Facebook FriendPickerFragment api

Question

I have downloaded facebook-android-sdk-3.14.1.zip and am trying to get the examples working. I get stuck on the FriendPickerFragment that never returns a list of friends. I can log onto Facebook ok (again using the Facebook code), both using the 'Scrumptious' example and my version of it by followiing https://developers.facebook.com/docs/android/getting-started

I found that my requests were only going with public profile permission e.g.

{Session state:OPENED, token:{AccessToken token:ACCESS_TOKEN_REMOVED permissions:[public_profile]}, appId:520510648055719}

I took code from Facebook friend picker SDK sample not working Android, that would add the user_friends permission and see that Session was now:

{Session state:OPENED, token:{AccessToken token:ACCESS_TOKEN_REMOVED permissions:[public_profile, basic_info, user_friends]}, appId:520510648055719}

When I traced the code down to RequestAsyncTask.doInBackground the values of requests in :

@Override
protected List<Response> doInBackground(Void... params) {
    try {
        if (connection == null) {
            return requests.executeAndWait();
        } else {
            return Request.executeConnectionAndWait(connection, requests);
        }
    } catch (Exception e) {
        exception = e;
        return null;
    }
}

is

{Request:  session: {Session state:OPENED, token:{AccessToken    token:ACCESS_TOKEN_REMOVED permissions:[public_profile, basic_info, user_friends]}, appId:520510648055719}, graphPath: me/friends, graphObject: null, restMethod: null, httpMethod: GET, parameters: Bundle[{fields=id,name,picture.height(75).width(75)}]}

and I see as a response in onPostExecute(List result) :

 [{Response:  responseCode: 200, graphObject: GraphObject{graphObjectClass=GraphObject, state={"data":[]}}, error: null, isFromCache:true}]

Could there have been some caching problem earlier that I need to clear first? If so how do I do that?

I have read that Facebook has changed security recently. I have create my Facebook TestUI 'app' and entered the hashKey (I assume all is ok as I can log into Facebook successfully)

Is there something else I should be looking at?

Looking for any and all wisdom on this.

Thanks

Please search on stackoverflow. You are most likely using API v2.0 which means that you will only get back friends that are also using the app — WizKid, May 21 '14 at 22:11

With Graph Search v2.0, requests for a user's friends will only return a list of friends that also use your app (including the samples), and the user_friends permission must be requested as a special permission. There doesn't appear to be a true way around this, though you can search for things like "taggable_friends" using something like:

    new Request(
    session,
    "/me/taggable_friends", //instead of "/me/friends"
    null,
    HttpMethod.GET,
    new Request.Callback() {
        public void onCompleted(Response response) {
            /* handle the result */
        }
    }).executeAsync();

from Facebook Graph Reference.

My app records distance covered during and exercise (walking, hiking, biking, etc.) with some statistics. I wanted the app to post the stats to the persons timeline and have friends see it. As I understand your and Whizkid's comments, I will only get a list of friends that also have the app. Is that correct? – Eric May 22 '14 at 12:18
That is correct. You can, however, search for "taggable_friends," and that should return a list of friends that allow you to tag them in status (at least in theory, Facebook generates unreliable documentation that goes out of date very quickly). – MarmotXing May 22 '14 at 14:06
