Facebook graph API 'friends' request now only returning 25 friends per page? What's going on?

Question

My application(game) has been running on Facebook for some time. I start by requesting a friends list via the graph API call: my-uid/friends asking for user name and profile pic.

Normally I get back a list of all my friends up to a few thousand, until it starts putting friends on to the next page. Which is nice as most of my users get friends in 1 call.

Suddenly however, and with no changes to the app. about 40 minutes ago (18:40 Tuesday (PDT) - 2nd May 2012) I started getting responses with only 25 friends per 'page'!

I can still get my whole friends list using multiple calls, but the game is not currently set up to do that properly. Can anyone tell me why the sudden change? Anyone else seen similar problems and how do I get the list to give me up to 5000 friends per page like it used to.

Reproducible using the Graph API Explorer

Answer 1

In SDK 4.7 you need to pass in a bundle with the number of friends you want to return, I have set it to 5000 as this is the maximum number of friends you can have on Facebook.

You also need to set up your app as a game in the facebook dev console and use invitable friends to get a full friends list

Create your bundle

Bundle bundle = new Bundle();

Add params to your bundle

bundle.putInt("limit", 5000);

Then pass it in to your GraphRequest

new GraphRequest(
            AccessToken.getCurrentAccessToken(),
            "/me/invitable_friends",
            bundle,
            HttpMethod.GET,
            new GraphRequest.Callback() {
                public void onCompleted(GraphResponse response) {
                   //Do something with the response
                }
            }
    ).executeAsync();

I don't know what else to tell you; perhaps the default number returned has changed, but when I try, a call to /me/friends?limit=5000 returns the full list for me (but my friends list is >500 and < 1000 , so maybe it cuts off somewhere along the way)

(Side note: the average number of friends has been found to be ~190 so presumably most users will have less than 500 anyway, and having to page above 500 would be an edge case
