我也遇到过类似的问题。我已经尝试了一切——在我看来，主要原因是所有的服务迟早都会被系统扼杀。唯一的方法是确保将通知发送到系统托盘，而不是应用程序。为此，您需要使用数据消息通知

FCM通知有两种类型：通知消息和数据消息

数据消息被传送到系统托盘并始终显示-即使服务未运行

通知消息如下所示：

{
  "message":{
    "token":"bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
    "notification":{
      "title":"Portugal vs. Denmark",
      "body":"great match!"
    }
  }
}

并触发FirebaseMessagingService的MessageCeaved（）方法。许多设备（尤其是华为和小米）都试图尽一切努力终止后台服务，以防止电池耗尽。因此FirebaseMessagingService不是处理通知的最佳方式

第二种类型是数据消息：

{
  "message":{
    "token":"bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
    "data":{
      "Nick" : "Mario",
      "body" : "great match!",
      "Room" : "PortugalVSDenmark"
    }
  }
}

此类型由系统托盘处理，因此您不需要运行任何服务来获取通知。这是一种更方便的方法，但据我所知，它无法通过控制台实现

您可能需要服务器API来发送数据消息。
