I implemented Facebook Sharing dialog using basic FB.SharLink and FB.FeedShare in one a sample project. Now when I create a new Facebook Application for Live project and Integrated into My Live Unity Project, It stopped working as it is designed.

Steps : Create Facebook Application , Added Android product in it. Disabled the development mode and all other necessary basic setting about application info such as namespace, app domain & Website.

Issue : When I go for post to Facebook, it clears out title and description of written by my C# code and get some title and description from the website link, if it founds nothing from website , it sets website URL text as Content Title and Content Description.

Tweak : Now when I app App Id and App Name from Sample project to Live project and change Bundle Identifier Name and set it to sample project's bundle identifier name and then when I build my live project and test it and It worked actually. Now I am amazed how this could be happen ?

I am providing the same link such as www.google.com. It is working in Old Sample Project with it's Facebook application , but it is not working for live project and new Facebook Application.

Then I went to developers.facebook.com and check all the setting of both Facebook application. But all settings are same. Not a penny is different except from Facebook Application Id, Name & Secret Key.

Please help me on this.

using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using UnityEngine;
using Facebook.Unity;
using Facebook.Unity.Example;
using UnityEngine.UI;


public class FBShareScreenShotTest : MonoBehaviour {

    public void ShareScreenShot(){
        Debug.Log ("SHARE");
        //ShareScoreOnFB();
        FB.ShareLink(
            new Uri("URL where you want to redirect the user"),
            "Rebisco",
            "Lets have a great adventure.",
            new Uri("Image here URL "),
            callback: ShareCallback);
    }


    private void ShareCallback (IShareResult result) {
        if (result.Cancelled || !String.IsNullOrEmpty(result.Error)) {
            Debug.Log("ShareLink Error: "+result.Error);
        } else if (!String.IsNullOrEmpty(result.PostId)) {
            // Print post identifier of the shared content
            Debug.Log(result.PostId);
        } else {
            // Share succeeded without postID
            Debug.Log("ShareLink success!");

        }
    }

}

  • I tried to the same using using your code but problem is still not resolved. I have this scenario I have 2 Facebook application A and B. A is old one. I create new Facebook app named B Facebook developer account. All basic settings are same. Now when I compile and build android apk with A Application it works. I got desired title in my post. But when I just change App id to B from A in Facebook Setting in inspector menu and then make a new android build. What I got it sharing is done. But instead of "Rebisco" as title. Same issue with description. I hope you undesrtand my issue. – Sarthak Shah Apr 26 '17 at 08:24

  • I got your project and and make android build and I didn't got desirable Title and description. I think as per code Title should be "Rebisco" and Description should be "Lets have a great adventure". But when I build I found different sharing dialog. Have a look at here [link](http://facebookshare.azurewebsites.net/Images/FbShare.jpeg) . – Sarthak Shah Apr 28 '17 at 05:21
  • I see.... what happen when you post it.... and may i know the speed of your internet... and android version of your phone.... you can test your speed here... speedtest.net... cheers – Tony Apr 28 '17 at 05:30
  • Did you change the APP ID and Copy the info below Android Build Facebook Setting to your Facebook APP in https://developers.facebook.com/ ... You can access the Facebook Menu by Going to Menu - > Facebook -> Edit Setting .... Cheers... – Tony Apr 28 '17 at 05:50
  • I am having internet download speed 36.64 mbps upload speed 35.06 mbps. I tried the app by putting my app id and bundle identifier as in my facebook setting page, But no luck. The Same Sharing dialog appears as I send you link in my above message. – Sarthak Shah Apr 28 '17 at 06:25
  • I see... how about the phone that you use... what is the android version and did you try to use another phone... – Tony Apr 28 '17 at 10:15
