I'm using this facebook sdk - https://github.com/facebook/facebook-android-sdk/

Here is my code to posting message on wall:

 private static void postOnWall(String msg) {
            Log.d(LOGTAG, "Testing graph API wall post");
             try {
                 //   String response = facebook.request("me");
                    Bundle parameters = new Bundle();
                    parameters.putString("message", msg);
                    parameters.putString("description", "test test test");
                    String response = facebook.request("me/feed", parameters, 
                            "POST");
                    Log.d(LOGTAG, "got response: " + response);
                    if (response == null || response.equals("") || 
                            response.equals("false")) {
                       Log.v(LOGTAG, " error Blank response");
                    }
             } catch(Exception e) {
                 e.printStackTrace();
             }
        }

Answer 1

There are three reasons that you would get this exception:

1. You have not declared the internet permission in your manifest
2. The device does not have an internet connection, or has one which blocks facebook access at the DNS level. Try using a home network if you're behind a company porxy.
3. Facebook's server's are temporarily not working.

Answer 2

i get

got response: {"error":{"message":"An active access token must be used to query information about the current user.","type":"OAuthException","code":2500}}
