现在我的问题是，当我使用Facebook android应用程序点击通知时，我的应用程序启动了，但我无法获取该通知的请求id

应用程序仪表板配置

我想您没有忘记

requestId

属性：

private String requestId;

您还可以检查

onActivityCreated

方法中的

intentUri

、

requestIdParam

和

array[0]

的值吗

@Override
public void onActivityCreated(Bundle savedInstanceState) { // <--- in THIS method
    super.onActivityCreated(savedInstanceState);
    Log.d(TAG, "MainFragment.onActivityCreated()");

    // Check for an incoming notification. Save the info
    Uri intentUri = getActivity().getIntent().getData();
    Log.d(TAG, "intentUri: " + intentUri.toString()); // <--- HERE
    if (intentUri != null) {
        String requestIdParam = intentUri.getQueryParameter("request_ids");
        Log.d(TAG, "requestIdParam: " + requestIdParam); // <--- HERE
        if (requestIdParam != null) {
            String array[] = requestIdParam.split(",");
            Log.d(TAG, "requestId: " + array[0]); // <--- HERE
            requestId = array[0];
        }
    }
}

但是，您无法获得

请求\u id

参数。在我看来，以下配置有问题：

你在这些字段中输入了什么？它与你的实际应用程序相符吗

编辑2:

类名：这是您想要的主要活动的类名 Facebook即将发布

您的

Login.java中有什么内容
它应该是com.pricus.expensemanagement.MainActivity

确保您正确地遵循了以下步骤，尤其是：
首先，使活动子类FragmentActivity代替
活动：
这是一个我花了一整天时间解决的问题。多亏了波班
这是Facebook的bug。只需在应用程序仪表板中添加移动Web，您将获得请求ID
否，我要求您打印上述变量的值。在此处使用语句进行后期编辑。这样做，然后用三个log.d
的结果进行回答。在logcat中，我将再次读取我的最后一条评论并回答请求。真不敢相信你的帖子增加了+50，你甚至都懒得认真回答。我想要3（三）个值。对不起。我已经添加了logcat输出了。真的吗？这仍然不是我想要的。我从一开始就知道，requestId在onSessionStateChange
中为空。您的logcat输出说明了我们已经知道的内容。但是告诉我，你读过我写的东西吗？我要求您在onActivityCreated
方法中添加3个logs.d
。在三次评论之后，你仍然不理解，我们根本没有进步。（好的，我会给你一个提示，因为我很好：你只需要将我的onActivityCreated方法复制/粘贴到你的代码中）。然后再次更新logcat输出。你好，Nick，我有同样的问题，你也可以检查我的问题。如果可能的话，请帮我解决这个问题。
