What problem does it solve?
This Skill helps you design and implement projected Android XR user interfaces for display glasses so they follow Jetpack Compose Glimmer’s additive-display and focus/interaction requirements instead of breaking legibility, contrast, or input behavior.
Core Features & Use Cases
- Glimmer-first UI rules for display glasses: Use GlimmerTheme and Glimmer components, avoid MaterialTheme/Material components, and enforce additive-display constraints like mandatory pure-black backgrounds.
- Correct font, typography, and readability guardrails: Require Google Sans Flex typography via createGoogleSansFlexTypography and enforce minimum readable text sizing (e.g., 0.6° / ~18sp).
- XR interaction and focus behavior: Map user inputs (tap/swipe) to glasses controls, use one-dimensional focus navigation patterns, and support initial focus on Glimmer focusable surfaces.
- Depth, hierarchy, and component styling: Use DepthEffect/DepthEffectLevels (via ShadowScope/Depth tokens) instead of Material 3 elevation, and apply surface/corner/spacing conventions for consistent visuals.
- System integration guidance: Integrate notifications/system UI behavior guidance into your Glimmer projected activity workflow.
Quick Start
Ask the AI to guide you to create a Glimmer-based projected activity for Android display glasses using GlimmerTheme + Google Sans Flex, with a pure black root background and Glimmer components that meet the minimum 18sp legibility requirement.
