I dont think u can generate the thumbnail of the video by just giving the video link to the ThumbnailManager,

2 approaches which i can suggest is

1. The server which is storing the video should store the thumbnail of the video as well so that u can directly download the thumbnail image
2. download video and get thumbnail out of that.This approach is not right anyways.

If you are using some third party server eg. youtube or something then they will be having the separate link for thumbnail of video.

If your video link is server link then use below code

To get thumbnail from the URL, i only got one solution till now, You have to use This library

It Supports file, http, https, mms, mmsh and rtmp protocols Supports aac, acc+, avi, flac, mp2, mp3, mp4, ogg, 3gp and more! formats (audio and video):

Check this one..

Replace VIDEO_ID with video id. e.g: http://img.youtube.com/vi/z99cgIIVuyo/default.jpg

Define your server link,

String path = "http://yourSeverLink/foldername/test.mp4";

then take one imageview like,

ImageView video_thumbnail;
Bitmap bm;

and define in onCreate method.

video_thumbnail = (ImageView) findViewById(R.id.video_one);

now for getting thumbnail use this,

bm = ThumbnailUtils.createVideoThumbnail(path,
                    MediaStore.Images.Thumbnails.MICRO_KIND);
// For setting that thumnail to imageview use this below code
video_one.setImageBitmap(bm);
