Can you get a current users friendlist with facebook API? [duplicate]

I am trying to get my friend name and ids with Graph API v2.0, but data returns empty:
{
"data": [
]
}
When I was using v1.0, everything was OK with the following request:
FBRequest* friendsRequest = [FBRequest requestForMyFriends];
[friendsRequest startWithCompletionHandler: ^(FBRequestConnection *connection,
NSDictionary* result,
NSError *error) {
NSArray* friends = [result objectForKey:#"data"];
NSLog(#"Found: %i friends", friends.count);
for (NSDictionary<FBGraphUser>* friend in friends) {
NSLog(#"I have a friend named %# with id %#", friend.name, friend.id);
}
}];
But now I cannot get friends!

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.

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.

this.facebookId = jsonObject.getString("id");
this.name = jsonObject.getString("name");
// Handle the picture data.
JSONObject pictureJsonObject = jsonObject.getJSONObject("picture").getJSONObject("data");
boolean isSilhouette = pictureJsonObject.getBoolean("is_silhouette");
if (!isSilhouette) {
this.pictureUrl = pictureJsonObject.getString("url");
} else {
this.pictureUrl = "";
}
this.invitable = true;
} else {
// Parse /me/friends
this.facebookId = jsonObject.getString("id");
this.name = jsonObject.getString("name");
this.available = true;
this.pictureUrl = "";
}
isValid = true;
} catch (JSONException e) {
Log.w("#", "Warnings - unable to process Facebook JSON: " + e.getLocalizedMessage());
}
}
}

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 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.

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<FacebookUser> GetFacebookFriends(string email, string password, int? maxTimeoutInMilliseconds)
{
var users = new List<FacebookUser>();
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 && watch.Elapsed.TotalMilliseconds < maxTimeoutInMilliseconds.Value)
{
var lastLink = browser.Links.Where(l => l.GetAttributeValue("data-hovercard") != null
&& l.GetAttributeValue("data-hovercard").Contains("user.php")
&& 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 => l.GetAttributeValue("data-hovercard") != null
&& l.GetAttributeValue("data-hovercard").Contains("user.php")
&& l.Text != null
).ToList();
var idRegex = new Regex("id=(?<id>([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.

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=

If you are still struggling with this issue on a development mode.
Follow the same process as mentioned below:
create a test app of your main app,
create test users, automatically install app for test users and assign them 'user_friend' permission.
Add your test users as a friend with each other.
I followed the same process after going through alot of research and finally it worked.

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) -> 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;
};
}

