收到 firebase 通知时打开活动，而无需单击通知

Question

我正在构建一个具有呼叫功能的应用程序。因此，我收到了来自服务器的通知，并构建了一个活动来显示呼叫屏幕，其中我有接听和挂断按钮。

现在我有一个问题，当应用处于后台/被杀死或手机被锁定时，我应该使用什么来启动 Activity？

我尝试在 FirebaseMessagingService 的 onMessageRecieved 函数中启动活动，但我认为当应用程序处于后台时不会调用该函数。因为当我尝试在应用程序处于后台时进行调试时，调试指针不会被触发并且活动不会打开。

Activity 在收到通知时在前台打开，但在应用处于后台时不会。

这是我的服务

    private var pendingIntent: PendingIntent? = null

    override fun onMessageReceived(remoteMessage: RemoteMessage) {
        Log.e("get_type_data", remoteMessage!!.data.toString())
        val data = remoteMessage.data
        val myCustomKey = data["notification_data"]

        if(!myCustomKey?.length?.equals(0)!!)
        {
            createNotification(remoteMessage.data)
        }

    }

在显示通知之前添加此行

notificationBuilder.setFullScreenIntent(pendingIntent, true);
