 We’re excited to share this Android demo app using both remote and local Llama Stack features! The primary goal of this app is to showcase how to easily build Android apps with Llama models using Llama Stack SDKs in a chat app setup.
 
 This app serves as a valuable resource to inspire your creativity and provide foundational code that you can customize and adapt for your particular use case.
 
 Please dive in and start exploring our demo app today! We look forward to any feedback and are excited to see your innovative ideas to build agentic apps with Llama models. The current demo app is built using both Java and Kotlin. The majority of the activities are built with Java but the interfacing with Llama Stack APIs are in Kotlin.
