为什么XSSFworkbook对象无法在android 4.4及更低版本中运行

Question

我在使用我的应用程序与org.apache.poi.POIXMLException合并后运行我的模块时遇到此异常：java.lang.reflect.InvocationTargetException

 OPCPackage pkg = OPCPackage.open(temp);
            XSSFWorkbook workbook = new XSSFWorkbook(pkg);
            numberOfSheet = workbook.getNumberOfSheets();
            for (int i = 0; i < workbook.getNumberOfSheets(); i++) {
            XSSFSheet sheet = workbook.getSheetAt(i);
            int rowsCount = sheet.getPhysicalNumberOfRows();
            FormulaEvaluator formulaEvaluator=   workbook.getCreationHelper().createFormulaEvaluator();
                for (int r = 0; r < rowsCount; r++) {
                    Row row = sheet.getRow(r);
                    int cellsCount = row.getPhysicalNumberOfCells();
                    for (int c = 0; c < cellsCount; c++) {
                 String value = getCellAsString(row, c, formulaEvaluator);
                        al.add(new ExcelValues(i, r, c, value));
                    }
                }
            }

这在Android 5.0及更新版本中运行完美，并且在单独的应用程序中也是如此。

这是我得到的致命错误消息
