Calendar that supports iCal??

My wide has a web Google calendar with a subscribed iCal calendar (listed under Other Calendars). Works great. She cannot get the subscribed calendar to show up on any Android calendar (default or downloaded). Is this supported?

I have the same subscribed calendar linked to my Outlook calendar and shows up perfectly on my iPhone. All I had to do was click the "subscribe" link provided by the author of the calendar. When I do this on my wife's Android, every time it says the web page is unavailable. I've talked to others, and researched the web, and can't find any examples of people who have done this successfully.

If I could find where to manually add a subscribed calendar, I'd simply copy/paste the URL...but I can't find where to add a calendar.

Help...