Android email client app tracking unread gmail emails

So I've been using javamail API as part of my android app. After a login to a gmail account, the user can write new emails, check the inbox and sent mails. The emails are displayed in a listview with the help of an adapter class. (more accurately the sender, the subject and the sending date is displayed, and if the user clicks on the listview item, then the mail content will be displayed too on a new activity). All this is working well.
I would like to display unread emails differently (unread in the gmail client too), like set the textSyle bold if the mail is unread, but i'm having trouble adding this feature. I've been trying to check the flags of each fetched email message, but for some reason i dont see these flags in the variables.
My code snippet for fetching the mails (display is not here, that's in the adapter class):
protected ArrayList<Email_Message> doInBackground(Void... args) {
try {
Properties properties = new Properties();
properties.put("mail.store.protocol", "imaps");
Session emailSession = Session.getDefaultInstance(properties);
Store store = emailSession.getStore("imaps");
store.connect("imap.gmail.com", username, password);
// create the folder object and open it
Folder emailFolder = store.getFolder("INBOX");
emailFolder.open(Folder.READ_WRITE);
Flags flags2 = emailFolder.getPermanentFlags(); //has 2 weird user flags in it ($phishing, $notphising) and systemflags = -2147483061 ???
Flags seen = new Flags(Flags.Flag.RECENT);
FlagTerm unseenFlagTerm = new FlagTerm(seen, false);
Message messages2[] = emailFolder.search(unseenFlagTerm); //this will net the same result as getMessages(), only here for testing
int test = emailFolder.getUnreadMessageCount(); //as far as i can tell this is working (i have 5000+ emails and 37 them are unread somewhere) but when i get a new email and the number goes up by 1 (38), and if i run the code again, after i already fetched the mails once, it's gonna be 37 again, and the mail marked as read in my gmail webclient too
// retrieve the messages from the folder in an array and print it
Message[] messages = emailFolder.getMessages();
int j = messages.length - 1;
for (int i = j - startIndex; i > j - startIndex - offset && i > (-1); i--) { //startIndex and offset are for displaying only 10 messages at the start and loading another 10 if the user scrolls to bottom
if (isCancelled()){
break;
}
Email_Message mailMessage = new Email_Message(); //my class for storing email messages
mailMessage.messageType = 1;
//some tricks to get the address in the right format
Address[] email_address = messages[i].getFrom();
String tempAddress = email_address[0].toString();
tempAddress = MimeUtility.decodeText(tempAddress);
//still tempering with address, not important
if(tempAddress.contains("=?")){
String[] AddressParts = tempAddress.split("\\?=");
mailMessage.messageAddress = AddressParts[1].substring(2);
}
else {
mailMessage.messageAddress = tempAddress;
}
Flags flags = messages[i].getFlags(); //user_flags = null, system_flags = 32
Flags.Flag[] systemflags = flags.getSystemFlags(); //has 1 item in it: bit = 32
String str[]= flags.getUserFlags(); //empty, these are all true for all my mails, not just one
mailMessage.messageDate = messages[i].getSentDate().toString();
mailMessage.messageSubject = messages[i].getSubject();
Object msgContent = messages[i].getContent();
String content = ""; //getting the content of the mail with these multipart stuffs
if (msgContent instanceof Multipart) {
Multipart multipart = (Multipart) msgContent;
Log.e("BodyPart", "MultiPartCount: " + multipart.getCount());
for (int k = 0; k < multipart.getCount(); k++) {
BodyPart bodyPart = multipart.getBodyPart(k);
String disposition = bodyPart.getDisposition();
if (disposition != null && (disposition.equalsIgnoreCase("ATTACHMENT"))) {
DataHandler handler = bodyPart.getDataHandler();
content = handler.getName();
} else {
content = bodyPart.getContent().toString();
}
}
} else
content = messages[i].getContent().toString();
mailMessage.messageContent = content;
EmailInbox.add(mailMessage);
}
// close the store and folder objects
emailFolder.close(false);
store.close();
} catch (NoSuchProviderException e) {
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
return EmailInbox;
}
I put some comments in the code to explain what i've found in the flags. What can I do to make this work? I already predict problems, like what happens after I read an unread mail in my app only, set its flag to seen, and when I start the activity again and fetch the mails, it's gonna be unread again, since I don't store them locally, but that's a problem after I managed to find a solution for this first.
Thanks for any help!

I'm not clear on how you're looking for the flags. Using messages[i].isSet(Flags.Flag.SEEN) will tell you if the SEEN flag has been set. Note that the SEEN flag will normally be set as soon as you access the content of the message, so you should not have to set it yourself.
Hint: use the InternetAddress.toUnicodeString method, or get the name and address separately using the getPersonal and getAddress methods. This will avoid any need to decode them yourself.

Android - Facebook API giving empty result for user cover photo

I'm trying to get the user's cover photo and show it at the top of a layout. I'm using AsyncTask to run the API call to Facebook. The code I'm using to get the Facebook data is
JSONObject json = null;
response = Utility.facebook.request("me?fields=cover");
json = Util.parseJson(response);
The exception that stops the thread comes from a json error on the next step because the returned json is empty, even though the request clears through. I can get a proper json using just "me" or "me/albums" or anything other than "me?fields=cover". When I comment out the last line, 'try' process finishes with no exceptions/errors.
Is there something wrong with the Facebook API or am I doing something wrong?

