Android Facebook Open Graph 帖子不起作用

Question

我正在尝试通过我的应用发布一个开放的图表故事，这是我正在使用的代码：

OpenGraphObject trip = OpenGraphObject.Factory.createForPost("project_name:city");
                    trip.setProperty("url", "http://samples.ogp.me/670838023004167");
                    trip.setProperty("title", "Sample City");
                    trip.setProperty("description", "");
                    trip.setType("project_name:city");
                    OpenGraphAction action = GraphObject.Factory.create(OpenGraphAction.class);
                    action.setProperty("trip", trip);
                    action.setProperty("previewPropertyName", trip);
                    //action.setType("project_name:city");
                    FacebookDialog shareDialog = new FacebookDialog.OpenGraphActionDialogBuilder(ShareTripActivity.this, action, "me/project_name:travel", "trip")
                            .build();
                    shareDialog.present();
                    uiHelper.trackPendingDialogCall(shareDialog.present());

我得到的对话框生成了几秒钟，但在用户可以做任何事情之前它关闭并返回到上一个屏幕。它给出了一条错误消息“无法为用户生成预览”，但应用程序不会崩溃。可能是什么问题？ 谢谢

我在另一个帖子中看到了解决方案：

解决方案是动作词必须与 facebook 设置的完美匹配。 看到这一点的唯一方法是打开类型的图形代码生成器。

https://developers.facebook.com/apps/{app-id}/opengraph/types

您可以在上面的操作类型部分的链接中找到它。

现在，将 facebook 提供的命名空间和操作类型替换为下面的“appnamespace:action”。

OpenGraphAction action = GraphObject.Factory.create(OpenGraphAction.class);
        action.setProperty("object", "http://object.url");

FacebookDialog shareDialog = new FacebookDialog.OpenGraphActionDialogBuilder(this, action, "appnamespace.action", "object")
                .build();
uiHelper.trackPendingDialogCall(shareDialog.present());

它已弃用工作..

private Facebook facebook = new Facebook(APP_ID);

public void postToWall() {
    // post on user's wall.
    facebook.dialog(this, "feed", new DialogListener() {

        @Override
        public void onFacebookError(FacebookError e) {
        }

        @Override
        public void onError(DialogError e) {
        }

        @Override
        public void onComplete(Bundle values) {
        }

        @Override
        public void onCancel() {
        }
    });

}

private void publishFeedDialog() {
Bundle params = new Bundle();
params.putString("name", "Facebook SDK for Android");
params.putString("caption", "Build great social apps and get more installs.");
params.putString("description", "The Facebook SDK for Android makes it easier and faster to develop Facebook integrated Android apps.");
params.putString("link", "https://developers.facebook.com/android");
params.putString("picture", "https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png");

WebDialog feedDialog = (
    new WebDialog.FeedDialogBuilder(getActivity(),
        Session.getActiveSession(),
        params))
    .setOnCompleteListener(new OnCompleteListener() {

        @Override
        public void onComplete(Bundle values,
            FacebookException error) {
            if (error == null) {
                // When the story is posted, echo the success
                // and the post Id.
                final String postId = values.getString("post_id");
                if (postId != null) {
                    Toast.makeText(getActivity(),
                        "Posted story, id: "+postId,
                        Toast.LENGTH_SHORT).show();
                } else {
                    // User clicked the Cancel button
                    Toast.makeText(getActivity().getApplicationContext(), 
                        "Publish cancelled", 
                        Toast.LENGTH_SHORT).show();
                }
            } else if (error instanceof FacebookOperationCanceledException) {
                // User clicked the "x" button
                Toast.makeText(getActivity().getApplicationContext(), 
                    "Publish cancelled", 
                    Toast.LENGTH_SHORT).show();
            } else {
                // Generic, ex: network error
                Toast.makeText(getActivity().getApplicationContext(), 
                    "Error posting story", 
                    Toast.LENGTH_SHORT).show();
            }
        }

    })
    .build();
feedDialog.show();

}

使用此代码.. 它以图表故事的形式将数据分享给 facebook！
