java - Android Facebook 图谱 API

Question

有人有关于如何使用 Android Graph API 的示例吗？

我受困于基础知识，例如在 Facebook 上将文本发布到墙上。

我正在使用适用于 Android 的 Facebook SDK。这是我目前所拥有的:

    Bundle params = new Bundle();
    params.putString("message", "picture caption");

    AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
    mAsyncRunner.request("me/feed", params, "POST", new RequestListener() {

        @Override
        public void onMalformedURLException(MalformedURLException e, Object state) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onIOException(IOException e, Object state) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onFileNotFoundException(FileNotFoundException e, Object state) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onFacebookError(FacebookError e, Object state) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onComplete(String response, Object state) {
            // TODO Auto-generated method stub

        }
    }, "foo");

没有任何反应，我的 Logcat 说:

Answer 1

试试这个

Bundle params = new Bundle();
params.putString(Facebook.TOKEN, token);   
params.putString("message", "graph api");       
mAsyncRunner.request("/me/feed", params,"POST", new SampleUploadListener(),null);

你可以通过使用获取访问 token

      token = mFacebook.getAccessToken();
