没有 Google 服务的 Android 推送通知 [英] Android push notification without Google service

问题描述

我来自 Apple 世界，所以我对 Android 没有太多经验.

I am from Apple world, so I don't have much experience with Android.

但我正在寻找一种无需使用任何第三方服务器即可让 Android 设备接收推送通知的方式.通知需要是标准的 Android 通知(外观和感觉)

But what I am looking is a way that Android devices receive push notification, without using any third party servers. Notification need to be standard Android notification (look and feel)

我需要这个的原因是，因为我需要在一个无法进入外部世界的房间里.(无法连接到任何服务器)但我有自己的 WiFi，因此用户可以通过我的 wifi 从我的服务器接收推送通知.

The reason I need this is, because I would need this in a room that does not have access to outer world. (can't connect to any server) But I have my own WiFi so users can receive push notification from my server via my wifi.

我知道在 iOS 上这是不可能的，那么 Android 呢?

I know that on iOS this is not possible, what about Android?

推荐答案

可以使用 Service 在应用程序退出后在系统(后台)中运行.一些示例这里，您应该对START_STICKY感兴趣标志

it is possible using Service left running in system (background) after app exit. some samples HERE, you should be interested in START_STICKY flag

您必须在 Service 中保留一些连接(套接字?)或间隔请求(不太好，但可能).Google 服务(包括 Firebase)自行执行此操作并将收到的推送消息重新传送"到正确声明的(在清单中)应用

you have to keep some connection (socket?) or interval requesting (not so well, but possible) inside your Service. Google Services (including Firebase) does that by itself and "redeliver" received push messages to properly declared (in manifest) app
