无法为用户生成预览--Facebook android SDK 4.2

Question

我目前正在facebook上共享一个位置。

这是我的代码

// Create an object
            ShareOpenGraphObject object = new ShareOpenGraphObject.Builder()
                    .putString("og:type", "anewplace")
                    .putString("og:title", "Paris")
                    .putDouble("place:location:latitude", 10.7672788)
                    .putDouble("place:location:longitude", 106.6877127)
                    .build();
            // Create an action
            ShareOpenGraphAction action = new ShareOpenGraphAction.Builder()
                    .setActionType("come")
                    .putObject("anewplace", object)
                    .build();
            // Create the content
            ShareOpenGraphContent content = new ShareOpenGraphContent.Builder()
                    .setPreviewPropertyName("anewplace")
                    .setAction(action)
                    .build();

            ShareButton shareButton = new ShareButton(this);
            shareButton.setShareContent(content);
            shareButton.registerCallback(callbackManager, new FacebookCallback<Sharer.Result>() {
                @Override
                public void onSuccess(Sharer.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!");
                }
            });
            shareButton.performClick();

我收到一个错误：无法为用户生成预览

我按照文档创建了一个自定义故事

请帮忙：(谢谢

我找到了方法：(

对于操作，其格式应为"app_name:action_name"对于对象，它应该是"app_name:object_name">
