Remote communication became even more important after the pandemic, and mobile applications now often include voice or video chat functionality. However, building this complexity from scratch can be challenging. This is where Video SDK comes into play, providing developers with simple-to-use APIs to embed real-time video, voice, and interaction functionalities into their applications without requiring them to develop the underlying technology themselves. The Video SDK allows developers to create 1-to-1 video chat apps with ease, using a pre-built SDK that can be integrated in just 10 minutes. The app uses Android Studio, Java Development Kit, and Android SDK API Level 21 or higher, and it requires runtime permissions for audio and camera access. The app has two screens: joining screen and meeting screen, which display participants as mini or large views depending on whether they are the local participant or another participant. The app handles meeting events such as join/leave and participant join/leave, and resources are released when the app is closed to avoid memory leaks.

The React Native Video Call App uses Call Keep for push notifications on iOS devices, allowing users to initiate video calls and receive notifications in the background. The app is built using React Native and Firebase, with a focus on server-side setup using Node.js and the `node-apn` library. The client-side code sets up the necessary libraries and handles push notification registration, while the server-side API sends APN notifications for iOS devices and FCM notifications for Android devices. With this implementation, users can now make video calls on both Android and iOS devices, with features like screen sharing and chat messaging planned for future development.

Video conferencing is increasingly essential yet complex for developers to implement, often requiring frameworks like React Native and WebRTC to create applications for real-time communication. React Native facilitates the development of native mobile applications for both iOS and Android using JavaScript, allowing code sharing across platforms. WebRTC, an open-source protocol, enables peer-to-peer communication through voice, text, and video, utilizing technologies like SDP, ICE, and RTP, along with a signaling server for connection establishment. A step-by-step guide is provided for building a video call application using Node.js with SocketIO as the signaling channel and React Native for the client-side app, including setting up permissions and configurations for Android and iOS. The guide also covers creating the user interface, establishing WebRTC calls, managing local and remote media streams, and handling audio routing using third-party libraries. For simpler integration, Video SDK is recommended as it offers a more developer-friendly approach to incorporating live video and audio into React Native projects with enhanced customization and data access capabilities.

In a world where we are all connected through phones over audio and video calls, if you are planning to make one such app, you have landed at the right place. We will be building a complete video calling app in React Native, which will allow you to make and receive video calls seamlessly. We'll use VideoSDK for video conferencing and React Native CallKeep to manage the call UI. This is a two-part series in which we will first implement CallKeep in Android and then configure and tweak it for iOS.

The e-commerce industry continues to grow and become increasingly popular, driven by its ability to provide an engaging and interactive shopping experience. Live commerce, also known as live shopping or live streaming shopping, is a form of e-commerce where sellers promote and sell products in real-time through live video broadcasts, combining elements of traditional TV shopping channels with the interactivity and convenience of online shopping. This industry has gained significant popularity in recent years, especially in countries like China and South Korea, and has been adopted by many brands and retailers to engage with consumers and drive sales. Technology plays a crucial role in making live commerce more interesting, offering features such as improvised recommendations, high information density, increased conversion rates, and low latency live streaming. Various platforms support live commerce, including social media platforms like Facebook, Instagram, and TikTok, as well as dedicated live streaming platforms such as Amazon Live and eBay Live. With the rise of social commerce, individuals can leverage live streaming features on social media platforms to showcase and sell products to their audience. As technology continues to evolve, we can expect to see even more exciting developments in live commerce, including the integration of augmented reality, virtual reality, and artificial intelligence, creating real-time experiences that are both fascinating and accessible.
