Official Android SDK for Stream Chat

This is the official Android SDK for Stream Chat, a service for building chat and messaging applications. This library includes both a low-level chat SDK and a set of reusable UI components. Most users start with the UI components, and fall back to the lower level API when they want to customize things.

The SDK supports both Kotlin and Java, but we strongly recommend using Kotlin.
