facebook login callback fires multiple times

Question

My app is having Share button to share story on users timeline. What I\'m doing is, user taps on Share button, if user session is not present app forces to Logi

Answer 1

remove all the publishStory() calling. in your callback do this:

public void call(Session session, SessionState state,
        Exception exception) {
    if(session != null && session.isOpened() && isShared){
       publishStory();
    }
}

in your UpdateDetails class declare isShared as boolean isShared = false; and when user tap on share button make it true, like:

shareBtn.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View arg0) {
        isShared = true;
        doPostStory();                              
    }
});

in your publishStorys onComplete make isShared false. like:

public void onCompleted(Response response) {
    isShared = false;
    ...................
    ...................
}

hope this will help.

Create Facebook Session Object
Then Just Apply This in onCreate Method.

 Session.openActiveSession(this, true, new Session.StatusCallback() {

        // callback when session changes state
        @Override
        public void call(Session session, SessionState state,
                Exception exception) {
            if (session.isOpened()) {

                // make request to the /me API
                Request.newMeRequest(session,
                        new Request.GraphUserCallback() {

                            // callback after Graph API response with user
                            // object
                            @Override
                            public void onCompleted(GraphUser user,
                                    Response response) {
                                FacebookLoginActivity.this.progressDialog = ProgressDialog
                                        .show(YourActivity.this,
                                                "",
                                                "",
                                                true);
                                if (user != null) {

                                   Intent passIntent = new Intent(YourActivity.this,Second.class)
                                   startActivity(passIntent)
                                }
                            }
                        }).executeAsync();

            }
        }
    });
