projected-hardware

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.

## 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](references/android/develop/xr/jetpack-xr-sdk/glasses/support-different-types.md) to understand
how to get a projected context and [how to manage its lifecycle](references/android/develop/xr/jetpack-xr-sdk/glasses/check-availability.md).
