Introduction

WebSockets have revolutionized real-time communication on the web, enabling bidirectional data exchange between clients and servers. In Android development, integrating WebSockets provides a powerful tool for building responsive and interactive applications. This article will explore the basics of WebSockets and guide you through the implementation process in Android, along with some code examples to help you get started.

What are WebSockets?

WebSockets provide a bidirectional communication channel over a single, long-lived connection between a client and a server. Unlike traditional HTTP requests, which are stateless and require constant polling for updates, WebSockets allow for real-time, event-driven communication. This technology enables the server to push data to the client instantly, eliminating the need for frequent requests and reducing network overhead.

Understanding WebSockets

WebSockets are a protocol that enables full-duplex communication between a client (typically a web browser or a mobile app) and a server. Unlike traditional HTTP requests, where the server responds to client requests, WebSockets allow for real-time, bidirectional communication. This capability is particularly useful for applications that require instant updates or live data streaming.

Setting Up the Project

To begin, create a new Android project in your preferred Integrated Development Environment (IDE) and ensure you have the necessary dependencies configured. One commonly used library for WebSocket implementation in Android is java-websocket. Include the library in your project by adding the following line to your app-level build.gradle file:

implementation 'org.java-websocket:Java-WebSocket:1.5.1'

Establishing a WebSocket Connection: To establish a WebSocket connection in Android, create a new class that extends WebSocketClient from the java-websocket library. This class acts as the intermediary between the client and the…
