Facebook has revised their policies now  You can   t get the whole friendlist anyway if your app does not have a Canvas implementation and if your app is not a game  Of course there   s also taggable friends  but that one is for tagging only   You will be able to pull the list of friends who have authorised the app only   The apps that are using Graph API 1 0 will be working till April 30th  2015 and after that it will be deprecated   See the following to get more details on this    User Friends Facebook Application Development FAQ

In the Facebook SDK Graph API v2 0 or above  you must request the user friends permission from each user in the time of Facebook login since user friends is no longer included by default in every login  we have to add that   Each user must grant the user friends permission in order to appear in the response to  me friends   let fbLoginManager   FBSDKLoginManager   FBSDKLoginManager   fbLoginManager loginBehavior   FBSDKLoginBehavior web fbLoginManager logIn withReadPermissions    email   user friends   public profile    from  self     result  error  in     if  error    nil             let fbloginresult   FBSDKLoginManagerLoginResult   result          if fbloginresult grantedPermissions    nil               if  fbloginresult grantedPermissions contains  email                         Do the stuff                           else                                   else                       So at the time of Facebook login  it prompts with a  screen which contain all the permissions     If the user presses the Continue button  the permissions will be set  When you access the friends list using Graph API  your friends who logged into the application as above will be listed  if   FBSDKAccessToken current       nil        FBSDKGraphRequest graphPath    me friends   parameters    fields     id name    start completionHandler     connection  result  error  - gt  Void in         if  error    nil                 print result                        The output will contain the users who granted the user friends permission at the time of login to your application through Facebook         data                                     id   xxxxxxxxxx                   name    xxxxxxxx                                    paging             cursors                 after   xxxxxx              before   xxxxxxx                        summary              total count    8

As Simon mentioned  this is not possible in the new Facebook API  Pure technically speaking you can do it via browser automation    this is against Facebook policy  so depending on the country where you live  this may not be legal you ll have to use your credentials   ask user for credentials and possibly store them  storing passwords even symmetrically encrypted is not a good idea  when Facebook changes their API  you ll have to update the browser automation code as well  if you can t force updates of your application  you should put browser automation piece out as a webservice  this is bypassing the OAuth concept on the other hand  my feeling is that I m owning my data including the list of my friends and Facebook shouldn t restrict me from accessing those via the API   Sample implementation using WatiN   class FacebookUser     public string Name   get  set      public long Id   get  set       public IList lt FacebookUser gt  GetFacebookFriends string email  string password  int  maxTimeoutInMilliseconds      var users   new List lt FacebookUser gt       Settings Instance MakeNewIeInstanceVisible   false    using  var browser   new IE  https   www facebook com            try             browser TextField Find ByName  email    Value   email        browser TextField Find ByName  pass    Value   password        browser Form Find ById  login form    Submit          browser WaitForComplete              catch  ElementNotFoundException                 We re already logged in           browser GoTo  https   www facebook com friends        var watch   new Stopwatch        watch Start         Link previousLastLink   null      while  maxTimeoutInMilliseconds HasValue  amp  amp  watch Elapsed TotalMilliseconds  lt  maxTimeoutInMilliseconds Value              var lastLink   browser Links Where l   gt  l GetAttributeValue  data-hovercard      null                         amp  amp  l GetAttributeValue  data-hovercard   Contains  user php                           amp  amp  l Text    null                        LastOrDefault           if  lastLink    null    previousLastLink    lastLink                  break                 var ieElement   lastLink NativeElement as IEElement        if  ieElement    null                  var htmlElement   ieElement AsHtmlElement          htmlElement scrollIntoView            browser WaitForComplete                   previousLastLink   lastLink             var links   browser Links Where l   gt  l GetAttributeValue  data-hovercard      null        amp  amp  l GetAttributeValue  data-hovercard   Contains  user php          amp  amp  l Text    null       ToList         var idRegex   new Regex  id    lt id gt   0-9            foreach  var link in links              string hovercard   link GetAttributeValue  data-hovercard          var match   idRegex Match hovercard         long id   0        if  match Success                  id   long Parse match Groups  id   Value                 users Add new FacebookUser                 Name   link Text          Id   id                       return users      Prototype with implementation of this approach  using C  WatiN  see https   github com svejdo1 ShadowApi  It is also allowing dynamic update of Facebook connector that is retrieving a list of your contacts

