Android how can i get thumb image of video file from gallery

Question

I need to show the selected video file from gallery in my listview. I have successfully fetched the uri of video file but i am not able to get the thumb image of video file. Here is the code i have used for fetching image of video file from uri, but is causes the app to crash. Is there any other way to get image of video file..? please assist me if it can be achieved in any other way....

public static String getFileMetaData(Context context,String uri){
        Uri queryUri = Uri.parse(uri);
        // Get relevant columns for use later.
        String[] projection = {
                MediaStore.Files.FileColumns._ID,
                MediaStore.Files.FileColumns.DATA,
                MediaStore.Files.FileColumns.DATE_ADDED,
                MediaStore.Files.FileColumns.MEDIA_TYPE,
                MediaStore.Files.FileColumns.MIME_TYPE,
                MediaStore.Files.FileColumns.TITLE
        };
// Return only video and image metadata.
        String selection = MediaStore.Files.FileColumns.MEDIA_TYPE + "="
                + MediaStore.Files.FileColumns.MEDIA_TYPE_IMAGE
                + " OR "
                + MediaStore.Files.FileColumns.MEDIA_TYPE + "="
                + MediaStore.Files.FileColumns.MEDIA_TYPE_VIDEO;

        CursorLoader cursorLoader = new CursorLoader(
                context,
                queryUri,
                projection,
                selection,
                null, // Selection args (none).
                MediaStore.Files.FileColumns.DATE_ADDED + " DESC" // Sort order.
        );

        Cursor cursor = cursorLoader.loadInBackground();
        int columnIndex = cursor.getColumnIndex(MediaStore.Video.Thumbnails.DATA);

        Log.d("MyTag","***************** : " + cursor.getString(columnIndex));

        cursor.close();
        return null;
    }

Fixed this problem with some changes. Actually my problem was the file path that i had given is wrong.I have been giving the Uri got from gallery, now i had changed the code for getting the real path from Uri and then applied them to ThumbnailUtils for creating thumb image.

Uri uri = Uri.parse(uri);
String mUri = AppUtils.getRealPathFromURI(mActivity,uri,"VIDEO");
mImageSend.setImageBitmap(ThumbnailUtils.createVideoThumbnail(
                            mUri, MediaStore.Video.Thumbnails.FULL_SCREEN_KIND));


public static String getRealPathFromURI(Context context,Uri contentURI,String type) {

        String result  = null;
        try {
            Cursor cursor = context.getContentResolver().query(contentURI, null, null, null, null);
            if (cursor == null) { // Source is Dropbox or other similar local file path
                result = contentURI.getPath();
                Log.d("TAG", "result******************" + result);
            } else {
                cursor.moveToFirst();
                int idx = 0;
                if(type.equalsIgnoreCase("IMAGE")){
                    idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
                }else if(type.equalsIgnoreCase("VIDEO")){
                    idx = cursor.getColumnIndex(MediaStore.Video.VideoColumns.DATA);
                }else if(type.equalsIgnoreCase("AUDIO")){
                    idx = cursor.getColumnIndex(MediaStore.Audio.AudioColumns.DATA);
                }
                result = cursor.getString(idx);
                Log.d("TAG", "result*************else*****" + result);
                cursor.close();
            }
        } catch (Exception e){
            Log.e("TAG", "Exception ",e);
        }
        return result;
    }
