无法生成preVIEW用户 [英] failed to generate preview for user

问题描述

我想从一个Android模拟器Facebook的文档实现这一点。

I'm trying to implement this from the facebook docs on an Android Emulator.

https://developers.facebook.com/docs/android/share-dialog /

OpenGraphAction action = GraphObject.Factory.create(OpenGraphAction.class);
action.setProperty("book", "https://example.com/book/Snow-Crash.html");

FacebookDialog shareDialog = new FacebookDialog.OpenGraphActionDialogBuilder(this, action, "books.reads", "book")
        .build();
uiHelper.trackPendingDialogCall(shareDialog.present());

这一直给错误消息

It keeps giving the error message

错误：com.facebook.FacebookException：无法生成preVIEW用户

Error: com.facebook.FacebookException: Failed to generate preview for user.

我使用的是FbAndroid-3.9.apk

I'm using the FbAndroid-3.9.apk

我有一个命名空间，但没有appened书。

I've appened the book with a namespace but nothing.

推荐答案

这是如何使用Facebook的对话框中设置了一个开放的图形操作。

This is how you can set up an open graph action using facebook dialog.

OpenGraphObject setObj = OpenGraphObject.Factory.createForPost("your app namespace:object type");

setObj.setProperty("title", "Title required");

/ *对于歌曲的内容类型music.song。您可以在此链接搜索找到你的对象的内容类型 https://developers.facebook.com/docs/opengraph/music * /

/* For songs content type is music.song. You can search in this link to find content type of your object https://developers.facebook.com/docs/opengraph/music */

                    setObj.getData().setProperty("type", "content type of your object");
                    setObj.setProperty("url", "your url");

                    setObj.setProperty("description", "your description");
                    OpenGraphAction action = GraphObject.Factory.create(OpenGraphAction.class);

/ *你的行动是行动，你设置为开放式图形为您的应用程序* /

/* Your action is the action you setup as open graph for your app */

                    action.setType("your app name space:your action");

/ *你的对象名称可以是一首歌或类似的东西* /

/* Your object name can be a song or something like that */

                    action.setProperty("your object name", setObj);

/ *最后* /

/* And finally */

                    FacebookDialog shareDialog = new FacebookDialog.OpenGraphActionDialogBuilder(context, action, "your object name").build();
                    uiHelper.trackPendingDialogCall(shareDialog.present());
