- FQL is deprecated, you really should not use it anymore. Also, you can only get a list of friends who authorized your App too. See this thread for more information: Get ALL User Friends Using Facebook Graph API - Android
- No, you can´t get the list of places your friends visited, for obvious privacy reasons.
Edit: As i can still see your deleted answer (which should have been a comment to my answer instead, i guess): To make this perfectly clear, you can NOT get all friends anymore. Again, check out the link i posted, all you need to know is in the accepted answer over there. And no, you can NOT get the list of places of your friends, just because they are available on Facebook for you. That does not mean an App can get them. About the dev group on Facebook: Try several times, and hopefully you are not trying with a fake account ;)
