# Android SDK

> **Warning**
>
> Ada has deprecated Chat. Messaging fully replaces Chat on December 15, 2026. Read [Introducing Messaging](https://docs.ada.cx/2026-09-30-introducing-messaging) to learn how to migrate.

This page covers the legacy Chat Android SDK. Follow the [Messaging Android upgrade guide](/messaging/android/getting-started#upgrade-from-the-existing-android-sdk) to migrate.

The Ada Android SDK makes it easy to embed Ada’s AI agent directly into your Android application. Designed for flexibility and customization, the SDK lets you programmatically control key settings and actions to deliver a tailored user experience.

Use the SDK to:
•	Embed Ada’s AI agent into your Android app seamlessly.
•	Customize the AI agent’s behavior with features like setting the language, defining initial greetings, and passing user-specific data via metaFields.

Explore all available settings and actions in the [Android SDK Reference](/chat/android/sdk-api-reference).

To get started, visit the [Android SDK Quick Start Guide](/chat/android/getting-started).

## Compatibility

The SDK supports Android 9 (Pie) and up.

## Known Limitations

**Session persistence across app restarts is not supported.** The SDK stores session state in the WebView's `localStorage`, which is not guaranteed to survive a force-quit on Android. See [Session Persistence](/chat/android/sdk-api-reference#session-persistence) for details.
