[Beginner Edition] Learning Android Kotlin by Building 8 Apps
bokchi
We will create 8 Android apps using Kotlin syntax. Beyond 8 practical exercises, you'll learn Android with diverse theoretical explanations.
입문
Android, Kotlin, Firebase
We will implement a simple Android 1:1 chat application using Firebase.

Simple 1:1 Chat Implementation
How to use Firebase Realtime Database
📢 Please be informed
'I wrote a few Android examples and did a simple toy project... but how do I make a chat ?'
' I don't know how to program servers, how can I send and receive data ? '
' I've heard of Firebase , but how do I use it? '
' I want to add a sign-up/login function to my app. How do I do that? '
In this lecture, we will implement a 1:1 message (chat) function using Android (Kotlin) and Firebase .
It consists of a short and simple configuration that simply implements a real-time 1:1 messaging function using Kotlin and Firebase.
This course will teach you how to use and leverage Firebase on Android.


Since this is a lecture style that proceeds like live coding , you may feel that the explanation of the code is somewhat lacking.
If you are looking for a course that is slow-paced and has a lot of explanation of the code, you may find the following course from Inflearn helpful:
Q. How difficult is the lecture?
A. If you can implement RecyclerView through search, you will be able to take the course without any problems.
Q. What features are you trying to implement?
A. Sign up / Log in / 1:1 chat.
Q. What features are there that you haven't implemented?
A. We do not implement features found in general messengers, such as group chats and PUSH messages (alarms).
We focused on simply implementing 1:1 chat functionality.
Q. Are there any precautions?
A. As the Firebase version changes, there are some parts that need to be resolved through some searches. If you share this in detail through the Q&A board, we may be able to help you, but there may be inconveniences caused by version differences.
Who is this course right for?
If you have a simple question about how to create a chat

I've seen the DB input so far, and it's good to know about Firestore. In the past, I didn't know how to use DB-related Firestore, so I modified and used a sample app made by Google. Thank you. Now I know how to do it.
Hello, Junseong Kim Thank you for listening to the lecture~ Have a nice day :)

Basically, this is a lecture for beginners who can handle Android Kotlin If it is your first time using Firebase, I can recommend it, but it is not detailed. If your goal is Firebase, I recommend another lecture Since it flows according to the flow of consciousness, I recommend listening to it all once and coding while going back rather than leaving it aside and following along Please note that following this lecture does not mean that you will get a neat app Be careful, as there are old codes mixed in, as in the review below
