Implementing Video Call Functionality in Android App

1. Understanding Video Call Integration:

Client-Server Model: Video calling relies on a client-server model. The client app on user devices handles capturing video/audio, while the server facilitates communication and data exchange between clients.

2. Choosing the Right SDK:

Third-party SDKs: Leverage established Video Calling SDKs offered by companies like Agora, Twilio, or Sinch. These SDKs provide pre-built features and APIs, simplifying development and handling complexities like audio/video streaming, security, and network management.

Factors to Consider: Evaluate features, documentation quality, pricing, and scalability of the SDK based on your project's specific needs.

3. Setting Up the Development Environment:

Android Studio: Use Android Studio as your Integrated Development Environment (IDE) for building the Android app.

Development Tools: Familiarize yourself with the Android SDK and relevant libraries for handling multimedia functionalities.

4. Implementing Video Call UI Components:

Layouts: Design user interfaces for video call screens, including elements like video previews for local and remote users, call controls (mute, end call), and chat options (if applicable).

Permissions: Request necessary permissions from the user to access camera and microphone for video calling.

5. Integrating Video Call APIs:

SDK Integration: Follow the chosen SDK's instructions to initialize it within your app.

Connection and Call Management: Use the SDK's APIs to establish connections with the communication server, initiate calls, handle incoming calls, and manage the video call session.