In v2 0 of the Graph API  calling  me friends returns the person s friends who also use the app   In addition  in v2 0  you must request the user friends permission from each user  user friends is no longer included by default in every login  Each user must grant the user friends permission in order to appear in the response to  me friends  See the Facebook upgrade guide for more detailed information  or review the summary below   If you want to access a list of non-app-using friends  there are two options    If you want to let your people tag their friends in stories that they publish to Facebook using your App  you can use the  me taggable friends API  Use of this endpoint requires review by Facebook and should only be used for the case where you re rendering a list of friends in order to let the user tag them in a post  If your App is a Game AND your Game supports Facebook Canvas  you can use the  me invitable friends endpoint in order to render a custom invite dialog  then pass the tokens returned by this API to the standard Requests Dialog    In other cases  apps are no longer able to retrieve the full list of a user s friends  only those friends who have specifically authorized your app using the user friends permission   This has been confirmed by Facebook as  by design    For apps wanting allow people to invite friends to use an app  you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android   UPDATE  Facebook have published an FAQ on these changes here  https   developers facebook com docs apps faq which explain all the options available to developers in order to invite friends etc

In Swift 4 2 and Xcode 10 1   If you want to get the friends list from Facebook  you need to submit your app for review in Facebook  See some of the Login Permissions   Login Permissions  Here are the two steps   1  First your app status is must be in Live    2  Get required permissions form Facebook   1  Enable our app status live    Go to the apps page and select your app  https   developers facebook com apps  Select status in the top right in Dashboard    Submit privacy policy URL   Select category   Now our app is in Live status      One step is completed   2  Submit our app for review    First send required requests    Example  user friends  user videos  user posts  etc    Second  go to the Current Request page    Example  user events Submit all details    Like this submit for all requests  user friends   user events  user videos  user posts  etc    Finally submit your app for review   If your review is accepted from Facebook s side  you are now eligible to read contacts  etc

Although Simon Cross s answer is accepted and correct  I thought I would beef it up a bit with an example  Android  of what needs to be done  I ll keep it as general as I can and focus on just the question  Personally I wound up storing things in a database so the loading was smooth  but that requires a CursorAdapter and ContentProvider which is a bit out of scope here   I came here myself and then thought  now what    The Issue  Just like user3594351  I was noticing the friend data was blank  I found this out by using the FriendPickerFragment  What worked three months ago  no longer works  Even Facebook s examples broke  So my issue was  How Do I create FriendPickerFragment by hand   What Did Not Work  Option  1 from Simon Cross was not strong enough to invite friends to the app  Simon Cross also recommended the Requests Dialog  but that would only allow five requests at a time  The requests dialog also showed the same friends during any given Facebook logged in session  Not useful   What Worked  Summary   Option  2 with some hard work  You must make sure you fulfill Facebook s new rules  1   You re a game 2   You have a Canvas app  Web Presence  3   Your app is registered with Facebook  It is all done on the Facebook developer website under Settings   To emulate the friend picker by hand inside my app I did the following    Create a tab activity that shows two fragments  Each fragment shows a list  One fragment for available friend   me friends  and another for invitable friends   me invitable friends   Use the same fragment code to render both tabs  Create an AsyncTask that will get the friend data from Facebook  Once that data is loaded  toss it to the adapter which will render the values to the screen    Details  The AsynchTask  private class

Try  me taggable friends limit 5000 using your JavaScript code  Or  try the Graph API   https   graph facebook com v2 3 user id here taggable friends access token

[facebook] Facebook Graph API v2.0+ - /me/friends returns empty, or only friends who also use my application
