Unity Facebook SDK: FB.Feed not posting

Question

I finished my game. Now I want to make it social. Posting to twitter is easy, but I have a problem with facebook.

I created an app on facebook dev, I have key-hash, key-store, I don't have any errors in console. I made enviroment variables with paths to JDK and OpenSSL. Maybe there's something wrong with my code (it's from SDK example) but I don't know what.

This script is attached to NGUI button. In editor it works but on device it only asks to login and permission. Then nothing happens.

using UnityEngine;
using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;

public sealed class FacebookShare : MonoBehaviour {
#region FB.Init() example

private bool isInit = false;

void Awake ()
{
    CallFBInit();
}

private void CallFBInit()
{
    FB.Init(OnInitComplete, OnHideUnity);
}

private void OnInitComplete()
{
    Debug.Log("FB.Init completed: Is user logged in? " + FB.IsLoggedIn);
    isInit = true;
}

private void OnHideUnity(bool isGameShown)
{
    Debug.Log("Is game showing? " + isGameShown);
}

        lastResponse = "Error Response:\n" + result.Error;

You trying to feed before LoginCallback called. Try to change your LoginCallback and OnClick functions something like this:

   void LoginCallback(FBResult result) {
        if (result.Error != null)
            lastResponse = "Error Response:\n" + result.Error;
        else if (!FB.IsLoggedIn)
        {
            lastResponse = "Login cancelled by Player";
        }
        else
        {
            lastResponse = "Login was successful!";
            CallFBFeed();
        }
    }
    void OnClick ()
    {
       CallFBLogin();
    }
