Video call apps have evolved from simple communication tools to robust platforms that support high-quality video calls, group chats, and real-time interactions. As businesses and individuals alike embrace remote work, e-learning, and telemedicine, the need for reliable video calling apps has grown substantially. According to Agora.io, over 10 billion minutes of video calls are made each month using their platform.
For developers, Video call app development can seem like a daunting task. However, with the right tools and frameworks, such as the Agora SDK, the process becomes significantly easier. The Agora SDK allows developers to implement live video, voice calling, and other communication features into their apps with just a few lines of code.
Some of the most popular video calling platforms today include Skype, Messenger, Zoom, Duo, IMO, and FaceTime. Many of these platforms offer video conferencing features, while others focus on video chatting with strangers or friends. For developers looking to create a similar application, Agora SDK offers the ideal solution to get started quickly and effectively.
Agora SDK is a real-time communication platform that offers APIs for video calling, voice calling, messaging, and live broadcasting. It provides a set of simple, customizable tools that allow developers to integrate communication features into mobile apps quickly and efficiently. Agora has been widely adopted for its high-quality audio and video transmission capabilities, making it a popular choice for on-demand video call app development. Agora SDK supports real-time video calls with up to 17 participants, according to their official site.
Agora’s SDKs support a variety of platforms, including Android, iOS, and Web. This cross-platform compatibility makes it easier for developers to create video call apps that work seamlessly across devices. Additionally, Agora’s low-latency, high-definition audio and video ensure that users experience smooth and clear communication.
To start building your video call app using Agora SDK, you will need to follow these simple steps. First, you need to sign up for an Agora account and create a project. Once your project is set up, you can integrate Agora’s SDK into your app.
Visit the Agora Developer Console and create an account. Once you’ve logged in, click on “Create New Project.” You will be prompted to give your project a name and select the type of SDK you want to use (iOS, Android, or Web).
Once your project is created, Agora will provide you with an App ID. This ID is essential as it allows your app to authenticate with Agora’s servers and enable communication features.
Agora provides SDKs for various platforms. Whether you’re building an Android app, iOS app, or a web-based app, Agora offers the necessary tools. For Android app development, you can download the Agora SDK and integrate it into your project using Android Studio. Agora.io claims that its platform ensures high-quality video calls even with low-bandwidth conditions.
Here’s a simplified process for Android:
Once the SDK is integrated into your app, you can start configuring the video call features. Agora provides APIs to customize video layouts, adjust video resolution, and manage user interactions during video calls.
Agora SDK provides several features that are vital for developing a robust and high-quality video call app. Here are some of the key features:
Agora offers high-definition video and crystal-clear audio even in low-bandwidth situations. This feature ensures that your users enjoy clear and smooth communication without interruptions, much like popular platforms like Zoom, Skype, or Tango.
One of the standout features of Agora SDK is its real-time communication capabilities. It ensures that your video call app performs flawlessly without delay or lag, making it suitable for both personal and professional use. This is especially important in platforms like Camfrog or Meetlive, where real-time chatting with strangers or friends is crucial.
As mentioned earlier, Agora SDK supports Android, iOS, and Web platforms. This means you can develop a mobile app for Android and iOS and ensure that users on different devices can connect without any issues. Whether users are on Telegram, FaceTime, or even WhatsApp, your app will support communication across multiple platforms.
Agora SDK supports group video calls with up to 17 participants in a single video call. This makes it an excellent choice for businesses, educational institutions, or anyone who requires larger video call groups. Similar to Skype or Zoom, you can create virtual meeting spaces for collaboration and team meetings.
Another important feature provided by Agora is screen sharing. Users can share their screens with others during a call, making it ideal for presentations, tutorials, or remote troubleshooting, similar to apps like Facebook Messenger or Camchat.
When it comes to mobile app development, especially for communication apps, selecting the right SDK is crucial. Agora SDK offers numerous advantages over other alternatives:
Agora’s infrastructure is designed to scale effortlessly, ensuring that as your app grows, it can handle an increasing number of users and video call sessions without compromising on performance. Whether you are building a platform like Mico, Ace, or a niche service like Boloji, Agora can support your growth.
One of the key challenges with video calling apps is maintaining low latency. Agora’s network optimizes communication across different regions to ensure minimal lag, ensuring that users enjoy smooth and natural conversations.
Agora SDK simplifies the process of integrating video calling and real-time communication features into your app. You do not need to have advanced knowledge of video codecs or server configurations to get started. The SDK abstracts much of the complexity, allowing you to focus on the app’s user experience.
Agora ensures that all communications through its platform are encrypted using AES-256 encryption. This guarantees that your users’ data and video calls remain secure and private, similar to secure platforms like Oovoo or WhatsApp.
For businesses and startups looking for an on-demand app development solution, Agora SDK provides a cost-effective way to implement video calling without the need for complex backend infrastructure or server management.

Building a video call app with Agora SDK requires careful consideration of several factors. Here are some best practices to keep in mind while developing your app:
Ensure that your app performs well even under low-bandwidth conditions. Use Agora’s bandwidth optimization features to ensure smooth video calls, even in poor network conditions. Similar to platforms like Lucky or Omegle, the user experience should never be compromised.
The design of your app plays a crucial role in user experience. Make sure your app is intuitive, easy to navigate, and visually appealing. Agora’s customizable UI tools allow you to make your app look professional and user-friendly.
Since Agora SDK supports multiple platforms, make sure to test your video call app across different devices to ensure compatibility and a consistent experience for all users.
Network issues are inevitable, especially in real-time communication. Implement features like automatic reconnection or error messages to help users recover from network disruptions, similar to how Zoom or Facebook Messenger handle disruptions.
Building a video call app is a great way to provide value to your users, whether for personal or professional use. Agora SDK makes the process accessible, even for developers without much experience in real-time communication technology. By following the steps outlined above and using the features offered by Agora, you can create a video call app that is reliable, scalable, and cost-effective.