I personally prefer using FQL when dealing with User Profile. If you would like to give FQL a try, check the following piece of code. If you would like to stick to Graph API, see this answer: https://stackoverflow.com/a/12434640/450534
try {
String query = "SELECT pic_cover FROM user where uid = " + PUT_THE_USER_ID_HERE;
Bundle param = new Bundle();
param.putString("method", "fql.query");
param.putString("query", query);
String response = Utility.mFacebook.request(param);
JSONArray JAUser = new JSONArray(response);
for (int i = 0; i < JAUser.length(); i++) {
JSONObject JOUser = JAUser.getJSONObject(i);
// COVER PHOTO
if (JOUser.has("pic_cover")) {
String getCover = JOUser.getString("pic_cover");
if (getCover.equals("null")) {
String finalCover = null;
} else {
JSONObject JOCoverSource = JOUser.optJSONObject("pic_cover");
if (JOCoverSource.has("source")) {
String finalCover = JOCoverSource.getString("source");
} else {
String finalCover = null;
}
}
} else {
String finalCover = null;
}
}
} catch (Exception e) {
// TODO: handle exception
}
The above code already accounts for User's who do not have a Cover Photo set in their profiles and checks for its availability. With this code, you will have the URL to the Cover Photo and can then process it as you prefer.
NOTE: If you are fetching the logged in users cover photo, this piece of code SELECT pic_cover FROM user where uid = " + PUT_THE_USER_ID_HERE; can also be written as: SELECT pic_cover FROM user where uid = me()"; For the non-logged in user's cover photo, the above can be used as is.
Couple of things as a side note.
I use Fedor's Lazy Loading technique to load images in almost exclusively.
I recommend running the code block, mine or any other solution you choose, in an AsyncTask.

The reason for not getting any result can be found in the javadoc of request(String graphPath) method:
(...) this method blocks waiting for a network response, so do not
call it in a UI thread.
In your case, you should probably do the following synchronous call:
Bundle params = new Bundle();
params.putString("fields", "cover");
String result = Utility.facebook.request("me/", params);
Siddharth Lele is very correct in his answer, but I wanted to specify the actual reason for not getting any response in this case.

Note: Fetching Cover Photo using Facebook API and endpoint https://graph.facebook.com/me?fields=cover no longer works as on 20th Dec 2014.
It was supposed to give following response:
{
"cover": {
"cover_id": "10151008748223553",
"source": "http://sphotos-a.ak.fbcdn.net/hphotos-ak-ash4/s720x720/391237_10151008748223553_422785532_n.jpg",
"offset_y": 0
},
"id": "19292868552"
}
But now it just gives User's id:
{
"id": "19292868552"
}
Verified this using Graph Tool explorer v2.2 using me?fields=cover.

"facebook cannot be resolved or is not a field " error in getting facebook userid

here i am trying to get the id of user login with facebook details in to my app
and in the following code i am getting "facebook can not be resolved or not a field error
try {
// PROFILE DETAILS AND FRIENDS COUNTER
String queryUserInfo = "SELECT uid FROM user WHERE uid = me()";
Bundle paramUserInfo = new Bundle();
paramUserInfo.putString("method", "fql.query");
paramUserInfo.putString("query", queryUserInfo);
String responseUserInfo = Util.facebook.request(paramUserInfo);
//"facebook cannot be resolved or is not a field " error in getting facebook userid.
JSONArray JAUserData = new JSONArray(responseUserInfo);
for (int i = 0; i < JAUserData.length(); i++) {
JSONObject JOUserData = JAUserData.getJSONObject(i);
if (JOUserData.has("uid")) {
String getUserID = JOUserData.getString("uid");
}
}
} catch (Exception e) {
e.printStackTrace();
}

