Question

在tutorial之后，我尝试使用Facebook SDK 4.0在Android应用程序中实现OpenGraph故事。
我已经阅读了很多Facebook文档，并且（理论上）理解OpenGraph故事应该如何工作。但主要的问题是，我无法在SDK 4.0中实现它，因为教程和文档中的所有代码示例都引用了旧的SDK方法。而我所有使它成功的尝试（改变动作，对象）都失败了。

这是我的代码（根据documentation ）：

// Create an object
ShareOpenGraphObject object = new ShareOpenGraphObject.Builder()
        .putString("og:type", "books.book")
        .putString("og:title", "A Game of Thrones")
        .putString("og:description", "In the frozen wastes to the north of Winterfell, sinister and supernatural forces are mustering.")
        .putString("books:isbn", "0-553-57340-3")
        .build();

// Create an action
ShareOpenGraphAction action = new ShareOpenGraphAction.Builder()
        .setActionType("books.reads")
        .putObject("books:book", object)
        .build();

// Create the content
ShareOpenGraphContent content = new ShareOpenGraphContent.Builder()
        .setPreviewPropertyName("books:book")
        .setAction(action)
        .build();

ShareButton shareButton = (ShareButton)findViewById(R.id.shareButton);
shareButton.setShareContent(content);
shareButton.registerCallback(callbackManager, new FacebookCallback<Sharer.Result>() {

    @Override
    public void onSuccess(Result result) {
        Log.i(TAG, "SHARING SUCCESS!");
    }

    @Override
    public void onError(FacebookException error) {
        Log.e(TAG, "SHARING ERROR! - " + error.getMessage());
    }

    @Override
    public void onCancel() {
        Log.w(TAG, "SHARING CANCEL!");
    }
});

我得到了什么（我所有的尝试）： enter image description here

动作需要至少一个参考：你正在尝试的动作发布无效，因为它未指定任何引用对象。必须至少指定以下属性之一：book。

请解释一下，如何在FB SDK 4.0中正确使用OpenGraph，并使用SDK 4.0方法正确使用Objects和Actions。

对话框的webview版本有一个错误已得到修复。您需要对代码进行一处小改动，我也会更新我们的文档：

// Create an action
ShareOpenGraphAction action = new ShareOpenGraphAction.Builder()
    .setActionType("books.reads")
    .putObject("book", object)  // <--- don't namespace the object on the action
    .build();

// Create the content
ShareOpenGraphContent content = new ShareOpenGraphContent.Builder()
    .setPreviewPropertyName("book")  // <--- don't namespace the preview property
    .setAction(action)
    .build();

万一有人在寻找它，这就是我解决问题的方式。

还有一个问题，当我尝试使用另一个CallbackManager.Factory.create();时，我的FacebookCallback<Sharer.Result>未被通知，我对所有Facebook动作只使用了一个实例。

public static void faceBookShareDialog(KoboActivity activity, Content content, Bitmap imageToShare,
            String textToShare) {
        ShareHashtag shareHashtag = new ShareHashtag.Builder().setHashtag(HASH_TAG_KOBO).build();

        SharePhoto photo;
        if (!isFacebookInstalled(activity)) {
            ImageConfig imageConfig = Application.getAppComponent().imageConfigFactory().create(content.getImageId(), ImageType.Cover);
            String imageUrl = imageConfig.getImageRequestURL();

            photo = new SharePhoto.Builder()
                    .setImageUrl(Uri.parse(imageUrl))
                    .build();
        } else {
            photo = new SharePhoto.Builder()
                    .setBitmap(imageToShare)
                    .build();
        }

        // Create an object
        ShareOpenGraphObject object = new ShareOpenGraphObject.Builder()
                .putString("og:type", "books.book")
                .putString("og:title", content.getTitle())
                .putString("og:description", content.getDescription())
                .putString("books:isbn", "0-553-57340-3")
                .putPhoto("og:image", photo)
                .build();

        // Create an action
        ShareOpenGraphAction.Builder actionBuilder = new ShareOpenGraphAction.Builder()
                .setActionType("books.quotes")
                .putString("body", textToShare)
                .putObject("book", object);

        // Create the content
        String contentURL = generateFacebookShareUrl(content.getId(), content.getType(), CreatePhotoQuoteActivity.CAMPAIGN);
        ShareOpenGraphContent contentGraph = new ShareOpenGraphContent.Builder()
                .setPreviewPropertyName("body")
                .setShareHashtag(shareHashtag)
                .setAction(actionBuilder.build())
                .setContentUrl(Uri.parse(contentURL))
                .build();

        FacebookCallback<Sharer.Result> shareCallback = new FacebookCallback<Sharer.Result>() {
            @Override
            public void onCancel() {
                Log.i("FBShare", "fb SHARE canceled");
            }

            @Override
            public void onError(FacebookException error) {
                Log.e("FBShare", "fb SHARE error");
                error.printStackTrace();
            }

            @Override
            public void onSuccess(Sharer.Result result) {
                String postId = result.getPostId();
                Log.i("FBShare", "fb SHARE success ");
                if (postId != null) {
                    // record successful FB share
                    Log.i(TAG, "post id: " + postId);
                }
            }
        };

        SharePhotoContent photoContent = new SharePhotoContent.Builder()
                .addPhoto(photo)
                .setShareHashtag(shareHashtag)
                .build();

        ShareDialog shareDialog = new ShareDialog(activity);
        shareDialog.registerCallback(activity.getCallbackManager(), shareCallback);

        shareDialog.show(photoContent);

    }
