The LEAP Edge SDK provides native Kotlin integration for deploying LFM2 models on Android devices. The SDK handles model loading, inference, and streaming responses, making it straightforward to add on-device AI capabilities to your Android applications.

​
Android examples

The following examples demonstrate different use cases and capabilities of the LEAP SDK on Android:

LeapChat

Full-featured chat app with real-time streaming, persistent conversation history, and modern Android UI

LeapAudioDemo

Audio input and output processing with LFM2.5-Audio-1.5B for voice-enabled AI features

LeapKoogAgent

Integration with the Koog framework for building AI agents with tool calling capabilities

SloganApp

Single-turn marketing slogan generation demonstrating Android Views integration

ShareAI

Website summary generator that processes shared URLs

Recipe Generator

Getting started

All Android examples are available in the LeapSDK-Examples repository. Each example includes:
  • Complete source code with Kotlin implementation
  • Gradle build configuration
  • README with setup instructions
  • Sample prompts and usage examples

​
Installation

  1. Clone the LeapSDK-Examples repository: 
    git clone https://github.com/Liquid4All/LeapSDK-Examples.git
cd LeapSDK-Examples/Android
  2. Open the example project in Android Studio
  3. Follow the example-specific README for model setup and configuration

​
Basic integration

The LEAP SDK makes it easy to integrate LFM models into your Android app. Here’s a basic example: 
import ai.liquid.leap.LeapSDK

val sdk = LeapSDK.getInstance(context)
sdk.loadModel("lfm2-1.2b-instruct")

sdk.generateStream("Tell me a story") { token ->
    // Handle streaming tokens
    runOnUiThread {
        textView.append(token)
    }
}
