UI Kit Builder Settings

The CometChatBuilderSettings object controls everything the Android UI Kit Builder renders—messaging, AI helpers, calls, layout, theming, and more. This object is auto-generated by the UI Kit Builder Settings Gradle plugin from your cometchat-builder-settings.json configuration file.

For developers customizing their chat UI: The CometChatBuilderSettings.kt file is generated automatically when you build your project. Edit the cometchat-builder-settings.json file to enable/disable features like messaging, calls, AI copilot, and theming. See the Integration Guide for setup.

Top-level Structure

The generated CometChatBuilderSettings object in Kotlin follows this structure:

object CometChatBuilderSettings {
    object ChatFeatures {
        object CoreMessagingExperience { /* Boolean constants */ }
        object DeeperUserEngagement { /* Boolean constants */ }
        object AiUserCopilot { /* Boolean constants */ }
        object UserManagement { /* Boolean constants */ }
        object GroupManagement { /* Boolean constants */ }
        object ModeratorControls { /* Boolean constants */ }
        object PrivateMessagingWithinGroups { /* Boolean constants */ }
        object InAppSounds { /* Boolean constants */ }
    }
    object CallFeatures {
        object VoiceAndVideoCalling { /* Boolean constants */ }
    }
    object Layout { /* Layout constants */ }
    object Style {
        object Color { /* Color constants */ }
        object Typography { /* Typography constants */ }
    }
}

All boolean settings follow the same pattern: true enables the feature and shows its UI elements, false hides them completely.
