我正在使用 JSpreadSheet 从 SDCard 读取 xlsx 文件并尝试我可能无法让应用程序工作。我在 Java 中尝试了相同的代码，它完美地工作，将单元格输出到 system.out，但它似乎在 Android 中不起作用。请帮忙 ！

这是我的功能：

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();
                }





    }

我知道我应该使用 Environment 来访问 SDCard，但这不是现在的问题。我收到的警告是这些，应用程序崩溃并且根本无法在模拟器上运行。

他们有单独的 Android jar 文件。确保您使用 Android 的 jar 文件，而不是 Java SDK。
