Android 将图片发布到 Facebook 墙

我正在尝试将照片发布到我的 Facebook 墙上。我已经成功登录并将文本发布到墙上。然而，当我尝试发布图片时，什么也没有发生。

我正在使用Android 脸书 SDK.

这是我到目前为止所拥有的：

    Bundle params = new Bundle();
    params.putString("method", "photos.upload");

    Toast.makeText(FacebookPoster.this, "" + getIntent().getExtras().getByteArray("data").length, Toast.LENGTH_SHORT).show();

    params.putByteArray("picture", getIntent().getExtras().getByteArray("data"));

    AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
    mAsyncRunner.request(null, params, "POST", new SampleUploadListener(), null);

Toast显示8733，这意味着字节数组不为空

注意。 Logcat 输出一些警告（不是错误）：

03-02 14:19:29.554: WARN/Bundle(1891): Attempt to cast generated internal exception:

我究竟做错了什么？

SOLVED.这就是我为使其发挥作用所做的：

facebook.authorize(this, new String[] { "publish_stream" },
        new DialogListener() {

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

    @Override
    public void onError(DialogError dialogError) {
    // TODO Auto-generated method stub
    }

    @Override
    public void onComplete(Bundle values) {
        postToWall(values.getString(Facebook.TOKEN));                                              
    }

    @Override
    public void onCancel() {
    // TODO Auto-generated method stub
    }
});

以及辅助方法：

private void postToWall(String accessToken) {       
    Bundle params = new Bundle();

    params.putString(Facebook.TOKEN, accessToken);

    // The byte array is the data of a picture.
    params.putByteArray("picture", getIntent().getExtras().getByteArray("data"));

    try {
        facebook.request("me/photos", params, "POST");

    } catch (FileNotFoundException fileNotFoundException) {
        makeToast(fileNotFoundException.getMessage());
    } catch (MalformedURLException malformedURLException) {
        makeToast(malformedURLException.getMessage());
    } catch (IOException ioException) {
        makeToast(ioException.getMessage());
    }
}

首先，你没有使用 graph api 来上传图片...你正在使用旧的 Rest api...尝试使用 graph api，它很简单...

使用以下代码：

Bundle param = new Bundle();
param.putString("message", "picture caption");
param.putByteArray("picture", ImageBytes);
mAsyncRunner.request("me/photos", param, "POST", new SampleUploadListener());

根据错误消息，它看起来像是从意图的包中获取字节时出错......
