Как поделиться ссылкой на ссылку на Facebook без установки приложения?

Question

Я использую sdk из facebook, чтобы поделиться ссылкой на приложение. Когда у меня есть приложение facebook, установленное на моем устройстве, оно отлично работает. Но я хочу, чтобы пользователь мог поделиться им, не установив приложение на устройство. Ссылка на учебник от Facebook, чтобы сделать это сломана, и я получаю этот пример подачи Диалога в интернете:

private void publishFeedDialog() { 
    Session session = Session.getActiveSession(); 
    Bundle params = new Bundle(); 

    params.putString("name", "***"); 
    params.putString("caption", "***");//caption 
    params.putString("picture", ***"); 
    params.putString("link", "***"); 

    Request.Callback callback = new Request.Callback() { 
     public void onCompleted(Response response) {   
      FacebookRequestError error = response.getError(); 
      if (error != null) { 
       Log.i("Tag", "FacebookRequestError" + error.getErrorMessage()); 
       Toast.makeText(CompartilhamentoActivity.this, error.getErrorMessage(), Toast.LENGTH_SHORT).show(); 
      } else { 
       Log.i("Tag", "FacebookRequest Done"); 
       Toast.makeText(CompartilhamentoActivity.this, "Story Published to Your Wall", Toast.LENGTH_LONG).show(); 
      } 
     } 
    }; 

    Request request = new Request(session, "me/feed", params, HttpMethod.POST, callback); 
    RequestAsyncTask task = new RequestAsyncTask(request); 
    task.execute(); 
} 

Когда я использую этот метод, я получаю эту ошибку «FacebookRequestErrorcom.facebook.FacebookException: Session условие на запрос в незакрытом состоянии ».
