Firebase and Google Calendar

[Steven Ferrarese]

So  I have been asked to make an app for my town, and the one problem I am having is trying to figure out how to get events off of the towns calendar and schools calendar, and put it into one on the app.  I understand that I can just update my firebase database with the events and read them into the app that way.  But is there a way to have the firebase database read data off the a google calendar and put it in the database and structure it. Or have the app read in data from the google calendar? 

Thanks in advance !

Steven,

Firebase won't be of direct help you to.  Have you explored the Google Calendar APIs?  You have several options to access calendar data.  https://developers.google.com/google-apps/calendar/

I am doing something very similar, I am trying to authenticate with firebase and then connect to the calendar API. Unfortunately there is a significant problem that I haven't found an answer to yet. The problem is with the access_token. When login to firebase using Google credentials, it gives you back the google access_token, which is great. Unfortunately, that token only last for an hour and you're NOT given a refresh token, which means while your app is still authenticated against firebase after an hour you can no longer access the google apis without forcing the user to login again.

After much searching I have not found any great solution to this. If you're interested, I'll post a solution when/if I find one.

Jacob,

The Firebase SDK will automatically refresh that token as needed.  Have you using the most recent every time, rather than holding on to the one you get first?  A token refresh is one of the conditions that causes an AuthStateListener to trigger - you might want to capture it every it indicates a user is logged in.

Actually, Jacob (not me, the other Jacob) and Doug are referring to different tokens here. The Firebase SDKs will automatically refresh Firebase ID tokens, but not Google access tokens. There is no way to currently do this with the current SDKs that I am aware of, unless you roll your own Google OAuth flow using custom authentication.

The Firebase Auth team is aware of this limitation and has longterm plans to address it. I'll forward this thread on to them so they know users like yourself would like to see it happen.

Cheers,

Jacob

Hi All,

I am currently facing the same issue - has this been resolved at all? Can I use standard firebase google login? or if there is a custom solution to this - I am using Kotlin and trying to implement for an Android app

Thanks
