From the author

Provides instructions and workflows for accessing and managing hardware on Android XR projected devices, such as audio glasses and display glasses. Use this skill when building experiences for intelligent eyewear in an Android app and you need to access device hardware like the camera and microphone, handle glasses-specific runtime permissions, or manage connection lifecycles using projected context.

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides the necessary patterns for Android developers to interact with hardware components on connected XR devices, such as audio and display glasses. It focuses on the use of ProjectedContext to manage device lifecycles, handle hardware-specific permissions, and ensure stable connections between the host phone and the wearable hardware.

What it does

  • Explains how to obtain and use a ProjectedContext for hardware access.
  • Provides patterns for monitoring connection states between the host phone and XR glasses.
  • Outlines the requirements for declaring and requesting runtime permissions for glasses hardware.
  • Details how to manage resource lifecycles based on device availability and connection status.
  • Offers guidance on integrating with system services like CameraManager for glasses-specific hardware.

When to use it

  • When developing Android applications that need to access cameras or microphones on connected XR eyewear.
  • When you need to implement robust connection monitoring to handle device disconnects or removal.
  • When you need to manage runtime permissions specifically for projected XR hardware.
  • When your app needs to distinguish between phone-based hardware and connected glasses-based hardware.

Advantages

  • Ensures stable hardware interaction by leveraging the official ProjectedContext lifecycle management.
  • Provides clear patterns for handling the dynamic nature of wearable device connectivity.
  • Helps developers correctly implement Android runtime permissions for XR-specific hardware.

Usage examples

“How do I access the camera on connected audio glasses in my Android app?”
The skill provides the implementation pattern using ProjectedContext to initialize system services like CameraManager specifically for the connected glasses.
“How can I tell if the user is currently wearing their display glasses?”
The skill explains how to use the XR Device Availability API to monitor Lifecycle.State and determine if the device is active, inactive, or disconnected.

Install

Prerequisites

  • You must use a compileSdk of 36 or higher.

Connection and lifecycle management

Intelligent eyewear hardware is only accessible while the glasses are connected to the host phone. Monitor connection state and manage resource lifecycles using ProjectedContext. You must read Understand projected activities and projected contexts to understand how to get a projected context and how to manage its lifecycle.

Request glasses hardware permissions

  • Hardware permissions and opt-in : You must read Request hardware permissions to understand how to declare camera and microphone runtime permissions in the Android Manifest file, request runtime permissions in different scenarios, and handle permission results.
