I have been hunting for ages trying to determine what format of calendar invite/event an Android device can download and incorporate into the system calendar - however I have not been able to locate anything!
By default the device does not support iCal or vCal - and the formats for both of these are well defined and easy to create. For example, this PHP script works perfectly for an iPad or an iPhone - so when you visit the page, the device invites you to add it to your calendar:
<?
$ical = "BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//hacksw/handcal//NONSGML v1.0//EN
BEGIN:VEVENT
UID:" . md5(uniqid(mt_rand(), true)) . "@yourhost.test
DTSTAMP:" . gmdate('Ymd').'T'. gmdate('His') . "Z
DTSTART:19970714T170000Z
DTEND:19970715T035959Z
SUMMARY:Bastille Day Party
END:VEVENT
END:VCALENDAR";
header("Content-type: application/force-download");
header('Content-Disposition: attachment; filename=calendar.ics');
echo $ical;
exit;
?>
I'm trying to create something similar for Android, but am unable to find any guidance on what file it will happily download natively, without some third party apps!
Any ideas or help appreciated!
Thanks, Kaiesh
