android-glasses

Extentos Android SDK — smart-glasses capabilities for any Android app.

Camera capture, voice triggers, live transcription, audio playback and on-glasses display, from your existing Android app. Works with Meta smart glasses today (Ray-Ban Meta, Oakley Meta, Meta Ray-Ban Display), with a multi-vendor architecture by design.

Why this repo has no source

The SDK is distributed through Maven Central, which needs no GitHub repository to publish or consume. Its iOS counterpart, swift-glasses, exists only because SwiftPM requires a package manifest at a repository root. Gradle has no such requirement, so there was never an Android equivalent to create.

This repo is the Android SDK's public home: install instructions, module map, and issues.

Install

// build.gradle.kts
dependencies {
    implementation("com.extentos:glasses:2.5.0")       // core SDK
    implementation("com.extentos:glasses-ui:2.5.0")     // connection UI (optional)
    implementation("com.extentos:glasses-meta:2.5.0")   // Meta vendor transport
}

The badge above is authoritative for the current version. Android and iOS release in lockstep off one shared Rust core, so both platforms always carry the same version number.

The vendor module is required. As of 2.0.0 com.extentos:glasses is vendor-agnostic and contains no Meta code. Without com.extentos:glasses-meta on the classpath the camera silently has no transport.

Modules

Module	What it is
glasses	Core SDK: connection, camera, audio, display, toggles, telemetry
glasses-ui	Jetpack Compose connection page
glasses-meta	Meta transport — Ray-Ban Meta, Oakley Meta, Meta Ray-Ban Display
glasses-brilliant	Brilliant Labs transport (preview, not hardware-verified)
glasses-local	On-device model tier
glasses-local-voice	On-device TTS

Requires minSdk 31 and compileSdk 35.

Getting started

The fastest path is to let your coding agent do the integration. It discovers the SDK surface, scaffolds the connection module, and verifies the result in a browser simulator that runs the same SDK code as production, so you can build and test the glasses flow without owning hardware.
