    private String youTubeLinkWithoutProtocolAndDomain(String url) {
        Pattern compiledPattern = Pattern.compile(youTubeUrlRegEx);
        Matcher matcher = compiledPattern.matcher(url);

        if(matcher.find()){
            return url.replace(matcher.group(), "");
        } 
        return url;
    } 
} 

Hope this helps.

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;
 }

Answer 3

This was worked for me

public static String getYoutubeVideoId(String youtubeUrl) {
    String videoId = "";
    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?=?([^#\&\?]*).*/;
        Pattern pattern = Pattern.compile(expression,Pattern.CASE_INSENSITIVE);
        Matcher matcher = pattern.matcher(youtubeUrl);
        if (matcher.matches()) {
            String groupIndex1 = matcher.group(7);
            if(groupIndex1!=null && groupIndex1.length()==11)
                videoId = groupIndex1;
        }

    }
    return videoId;
}
