我在FirebaseMessagingServices上遇到了一些问题。
我有一个包含两个应用程序的项目，我们可以在其中将数据消息（带有有效负载的通知）从一个应用程序发送到另一个应用程序。当它们在前台时，它们在后台运行时工作正常，但是它们之间的间隔只有30分钟。
我的意思是说，如果该应用被杀死，则大约30分钟或一个小时后，它不会收到消息。我认为30分钟后他们将与Firebase断开连接，我不希望这种情况发生。如果要断开连接，则它应重新连接到Firebase本身，直到移动设备中可以连接互联网。
我做了很多研究，最终找到了BROADCAST个接收器。即使该应用程序被杀死，它们也可以工作。因此，一旦断开连接，我如何使用Broadcast接收器与Firebase重新连接？
这是我的课程：

我需要在服务和活动（BroadcastReciever服务-> FirebaseMesssaging-> Broadcastreceiver）之间实现Activity的帮助。
我想要的是，应用程序应该与FirebaseMessagingServices或Whatsapp或{{1 }}应用中，即使我几个小时前将其杀死，它们也会发送通知。
不是我只需要Uber的帮助；如果还有其他方法，请与我分享。
