Android : What are the steps to minimise making requests for user data with the Facebook Android SDK?

I have been going through the tutorials on using the Facebook Android SDK.

I noticed that it makes the asynchronous request to get the info whenever the onCreateView is called:

Session session = Session.getActiveSession(); if (session != null && session.isOpened()) { // Get the user's data makeMeRequest(session); }

So whenever a configuration change is made (orientation) or it create the fragment navigating back from another activity it makes the request.

I think that this is a waste of network usage and time as all I need is the profile picture, name and email. These values do not usually change very frequently.

I think one way is to make the request once each time an authenticated user opens the app. Then cache the data or use SharedPreferences from that point onwards.

I am storing one image and two text fields.

How should I do this?
