How to get online friends?

[ADietrich]

The request to get all friends of my facebook account works fine:
mAsyncRunner.request("me/friends", new SampleRequestListener());

And the request to get informations about one friend works fine too:
mAsyncRunner.request(userID, new SampleRequestListener());

But how do I get the information about which of my friends are currently online?
I know that I can specify parameters for the bundle by means of filtering, but I have not found a parameter that filters the list of friends after their online status.

My internet research revealed the parameter "online_presence = active", but it had no effect. One of the friends was clearly not online during the test and stood still in the list.

Is there somewhere a list of possible parameters for various requests, such as just a list of currently active friends.

This is a general API question, not specific to Android, so try asking on the developer forum: http://forum.developers.facebook.com/ -- let me know if you don't get an answer there -- I can look into it, but I think it will be more useful to anyone with the same query to have it answered on the forum.
