How post message on facebook without open any dialog?

Question

I want to post messages on facebook without open dialog using native Facebook android app. I am using facebook sdk 3.5.2. I have successfully post messages on wall.

I am facing some problems.

1) if I logout from native Facebook app. Then it post messages to previous user's Facebook wall & it not ask for authentication.

2)If user login with different account in Facebook native app, it still post messages to previous account( which login first time through app). Not ask for authentication.

Code:-

 Session.openActiveSession(this, true, new Session.StatusCallback() {

                // callback when session changes state
                @Override
                public void call(Session session, SessionState state, Exception exception) {
                    if (session.isOpened()) {

                        new messagePostAsyn().execute(session);

                    }
                }
              });

Method:

 private void postStatus(final Session session, String message) {


    Bundle _postParameter = new Bundle();
    _postParameter.putString("name", message);

    _postParameter.putByteArray("picture", bytes);
    _postParameter.putString("caption", "To help....");
    _postParameter.putString("description", "Testing...");
    Request request = new Request(session, "me/photos", _postParameter,
            HttpMethod.POST, new Callback() {

                @Override
                public void onCompleted(Response response) {
                    // TODO Auto-generated method stub
                    System.out.println("response......" + response);

                }
            });



    Request.executeBatchAsync(request);


}

This method used in messagePostAsyn() class.

Try this Code :

public void postToWall(String message) {
    Bundle params = new Bundle();
    params.putString("message", message);

    // Uses the Facebook Graph API
    try {
        facebook.request("/me/feed", params, "POST");
        this.finish();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}
