Question

在我的Android应用程序中，我正在尝试共享包含对象和动作的开放图表在我的Facebook应用程序中，我添加了一个故事：action="take"和object="photo"（这可以吗？）。

当我尝试将图像添加到OG中的对象时，我得到了上述错误。

这是我的代码：

private void shareWithFacebookOpenGraph(String pathToImage) {
    Log.i("SHARE", "1. share with OpenGraph");  
    OpenGraphObject photo = OpenGraphObject.Factory.createForPost("myapp:photo");
    photo.setProperty("title", "MyApp Photo");
    photo.setProperty("image", "http://play.google.com/to_my_app_launcher_icon");
    photo.setProperty("url", "http://play.google.com/to_my_app");
    photo.setProperty("description", "Image taken with myApp for Android");

    List<File> files = new ArrayList<File>();
    files.add(new File(pathToImage));

    OpenGraphAction action = GraphObject.Factory.create(OpenGraphAction.class);
    action.setProperty("photo", photo);

    FacebookDialog shareDialog = new FacebookDialog.OpenGraphActionDialogBuilder(this, action, "myapp:take", "photo")
        .setImageAttachmentFilesForObject("photo", files, true) // **Error**
        .build();
    uiHelper.trackPendingDialogCall(shareDialog.present());
}

这是logcat：

我做错了什么？也许我在故事中弄乱了一些字符串，facebook教程很糟糕！

Answer 1

您已经在照片对象中设置了图片。如果您以后要将图像添加为附件，请删除该行。