Don't like fql, but i think this:
you can't add parameter method as fql-query
you must add subpath /fql
you must NOT USE fql for such simple things (https://graph.facebook.com/me will help)
After all:
You need to create a request with subpath /fql and with only one parameter: q=YOURQUERY
Example: https://graph.facebook.com/fql?q=YOUREQUEST&access_token=ACCESS_TOKEN
Advise: use Graph-API instead, it is very simple.
How to begin: It is Graph Api
And you can find Tools for facebook Api (i recommend Graph API Explorer)

facebook sdk android wall post line break

I'm making an application that is posting some information to your facebook wall using facebook sdk for android. This works, but I can't seem to get new lines on the posts. I have tried \n but it doesent work. Any suggestions?
Here is my code:
Bundle parameters = new Bundle();
String temp = "";
for (int i = 0; i < mArrayAdapter.getCount(); i++){
temp = temp + mArrayAdapter.getItem(i) + "\n"; // Not working
}
parameters.putString("message", temp);
mFacebook.dialog(this, "stream.publish", parameters, new DialogListener());
Thanks,
James Ford

Hi James i have tried that before, even with html code but i think thats not possible.
The reason, Facebook must have a control to avoid blank spaces or line break on his posts.

New lines are not allowed in stream posts (the fact that you may have seen them in the past are bugs on facebook).

make use of JSON to post on facebook..
how? look here
STEPS :-
Step 1 :- At this link u will came to know how to use JSON for setting text to TEXTVIEW.
Step 2 :- May be this is not u r looking for :) assign the text of textview to some string
using GetText().ToString
Step 3 :- use this string to post to the facebook.
Step 4 :- I did the same after spending lot of time in googling and finally got the result
by using this trick. u can see my post that i posted during test here
Step 5 :- set the visibilty of this text box to gone using
tv.setVisibility(View.GONE)
And u r done with your posting to facebook..
let the facebook and textview handle how they manage spaces and new line character :D
Some Coding work for newbies like me...
I am posting it on click of button
1)
tv= (TextView)findViewById(R.id.tv);
click=(Button)findViewById(R.id.btn1);
click.setOnClickListener(mthdpost);
2) add on click event to this button
private View.OnClickListener mthdpost=new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
String json = "{"
+ " \"name\": \"myName\", "
+ " \"message\": [\"myMessage1\",\"myMessage2\"],"
+ " \"place\": \"myPlace\", "
+ " \"date\": \"thisDate\" "
+ "}";
/* Create a JSON object and parse the required values */
JSONObject object = (JSONObject) new JSONTokener(json).nextValue();
String name = object.getString("name");
String place = object.getString("place");
String date = object.getString("date");
JSONArray message = object.getJSONArray("message");
String MessageToPost= null;
tv.setText("Name: "+ name +"\n\n");
tv.append("Place: "+ place +"\n\n");
tv.append("Date: "+ date +"\n\n");
/*JSONObject attachment = new JSONObject();
attachment.put("Name: ","\n\n");
attachment.put("Place: ","\n\n");
attachment.put("Date: ","\n\n");*/
for(int i=0;i<message.length();i++)
{
tv.append("Message: "+ message.getString(i) +"\n\n");
//attachment.put("Message: ","\n\n");
}
MessageToPost=tv.getText().toString();
postToWall(MessageToPost);// called the method having logic to post on wall and sending the textview text to to post as message
} catch (JSONException e)
{e.printStackTrace();
}
catch(Exception ex)
{ex.printStackTrace();}
}
};
3) method for posting the message
public void postToWall(String msg){
Log.d("Tests", "Testing graph API wall post");
try {
String response = facebook.request("me");
Bundle parameters = new Bundle();
//parameters.putString("message", msg.toString());
parameters.putString("message", msg);
parameters.putString("description", "test test test");
response = facebook.request("me/feed", parameters,
"POST");
Log.d("Tests", "got response: " + response);
if (response == null || response.equals("") ||
response.equals("false")) {
Log.v("Error", "Blank response");
}
} catch(Exception e) {
e.printStackTrace();
}
}
HOPE IT WILL HELP :)

This worked for me:
StringBuilder messageData = new StringBuilder(title).append('\n')
.append('\n').append(message).append('\n').append('\n')
.append(description);
// Message
postParams.putString("message", messageData.toString());

This works:
Use this: <center></center>
Instead of a br or a newline, etc. You can only do one in a row (ie. you can't increase the spacing).
