Building a Messenger Using Firebase - Android

This lecture shares how to create a messenger similar to KakaoTalk without implementing a backend server. Since this lecture uses Firebase, you must have prior knowledge of Android to take the course. Most of the lecture content is structured around logic, and this lecture is implemented using Firebase. If you understand this lecture well, you can implement a messenger using other message protocols.

What you will learn!

  • Understanding the database structure and architecture of a Firebase-based messenger application

  • Setting up a development environment using Android Studio

  • Implement user authentication, friend registration, and chat functions

  • Real-time message updates and notifications

  • Firebase Analytics Integration

1. Course Introduction

This lecture will combine the features of Firebase to implement a messaging service (messenger). The Android application being implemented will primarily support one-on-one and one-on-many chat with friends. We'll use Firebase features as a replacement for the messaging protocol to implement the messaging service.

The main content consists of how to implement a commercial service using the real-time synchronization feature, a key feature of real-time databases. As you listen to the lecture, you'll likely come across many features you'd like to implement.

2. People who can help

  • For those who want to know the principles of messaging services
  • If you need to implement a messenger using Android, but need a message server
  • Those who need to develop efficiently and quickly using Firebase's real-time synchronization function

3. Application Configuration

Login screen

  • Google login

Chat lobby screen

  • Chat screen
  • Create a new chat room
  • Send/receive messages (text, images)
  • Message read processing
  • Leave chat room

Friends list

5. Instructor Introduction

Hello. I'm Shin Huttchang, a Java Backend developer . I started developing in 2012, and I've been enjoying it ever since. I learned about Firebase through Google I/O in 2016, and as a backend developer, I thought it could have a significant impact on my work, so I started researching it extensively. The more I learned about Firebase, the more I realized its fascinating features. Among the many applications, I've been curious about chat, so I wanted to share it with you. I hope you enjoyed it, and if you have any questions, please leave a comment or email me. I'll be happy to answer. Thank you. Email: huttchang@gmail.com

      The code is from a lecture from a few years ago, so there are some parts that need to be fixed, but if you have a little knowledge, it is an error that can be easily found. The lecture itself seems very good. It explains everything in detail, from comments to explanations. It seems good because you can learn how to use it overall.
