How to make YouTube video thumbnails in android? [duplicate]

YouTube puts the thumbnails of the video at a specific predictable URL. It would be a bit of a pain, but I'm sure you could find a way to display the images from the URL, or to download them and then display them.

Here's information on my blog on what those thumbnail URLs are.

I'll copy and paste what I wrote in the blog post:

Look at the link for the video–for example, http://www.youtube.com/watch?v=GDFUdMvacI0

Take the video ID… the portion after “v=”, in this case GDFUdMvacI0. If the URL is longer than that, only go until the next ampersand. For example, http://www.youtube.com/watch?v=GDFUdMvacI0&feature=youtu.be is the same, GDFUdMvacI0.

Then just substitute your video ID for the video ID in the following URLs to these thumbnail images:

• http://img.youtube.com/vi/GDFUdMvacI0/0.jpg
• http://img.youtube.com/vi/GDFUdMvacI0/1.jpg
• http://img.youtube.com/vi/GDFUdMvacI0/2.jpg
• http://img.youtube.com/vi/GDFUdMvacI0/3.jpg

0.jpg is a full-sized image. The other three are very small (120×90) and are taken automatically by YouTube from three certain points in the video.

• Download picasso jar file and put that jar file in "libs" folder

• Use picasso to download image

• Use method extractYoutubeId(url) to extract youtube id from YoutubeVideo Url

To get image of youtube video use given link and put youtube id in that url as below: "http://img.youtube.com/vi/"+extractYoutubeId(url)+"/0.jpg"

Try this

public static String getYoutubeThumbnailUrlFromVideoUrl(String videoUrl) {   return "http://img.youtube.com/vi/"+getYoutubeVideoIdFromUrl(videoUrl) + "/0.jpg";}public static String getYoutubeVideoIdFromUrl(String inUrl) {   inUrl = inUrl.replace("&feature=youtu.be", "");   if (inUrl.toLowerCase().contains("youtu.be")) {       return inUrl.substring(inUrl.lastIndexOf("/") + 1);   }   String pattern = "(?<=watch\\?v=|/videos/|embed\\/)[^#\\&\\?]*";   Pattern compiledPattern = Pattern.compile(pattern);   Matcher matcher = compiledPattern.matcher(inUrl);   if (matcher.find()) {      return matcher.group();   }   return null;}
