    It is working in my case

    Uri videoUri = data.getData();
                    String selectedPathVideo="";
                    selectedPathVideo = ImageFilePath.getPath(getApplicationContext(), videoUri);
                    Log.i("Image File Path", ""+selectedPathVideo);
    
                    try {
                        Bitmap thumb = ThumbnailUtils.createVideoThumbnail(selectedPathVideo, MediaStore.Video.Thumbnails.MICRO_KIND);
    
    
                        imgFarmerVideo.setImageBitmap(thumb);
    
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
    

    The Support File

    Try ThumbnailUtils, to get video bitmap from file path

    ThumbnailUtils.createVideoThumbnail(filePath,MediaStore.Video.Thumbnails.MINI_KIND);

    It is possible to get thumbnail image of video from video url.

    If your video type is Vimeo follow below steps:

    1)Suppose your Video Url is: http://player.vimeo.com/video/17314292

    2)Get Video Id From Url : eg. 17314292

    3)Call WS with Video id and XMl format http://vimeo.com/api/v2/video/17314292.xml

    You will get "thumbnail_small","thumbnail_medium","thumbnail_large" in xml format for video thumb from video id

    If your video type is YouTube follow below steps:

    1)Video Url : http://www.youtube.com/embed/Nl2iMF0yKW8

    2)Get Video Id From Url : eg. Nl2iMF0yKW8

    3)Replace video id in this url http://i3.ytimg.com/vi/Nl2iMF0yKW8/default.jpg

    NOTE:Just replace your id here.

    It's very important to identify the components of a problem. I'd actually say you have two separate problems:

    1. Downloading a file from an URL.

    2. Creating a thumbnail image from an incomplete video file.

    Look into those two separately, you'll find plenty of information.
