🧠 Key Concepts

Understand the core components of our SDK:

• Meeting - A Meeting represents Real-time audio and video communication.

  Note: Don't confuse the terms Room and Meeting; both mean the same thing 😃

• Sessions - A particular duration you spend in a given meeting is referred as a session, you can have multiple sessions of a specific meetingId.

• Participant - A participant refers to anyone attending the meeting session. The local participant represents yourself (You), while all other attendees are considered remote participants.

• Stream - A stream refers to video or audio media content published by either the local participant or remote participants.

🔐 Token Generation

The token is used to create and validate a meeting using API and also initialize a meeting.

🛠️ Development Environment:

• You may use a temporary token for development. To create a temporary token, go to VideoSDK's dashboard .

🌐 Production Environment:

• You must set up an authentication server to authorize users for production. To set up an authentication server, please take a look at our official example repositories. videosdk-rtc-api-server-examples

🧩 Project Overview

App Behaviour with Different Meeting Types

• One-to-One meeting - The One-to-One meeting allows 2 participants to join a meeting in the app.

• Group Meeting - The Group meeting allows any number of participants to join a meeting in the app.

🏗️ Project Structure

• We have created 3 package screens and widgets in the following folder structure:
  • OneToOneCall - It includes all classes/files related to OneToOne meetings.
  • GroupCall - It includes all classes/files related to the Group meetings.
  • Common - It includes all the classes/files that are used in both meeting type.

Common package

1. Pre-Call Setup on Join Screen

• DeviceAdapter.java : This is a custom RecyclerView.Adapter used to display a list of audio devices. It takes a list of devices and a click listener to handle item clicks. Each item shows the device name and an icon.

• bottom_sheet.xml : This layout defines the structure of the bottom sheet dialog, which contains a RecyclerView that displays the list of items. The RecyclerView fills the available space and references list_items_bottom_sheet for its individual list items.

• list_items_bottom_sheet.xml : This layout defines how each item in the bottom sheet looks. It contains a LinearLayout with an ImageView for the device icon, a TextView for the device label, and another ImageView for a checkmark icon. The checkmark is used to indicate the currently selected device.

2. Create or Join Meeting

• NetworkUtils.java - This class is used to call the API to generate a token, create and validate the meeting.

• CreateOrJoinActivity.java and activity_create_or_join.xml : This Activity allows users to either create or join a meeting. It manages microphone and webcam permissions and handles UI interactions like enabling/disabling audio and video. It also switches between the CreateMeetingFragment and JoinMeetingFragment, depending on user actions.

• CreateOrJoinFragment.java and fragment_createorjoin.xml : This fragment provides two buttons for users to either create or join a meeting. On button clicks, it transitions to the respective fragments (CreateMeetingFragment or JoinMeetingFragment) within CreateOrJoinActivity.

• CreateMeetingFragment.java and fragment_create_meeting.xml : This fragment enables users to create a new meeting by selecting a meeting type (e.g., One-to-One or Group Call) and entering their name. Upon submission, it makes a network request to create a meeting and navigates to the relevant meeting activity.

• JoinMeetingFragment.java and fragment_join_meeting.xml : This fragment allows users to join an existing meeting by entering a valid meeting ID and their name. It validates input and, on success, navigates to the appropriate meeting activity based on the selected meeting type.

3. Switch AudioDevice

• AudioDeviceListAdapter.java : This is a custom ArrayAdapter that displays a list of audio devices in a dialog. It uses a ListItem model to represent each audio device. The layout for each list item is defined in audio_device_list_layout.xml.

• ListItem.java : This class represents an individual list item (audio device) with properties such as the device name, icon, and a description, and a boolean indicating whether the item is selected.

• audio_device_list_layout.xml : This layout defines the appearance of each audio device in the list.

4. Chat

• MessageAdapter.java ; This is a custom RecyclerView.Adapter for displaying chat messages in a meeting.

• item_message_list.xml : This layout defines the structure of each chat message in the list. It displays the sender's name, the message, and the message timestamp.

5. ParticipantList

• ParticipantListAdapter.java : This adapter displays the list of meeting participants in a RecyclerView. It includes the local user and updates in real-time as participants join or leave the meeting.

• layout_participants_list_view.xml : This layout defines the structure for the participant's list view. It includes a RecyclerView that lists each participant using the item_participant_list_layout.

• item_participant_list_layout.xml : This layout defines the appearance of each participant in the list. It displays the participant’s name, microphone, and camera status.

OneToOneCall package

• OneToOneCallActivity.java : OneToOneCallActivity.java handles one-on-one video call, providing features like microphone and camera control, screen sharing, and participant management. It supports real-time chat and meeting event listeners for tasks like recording and screen sharing. The activity also displays session elapsed time and handles permissions for audio, video, and screen sharing.

GroupCall package

• GroupCallActivity.java : The GroupCallActivity class manages the main UI and logic for initiating and maintaining a group video call. It serves as the primary activity where users can join a video call session, toggle mic and camera. It also manages the video grid where all participants are displayed using ParticipantViewFragment and ParticipantViewAdapter.
• ParticipantViewFragment.java : Displays an individual participant's video feed and controls within a fragment, updating the UI based on participant state changes.
• ParticipantViewAdapter.java : Binds participant data to a RecyclerView, dynamically updating the video grid as participants join, leave, or change state.
• ParticipantChangeListener.java : Listens for participant-related events (join, leave, state changes) and triggers UI updates.
• ParticipantState.java : Represents the current state of a participant, such as mute and video status, for UI display and logic handling.
