          for (int i = 0; i < cursor.getCount(); i++) {//c.getCount()
              String date = cursor.getString(cursor.getColumnIndexOrThrow("date")).toString();
              String number = cursor.getString(cursor.getColumnIndexOrThrow("address")).toString();
              String body = cursor.getString(cursor.getColumnIndexOrThrow("body")).toString();
              String type = cursor.getString(cursor.getColumnIndexOrThrow("type")).toString();

  cursor.close();
}


Get Videos

      int actual_image_column_index = cursor.getColumnIndexOrThrow(MediaStore.Video.Media._ID);

      for (int i = 0; i < cursor.getCount(); i++) {
          cursor.moveToPosition(i);
          String fileName = cursor.getString(actual_image_column_index);
          fileList.add((Uri.withAppendedPath(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, fileName)));
      }
      return fileList;
  } catch (Exception e) {
      return null;
