将此代码用于facebook 2.x sdk此sdk已弃用，这就是错误显示的原因。尝试使用facebook 3.x sdk

NOTE:至于你的要求这是一次尝试这个

 private void SendRequest() {

    try {
        String response = facebook.request("me");
        Bundle parameters = new Bundle();
        parameters.putString("message", "contentStr");
        parameters.putString("description", "data");
        parameters.putString("name", "name");
        parameters.putString("picture","http://twitpic.com/show/thumb/6hqd44");
        parameters.putString("link", "http://www.londatiga.net");
        response = facebook.request("me/feed", parameters, "POST");
        Log.d("Tests", "got response: " + response);
        if (response == null || response.equals("")
                || response.equals("false")) {
            Log.i("TAG", "Blank Response...");
        } else {

        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}
