Single Sign On for Android Facebook

Posted by: admin June 15, 2020 Leave a comment


I need to know much about Single Sign On support for Facebook. I have two applications on my device and I have to post the feed. I login the very first time from either one of the applications, but I need it to continue using the same login credential and session for the other application without showing the login page. Is this possible in android? If so please guide me how to implement it.

Thanks in advance.

How to&Answers:

Make sure both apps reference the same Facebook app client_id and client_secret. Once the user authorizes one of your Android apps, store their access_token, and share it between both apps.


Perhaps see

Preserving login session across multiple Android apps

and then

Write a private access file to another app's files directory

My solution is to write the login information (I guess access_token) to a file on both apps and make each app check it’s file and the other app’s file modification time. the one modified most recent wins.

You would have to write up some code for that..
