First You have to go to this link, from which you can download latest library:

http://www.apache.org/dyn/closer.cgi/poi/release/bin/poi-bin-3.9-20121203.tar.gz

After that Put below code on onCreate or onResume Mehod:

HSSFWorkbook workbook = new HSSFWorkbook();
HSSFSheet firstSheet = workbook.createSheet("Sheet No: 1");
HSSFSheet secondSheet = workbook.createSheet("Sheet No: 2");
HSSFRow rowA = firstSheet.createRow(0);
HSSFCell cellA = rowA.createCell(0);
cellA.setCellValue(new HSSFRichTextString("Sheet One"));
HSSFRow rowB = secondSheet.createRow(0);
HSSFCell cellB = rowB.createCell(0);
cellB.setCellValue(new HSSFRichTextString("Sheet two"));
FileOutputStream fos = null;
try {
    String str_path = Environment.getExternalStorageDirectory().toString();
    File file ;
    file = new File(str_path, getString(R.string.app_name) + ".xls");
    fos = new FileOutputStream(file);
    workbook.write(fos);
} catch (IOException e) {
    e.printStackTrace();
} finally {
    if (fos != null) {
        try {
            fos.flush();
            fos.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    Toast.makeText(MainActivity.this, "Excel Sheet Generated", Toast.LENGTH_SHORT).show();
}

// To see this excel file go to File Explorer in eclipse -> SDCard Path -> Excel.xls -> Pull it -> See it.
