How to get a push notification about a user's tweet?

Question

Android

You need to track the twitter feed of a specific account. When you receive a new tweet, push in the app. How to implement such functionality? Tried a bunch of OneSignal+Zappier+FCM. But unfortunately it is paid.

Answer 1

1) Write a twitter feed parser
2) Understand how push notifications work ( a book from the creator ), there is a demo for the desktop, you can still click
3) Understand FCM, read articles on how to create an fcm project in a google account and implement it in your own project ( example article )
4) Refine clauses 1,2,3 in conjunction
with OneSignal and similar services can simplify clauses 2,3,4, but they are paid, as you yourself indicated :)
