Getting Started

This sample shows how to host one publisher (your camera) and multiple remote participants in the same Vonage Video session.

This sample has three main parts working together:

1. Session handling (MainActivity) — Creates the video session, sets up one local publisher, and creates a subscriber for each remote participant.

2. UI state management — Uses mutableStateOf and mutableStateListOf to track UI changes, such as mic/camera on or off, whether a slot is occupied, and whether remote audio is enabled.

3. Compose UI (SimpleMultipartyScreen) — Displays participants in a grid where each slot stays in the same position. The local video preview appears as a small overlay, and bottom controls let users switch cameras and toggle audio/video.
