Question

我正在创建一个Android应用程序，我想使用其ShareOpenGraph功能将帖子分享到Facebook。我一直在关注FB提供的在线教程，实际上只是将其复制并粘贴到我的应用程序中（用于测试）。我有一个应用程序ID和所有内容。我可以发布其他类型的帖子，例如图像等，但是不能发布这种ShareOpenGraph类型的帖子。

当我从应用程序中单击“发布到Facebook”时，将弹出一个FB对话框，其中包含所有正确的信息，并且看起来很完美。

问题是，当我在Facebook的弹出对话框中单击“共享”时，出现一个Android错误，提示“ Facebook已停止”，并且我的帖子未发布到FB。

任何想法都会受到赞赏。

我的代码：（直接来自FB）

        ShareOpenGraphObject object = new ShareOpenGraphObject.Builder()
            .putString("og:type", "fitness.course")
            .putString("og:title", "Sample Course")
            .putString("og:description", "This is a sample course.")
            .putInt("fitness:duration:value", 100)
            .putString("fitness:duration:units", "s")
            .putInt("fitness:distance:value", 12)
            .putString("fitness:distance:units", "km")
            .putInt("fitness:speed:value", 5)
            .putString("fitness:speed:units", "m/s")
            .build();
    ShareOpenGraphAction action = new ShareOpenGraphAction.Builder()
            .setActionType("fitness.runs")
            .putObject("fitness:course", object)
            .build();
    ShareOpenGraphContent content = new ShareOpenGraphContent.Builder()
            .setPreviewPropertyName("fitness:course")
            .setAction(action)
            .build();
    ShareDialog.show(this, content);
