Joining Multiple Channels Using the Agora Android SDK

This tutorial guides developers through adding real-time engagement (RTE) functionality to their Android applications using the Agora RTE SDK, without needing to manage servers or load balancing. The process involves subscribing to multiple channels for tracking activities of different groups and includes setting up a sample project in Android Studio, creating a login page that reads two channels, designing a video calling layout, and building the final calling page. The tutorial also covers testing the application before deployment.
