> This page indexes focused, task‑oriented feature guides for the Android UI Kit. Each guide shows how to implement a specific capability end‑to‑end using UIKit components. Guides include both **Kotlin (XML Views)** and **Jetpack Compose** examples where applicable.
## When to Use These Guides
Use these guides after completing the base [Getting Started](/ui-kit/android/v6/getting-started) setup. They help you layer additional UX without rewriting core chat flows.
The CometChat Android UI Kit is available in two modules:
| Module | Description |
| :------------------ | :----------------------------------------------------------------- |
| `chatuikit-kotlin` | Traditional XML-based Views for use with Activities and Fragments. |
| `chatuikit-jetpack` | Jetpack Compose components for declarative UI. |
