It is possible to do it via the API interface, but for this tutorial, we’ll be creating our users manually in the console.Also go to the Credentials tab of the console and make a note of the Instance Locator, and the Token Endpoint. In this class, create a few MutableLiveDatas, then get an instance of ChatManager.The class has two constructors. You need to subscribe any of the channel and all the subscribers will get the messages . We can’t join a room that doesn’t exist, nor can we create a room that’s already been created.The workaround is we can get a list of the rooms a user can join and use simple logic to see if our constructor’s roomId belongs to that list.Finally, we have our 3 functions for Creating, Joining, and Leaving rooms. You should see an interface like this: Testing with the debug console. First, ensure you have updated your the PUSHER_API_KEY in the MainActivity class with your Pusher Key. operators here. The LobbyActivity simply has a text field where we enter a room number to join. As with most things, a production app in this case would be better made with dependency injection (Dagger), but for the sake of simplicity of simplicity, I’m not using it for this tutorial.Chatkit’s developer area provides us with some very useful information including an Analytics dashboard, and a console where we can view our users, rooms, and messages which will help us as we go along.It’s also worth noting that for security purposes, there isn’t a straightforward way the Android SDK allows us to create or delete users. * you may not use this file except in compliance with the License. Run the Android application either using a real device or a virtual one. These operations are normally done on the backend and therefore, are available on the backend SDKs of Chatkit. Oracle JDK; OpenJDK; Android, via this wrapper SDK Again, I would have ideally included more logic here by letting the ViewModel handle the results of a The two components you need to know about here are the RecyclerView of messages in the chat, and a layout of an EditText and Button for sending messages.Speaking of the RecyclerView, here’s the adapter I’m using.This is a bit more involved so I’ll explain what’s going on here.An Android Developer who loves exploring the realm of Android Architecture Components as much as the secrets of cocktail mixology.By buying me a coffee, you show your love for the blog and enable me to bring you better contentKeep me fueled up so I can provide you with the best content! Creating the Repository. I’m working on it).When the ChatRepository is no longer used, we have to close As mentioned above, we’ll have 2 activities so that means 2 ViewModels as well. Pusher Channels client library for Java targeting Android and general Java.. Instant messaging is undoubtedly one of the most widely used features of any app that users all across the world make use of. Pusher is their API for realtime in-app chat and includes SDKs for Android, iOS, JavaScript, and even React, and that’s just their front-end SDKs. *  Licensed under the Apache License, Version 2.0 (the "License");  *  you may not use this file except in compliance with the License. I’m going to show you how to do exactly that with Pusher Chatkit.There are quite a few instant messaging tools out there that can be easily deployed in Android. The LobbyActivity is only concerned with joining rooms, so we have our I decided to pass Context into the single method of Other than the ViewModel binding here, all you have to know about this layout is the edit text field for the RoomId, and the Button to kick things off, verify the roomId, and start an intent to the MainActivity.As for the Kotlin code, here are the important functions.When the Send Button is clicked, the task is delegated to the ViewModel to verify the room and either join or create it. I would have preferred the synchronous approach as that would have allowed me to delegate the logic to the ViewModel, rather than handling it in the Repository.We have 3 pieces of LiveData we need to populate: ChatkitUser, Room, and Messages. They also have SDKs for the back-end, as well as an API interface.Chatkit works through users joining a room with a given ID, and being able to subscribe to those rooms where they can receive existing messages in that room, as well as any new ones almost immediately after they are sent.It has a strong reputation and is used by many big apps and companies such as Monzo, Duolingo, and even Github, just to name a few.Other Chatkit features include Push Notifications, Webhooks, and Indicators for read, typing, and online presence.This is a simple app that contains 2 activities.

Once either operation completes, I only included the key functions here related to our Chatkit data flow, but if you want the full code, I linked the Github repository for this project below.The ViewModel here simply establishes the connection between the View and the Repository.
