Android UI Kit

The Android UI Kit enables you to integrate a complete, production-ready video call interface into your Android native app with just a few lines of code. The framework is 100% native, handles auto-orientation, and provides 99% reduced development time compared to building from scratch using the raw Android SDK.

Rather than managing streams, media devices, and UI controls individually, you drop in a single EnxVideoView component. It renders the full video session experience — participant tiles, toolbar controls, chat, screen share, and more — and exposes a clean observer interface for lifecycle events.

The UI Kit ships with a comprehensive set of in-session controls available to all participants, with an additional layer of moderator-only capabilities for session management.

Features for Participants and Moderators

Every user in a session — regardless of role — has access to the following controls:

• Mute and unmute their own audio and video
• Switch between front and rear cameras
• Switch audio output device (speaker, earpiece, or Bluetooth)
• Group and private text chat
• File sharing with all participants or privately with an individual
• View and configure the participant list
• Switch video layout
• Raise hand to request floor access (Lecture and Webinar modes)
• Annotate on a shared screen
• Screen sharing
• Canvas streaming
• Disconnect call
• Picture-in-Picture (PiP) mode for seamless multitasking
• Audio-only call UI — improved calling screen for 1-to-1 audio calls with overlay mic and exit controls

Features for Moderators Only

Users who join with the moderator role get additional in-session controls for managing the session and participants:

• Record the session
• Hard mute the entire room audio
• Mute or unmute an individual participant's audio or video
• Drop a participant from the room
• Grant or deny floor access requests (Lecture mode)
• Revoke previously granted floor access (Lecture mode)
• Start and stop RTMP live streaming

v2.2.2 introduces an improved UI for 1-to-1 audio-only calls. When a participant joins without video, the kit renders a purpose-built calling screen showing the remote participant's name and avatar over a gradient background, with overlay buttons for microphone toggle and exit. This replaces the generic video grid with an experience designed specifically for voice calls.

Enable the Audio View Overlay

Call isAudioViewMode(false) on the EnxSetting singleton to activate the audio call UI with overlay mic-toggle and exit controls:

EnxSetting.getInstance(this).isAudioViewMode(false);

Customise the Audio View Appearance

Use configureAudioViewConfig() with an EnxAudioViewConfig object to define the visual appearance of the audio call screen. All colour properties accept standard Android Color values:

EnxSetting.getInstance(this).configureAudioViewConfig(
    new EnxAudioViewConfig(
        Color.parseColor("#0A3733"),   // gradientLayer1   — top gradient colour
        Color.parseColor("#031412"),   // gradientLayer2   — bottom gradient colour
        Color.WHITE,                   // nameTextColor    — remote participant name
        Color.WHITE,                   // sortNameTextColor — initials text colour
        Color.parseColor("#128C7E")    // sortNameBGColor  — initials avatar background
    )
);
