    ArrayList<Long> cellIds = new ArrayList<Long>();
    for (int i = 0; i < cells.size(); i++) {

        S2CellId cellId = cells.get(i);

        // can happen for some reason
        if (cellId.level() < minLevel || cellId.level() > maxLevel)
            continue;

    }

    // convert to hex values
    String cellIdsHex[] = new String[cellIds.size()];
    for (int i = 0; i < cellIdsHex.length; i++) {
        cellIdsHex[i] = Long.toHexString(cellIds.get(i));
    }
