Я использую JSpreadSheet для чтения файла xlsx с SDCard и стараюсь, чтобы я не мог заставить приложение работать. Я пробовал один и тот же код на Java, и он работает безупречно, выводя ячейки в system.out, но он, похоже, не работает в Android. Пожалуйста помоги !Выполнение предупреждений и ошибок с использованием JSpreadsheet
Вот моя функция:
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();
}
}
Я знаю, что я должен использовать среду, чтобы добраться до SDCard, но это не проблема сейчас. Предупреждения, которые я получаю, это, приложение вылетает и вообще не запускается на эмуляторе.
