Java 使用JSpreadsheet时遇到警告和错误

我正在使用JSpreadSheet从SD卡读取xlsx文件，并尽我所能尝试使应用程序无法运行。我在Java中尝试过同样的代码，它工作得非常完美，将单元格输出到system.out，但在Android中似乎不起作用。请帮忙

以下是我的功能：

public void readAndDisplay(){





                try
                {
                    Workbook book = new Workbook("/sdcard/new.xlsx");

                    for (Sheet sheet : book.getSheets())
                    {
                        if (sheet instanceof Worksheet)
                        {
                            Worksheet worksheet = (Worksheet)sheet;
                            List<Cell> cells = worksheet.getCells();

                            for (int i = 0; i < cells.size(); i++)
                            {
                                System.out.println(cells.get(i).getReference() + " = " + cells.get(i).getValue());
                            }
                        }
                    }
                }
                catch (Exception e)
                {
                    System.out.println(e.getMessage());
                    e.printStackTrace();
                }





    }

public void readAndDisplay（）{
尝试
{
工作簿=新工作簿（“/sdcard/new.xlsx”）；
for（工作表：book.getSheets（））
{
if（工作表的工作表实例）
{
工作表工作表=（工作表）工作表；
列表单元格=工作表。getCells（）；
对于（int i=0；i

我知道我应该使用环境来访问SD卡，但这不是现在的问题。我得到的警告是，应用程序崩溃，根本无法在模拟器上运行
