The most exciting shift in the Android ecosystem isn’t happening on a phone; it’s happening in the space around us. But how do you bridge the gap between Jetpack Compose and Mixed Reality without losing your architectural integrity? This session is a deep dive into Cross/Multi-platform Development using the PICO Spatial SDK. We’re moving beyond traditional 2D UI to explore how Advanced Kotlin and Jetpack Architecture Components function when a Z-axis is introduced. We will dissect the "spatialization" of native Android apps, focusing on maintaining clean MVI/MVVM patterns across multitasking environments, and how AI can help reduce development time. What we will cover: Jetpack Compose in 3D: Leveraging existing Compose skills to build responsive, anchored Spatial UI. Architecture & State: Managing lifecycle and state using Architecture Components in a Shared Space environment. UI/UX/Design: Implementing "Look and Pinch" interaction models via standard Android Input Listeners. Testing & Infrastructure: Using the PICO Emulator to build automated UI tests for spatial environments within your existing CI/CD pipeline. Career & Leveling Up: Why "Spatial Architect" is the logical evolution for senior Android Engineers in 2026.
