问题
In my android app, I have 3 login options. Google+, Facebook, and my own login option. I've implemented all 3.
I've implemented Facebook login via their v3.0 sdk. I open a Session, get an Access Token and the user's id. I then pass these 2 values to my api and log them in.
After getting those 2 values, I have no other use for facebook and I want to close the Session. Is there any reason I should leave it open?
I have a similar question for GoogleApiClient here.
