我有一个非常奇怪的错误,使用 apache poi,我认为它与 ooxml-schemas--.jar 文件有关。我基本上是在尝试将 xlsx 文件读入内部存储,但这并没有发生。
详细信息:我正在使用 Apache Poi 3.9 从 android 中的 res.raw 文件夹中读取它是一个 xlsx 文件,它使用 Outputstream 将自己应对到 android 中的内部存储。它只是没有发生。这是错误日志:

到底发生了什么?
这是我正在使用的功能:
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
readAndWrite();
}
public void readAndWrite() {
try
{
// Read from original Excel file. //Get from RawResources in Android
InputStream inputStream = getResources().openRawResource(R.raw.ems_data);
OutputStream fos = openFileOutput("ems_data.xlsx", Context.MODE_PRIVATE);
Workbook workbook = WorkbookFactory.create(inputStream );
// Get the first sheet.
Sheet sheet = workbook.getSheetAt(0);
// Set value of the first cell.
Row row = sheet.getRow(0);
Cell cell = row.getCell(0);
cell.setCellValue("Xuan");
// Write newly modified workbook to a file. //Copy to Internal Storage in Android
// FileOutputStream fileOut = new FileOutputStream("/sdcard/ems_data3new.xlsx");
workbook.write(fos);
fos.close();
}
