Android: Thumbnail stored in DB is returned null

I have a Db where I have stored the path of a video and its thumbnail in ByteArray form. But when I try to retrieve the thumbnail from the DB I always get null value. Here is the code I am using to retrieve both the thumb and the path:

        db=openOrCreateDatabase("VideoPaths", Context.MODE_PRIVATE, null);
        db.execSQL("CREATE TABLE IF NOT EXISTS paths(path VARCHAR,thumbnail BLOB);");
        Cursor c = db.rawQuery("SELECT path,thumbnail FROM paths",null);
        int index = c.getColumnIndex("path");
        int index2 = c.getColumnIndex("thumbnail");

        c.moveToFirst();

            if (c != null) {
                // Loop through all Results
                do {

                    String VideoPath = c.getString(index);
                    byte[] bytes = c.getBlob(index2);
                    Bitmap thumb = BitmapFactory.decodeByteArray(bytes, 0, bytes.length);


                    pathList.add(VideoPath);
                    listRow.add(new VideoRow(VideoPath,thumb, "User", "Testing"));

                } while (c.moveToNext());
            }

Do you have any ideas on how to fix this issue ?

P.S The video path retrieval is working fine.
