In this blog post, we will guide you through the steps to build your own video chat app on Android using .
Before you start application development, it is important to have a basic understanding of the following technologies:
If you’re new to these technologies, don’t worry! There are plenty of resources to help you stay informed. Once you’ve mastered the basics, do the following:
To use the video chat API, you must create a developer account. To do this, simply go to the website and register for a free account. After you sign up and verify your email address, you can log in to the developer portal and view the API key for your organization.

Copy API keys. These API keys are unique to your organization and are required to use the REST API, for example when creating a meeting.
Create presets using the developer portal. A preset is a set of user interface configurations and permissions that are applied to participants.
If you don’t want to use an Android emulator, you can use two Android devices instead. The device can be a smartphone or tablet running Android Lollipop or higher.
Now that we’ve met all the requirements, let’s delve into the steps required to create an Android video chat app using . You just need to do the following:

In this comprehensive guide, we’ll walk you through the process of building a real-time chat app using the powerful MERN stack and integration for seamless notifications. By combining the powerful features of MongoDB as a database, Express.js for server-side development, React.js for building dynamic user interfaces, and Node.js as a runtime environment, we will create a highly scalable and efficient chat application.
In addition, we will leverage the capabilities of our versatile notification platform to improve user engagement and provide real-time updates. Some business use cases for real-time chat applications are as follows:
Install Nodemon. Nodemon is a Node.js tool that automatically restarts the server after detecting file changes, and Socket.io allows us to configure real-time connectivity on the server.

Configure Nodemon by adding the start command to the list of scripts in the package.json file. The code below starts the server with Nodemon.
If you are not using nodemon, start the server with the command “node index.js” or modify the script by adding the start command to the list of scripts in the package.json file, as shown below
Install the Socket.io API client and React Router. React Router is a popular routing library for React applications. This allows us to handle navigation and routing declaratively in React components.
We will also use React Toastify and Emoji-mart here. Emoji Mart is an npm package used to bring emojis into chats.

Remove unnecessary files such as logo and test files from the React app and update the App.js file to display Hello World as below. Run npm start to ensure that the application works correctly.
Also create a folder called pages in src and create chatpage.js in it. This page, as the name suggests, is responsible for handling the appearance and functionality of the chat in the application.
We will use the Context API to track authentication and user information. Create a folder called context in src and create context.js in it.
Now App.js will change to redirect to the chat page when the user logs in. If an unauthorized user tries to access the chat page route, he or she will be redirected to the login page.

Now let’s complete the login and list components. Let’s customize the login and registration components to configure UseNvigate hoo and handle the login and registration functionality:
Also create an .env file in the root folder (the parent folder contains public, src, etc.) and add the following content
Now let’s make models. Create directory model. In models, create user.js, chat.js, and message.js to create schemas for user, chat, and message details and their respective models.
Install the verification package first. The Validator package offers a variety of features to validate different types of data such as URLs, emails, dates, and mobile numbers, among others. You can also use it for data cleaning.

Add details such as JWT_SECRET and JWT_LIFETIME to the env file. JWT_SECRET is a secret message that can be a string used for encryption, and JWT_LIFETIME specifies how long the jwt is valid. It can take values such as 30m, 10d, etc. in 30 minutes, 10 days.
Now create routes in the backend for registration, login, messaging and chatting. We use an express router for this. Create a folder called routes in the root folder and create 3 files auth.js, chat.js and message.js inside routes.
Since we are using jwt, we also need to verify the jwt of any user trying to access the routes. Let’s create a folder called middleware in the parent folder of the project. Create a file in it called auth.js. Enter the code below into it.
The MyChats.js file contains a list of all user chats. Enter the following code there.

Write the code below in components/singlechat.js to handle the chat window functionality and add styling for different components like messages, input bars, etc. Note that here we will use socket.io and cover different aspects to enable real-time communication to guarantee. I also used 2 SVG icons here. You can use your favorite symbols and adjust the code accordingly.
Insert the following code into sidebar.js. This component allows the user to search for any other user and add them to the post.
The scrollable chat element is the part of the chat window where messages are stored. Place the code below in components/scrollablechat.js
Now let’s create the components for the group chat. The Groupchatmodal component is used to create a group. In components/groupchatmodel.js, enter the following code:

Mazel Tov. We have completed the user interface of the chat application. Let’s also complete the backend code. First we import the server from socket.io, then add it to cors and finally we connect to the frontend. We then handle all aspects of the chat via socket.io. Open index.js and add code for socket.io and various related events.
Using powerful push notification capabilities, your chat app can send instant notifications and updates to users’ devices, even when they’re not actively using the app. This keeps your users connected and informed, while promoting better communication and user engagement.
The benefits of using push notifications in chat apps are numerous. Here are some key benefits:
We can implement web push notifications for this chat application. We can use the customer’s JavaScript SDK for this.

Add the Service Worker file to your client application. Create a file called serviceworker.js in the public folder (this file must be publicly accessible) and insert the following content into it:
Initialize the SDK. Make sure you initialize it before calling any of the other methods. Since we are using create-react-app, we will initialize it at the top of the application layer in App.js. To initialize the SDK, you will need the WORKSPACE KEY and WORKSPACE SECRET and VAPID KEY. Generate a Vapid key when your account is created. You can find this key on the provider page in the control panel. Go to the Provider > Web Push > VAPID Key page, copy the VAPID public key and paste it here into the vulgar key object entry
Replace WORKSPACE_KEY and WORKSPACE_SECRET with your workspace values. You get both tokens from the dashboard (Settings page -> “API keys” section).
Sign up for web notifications. The SDK provides a service agent registration method that allows your site to request permission to notify users if it is not already enabled.

After configuring the workflow, you can pass the event name (NEW_MSG in our case) defined in the workflow configuration of the SDK and the corresponding workflow will be activated. Variables added to the template must be passed as event properties
Here property_obj is an object (optional). Additional data related to the event (event attributes) can be tracked using
