Try this code here.

// (?:youtube(?:-nocookie)?\.com\/(?:[^\/\n\s]+\/\S+\/|(?:v|e(?:mbed)?)\/|\S*?[?&]v=)|youtu\.be\/)([a-zA-Z0-9_-]{11})
final static String reg = "(?:youtube(?:-nocookie)?\\.com\\/(?:[^\\/\\n\\s]+\\/\\S+\\/|(?:v|e(?:mbed)?)\\/|\\S*?[?&]v=)|youtu\\.be\\/)([a-zA-Z0-9_-]{11})";

public static String getVideoId(String videoUrl) {
    if (videoUrl == null || videoUrl.trim().length() <= 0)
        return null;

    Pattern pattern = Pattern.compile(reg, Pattern.CASE_INSENSITIVE);
    Matcher matcher = pattern.matcher(videoUrl);

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