What problem does it solve? Building UI for display glasses is fundamentally different from phone apps: additive displays render black as transparent, standard Material components become invisible, and input is one-dimensional via a touchpad. This Skill guides you through creating projected Android XR experiences that follow the Glimmer design system so your app is legible and usable on eyewear. ## Core Features & Use Cases - Projected Activity Setup: Configure a Glasses Activity with ProjectedContext, xr_projected display category, and a "Launch on Glasses" entry point from an existing mobile app. - Glimmer Component Implementation: Build Cards, Buttons, Title Chips, Icons, Lists, Stacks, Text, and Surfaces with correct theming via GlimmerTheme, backed by API source code and sample references. - Design Constraint Enforcement: Apply mandatory rules such as pure black backgrounds, Google Sans Flex typography with variable font axes, 18sp minimum text size, 70% HCT color contrast, and depth effects via DepthEffectLevels. - Use Case: You have an existing Android app and want to extend it to display glasses. The Skill walks you through adding the Glimmer dependency, creating a projected activity, and building a bottom-aligned card UI that works with the glasses touchpad. ## Quick Start Use the display-glasses-with-jetpack-compose-glimmer skill to add a Glimmer-based glasses activity to my Android project with a card list UI.
