从 Web 服务器推送通知到 android 应用程序

Question

Hello to everyone who is viewing this question. I think this question might be quite abstract, but I couldn't find the correct answer by googling.

I am trying to make an application like Starbucks Siren-Order.

Our android applications are made in Android-Java , and we are also developing a web-server which is also written in Java , using Spring-MVC .

Once a customer makes an order using this application(which is for customers), I want to make push notifications appear in Store-Owner-Application . I was thinking about using WebSocket, but is Firebase a great alternative for websocket in this case? I never used neither WebSocket or Firebase before. Just asking for some tips and advice. Thank you:)

Answer 1

in simple cases, Firebase is a much better alternative to implementing it yourself using WebSocket.

That's because Firebase already has a battery draining constantly open socket to handle its notifications, and since most apps use it rather than creating a new socket, it helps conserve battery and other resources.

There are a few exceptions though.. Firebase isn't perfect, it allows sending messages to the client most of the time , and in some cases, your notification will be delayed, or won't get delivered at all. For example:

1. If the battery is low
2. if the device received many push notifications recently

If you need a simple 99% solution to sending push notifications that is easy to implement and won't waste battery - Go with Firebase.

If you have to have full control over your notifications and need them delivered all the time, as soon as possible, consider implementing it yourself.
