Now that you can download google calendar it is great to have the option to use it. However, when you receive an ICS file from Outlook to Android it will only process using the stock calendar and doesn't give the option to use the Google Calendar. Does anyone know if a way to fix this? I've tried looking for file associations but it pops up the box when I click to open the invite.ics file and an option doesn't exist for Stock google calendar . Any ideas? I am rooted, but I would like a non-root solution, if possible.
