Facebook unity sdk avoid showing You have already authorised this app

Question

How can I avoid showing You have already authorised this app using Facebook Unity SDK. Calling FB.Login(string.Empty, LoginCallback) function with empty string still calls basic authorisation.

Answer 1

Hi try to call this method which will avoid the Basic Authorization for fb...

    private void loginWithFB()
{

    //final Dialog d = ProgressDialog.showDialog((Activity)mContext, "Please Wait...");

     Log.d(TAG, "inside loginToFB");
     String GCM_ID = registraionID;
     Log.d(TAG, "inside loginToFB got gcm id :"+GCM_ID);
    SessionTracker mSessionTracker = new SessionTracker(getBaseContext(), new StatusCallback() 
    {

        @Override
        public void call(Session session, SessionState state, Exception exception) 
        {
            Log.d(TAG, "loginToFB call");
        }
    }, null, false);

    //String applicationId = Utility.getMetadataApplicationId(getBaseContext());


    String applicationId = TagStrings.APP_ID;
    Log.d("Fb Login ID..", applicationId+"");
    Session mCurrentSession = mSessionTracker.getSession();
    Log.d(TAG, "loginToFB got currentsession");
    if (mCurrentSession == null || mCurrentSession.getState().isClosed()) 
    {
        Log.d(TAG, "loginToFB curent session is bad creating new one");
        mSessionTracker.setSession(null);
        Session session = new Session.Builder(getBaseContext()).setApplicationId(applicationId).build();
        Session.setActiveSession(session);
        mCurrentSession = session;
    }

    final Session mCurrentSessionFin = mCurrentSession;

    if (!mCurrentSession.isOpened()) 
    {
        Log.d(TAG, "loginToFB current session is closed");
        Session.OpenRequest openRequest = null;
        openRequest = new Session.OpenRequest(LoginActivity.this);

        Log.d(TAG, "loginToFB session open req sent");
        if (openRequest != null) 
        {
            //openRequest.setDefaultAudience(SessionDefaultAudience.FRIENDS);
            openRequest.setPermissions(Arrays.asList("user_birthday", "email", "user_location"));
            openRequest.setLoginBehavior(SessionLoginBehavior.SSO_WITH_FALLBACK);
