Question

In my project I authenticate my Facebook account in the first activity and retrieved the friends id,name, birthday and pic, who is having birthday on the current day. I bundled them to the next activity and displayed the pic and name in listview. I want to post some message to their wall, when I click on the list. I used the following code to post on friends wall while click on the listview.

  public static String APP_ID = "my_app_id";
        public static Facebook authenticatedFacebook = new Facebook(APP_ID);

In my listview onclickitemlistner I used the following code. id_list is an ArrayList contains the ids of the friends.

try{
                        Bundle parameters = new Bundle();
                        JSONObject attachment = new JSONObject();

                        try {
                            attachment.put("message", "Many more returns of the day");


                        } catch (JSONException e) {
                        }
                        parameters.putString("attachment", attachment.toString());

                        parameters.putString("target_id", id_list.get(position)); 
                        parameters.putString("method", "stream.publish");
                        String  response = authenticatedFacebook.request(parameters);       
                        Log.v("response", response);
                    }
                    catch(Exception e){}

In my response I got invalid API key. But I used the correct key.

11-10 16:21:53.987: V/response(396): {"error_code":101,"error_msg":"Invalid API key","request_args":[{"key":"method","value":"stream.publish"},{"key":"attachment","value":"{\"message\":\"Many more returns of the day\"}"},{"key":"format","value":"json"},{"key":"target_id","value":"100000635832872"}]}

I used the same code to post using the retrieved id of the friend in my first activity where I authenticate my account. It works fine. But not works in the second activity where I display them in listview. I checked whether the session is valid or not. It results in invalid.

I got it work. Just change the Facebook.java class. Changed DEFAULT_AUTH_ACTIVITY_CODE to FORCE_DIALOG_AUTH. And check for Facebook session. It works fine with my code.
