Use this guide when your Android app already has avatar speech audio and needs AvatarKit to send that audio to Motion Server, receive motion data, and render the avatar locally.

​
SDK package setup

Add the dependency to your build.gradle.kts:

Integration flow

1

Create credentials

Create an App ID and Avatar ID in Spatius Studio, then mint a Session Token from your backend. See Credentials.
2

Initialize AvatarKit

Initialize the Android SDK with your App ID, Avatar ID, Session Token, and selected region.
