Firebase Firestore Chat App: Sign-In & Setup (Ep 1) – Kotlin Android Tutorial

Firebase provides a bunch of awesome services such as Firestore, Auth, Cloud Storage, Cloud Functions and Cloud Messaging. Learn how to use them in this tutorial course in which we’re making a fully fledged real-time chat app with everything you’d expect like sending images and getting notifications when we receive a new message.

In this part you will learn how to set everything up in the Firebase Console and we will also sign our users in with Firebase UI Auth. We will also create a splash screen and we will do it the right way – without inflating any layout!

This post contains all the code that’s been written in this YouTube video.
