Prompting for Performance: Writing Butter-Smooth Jetpack Compose in the AI Era
Session
AI assistants can easily spit out 200 lines of flawless, compiling Jetpack Compose UI from a single prompt. It feels like magic—until you run it on a mid-range device, start scrolling, and hit massive jank.
The open secret of 2026? AI models are great at writing code that works, but notoriously bad at understanding the Jetpack Compose rendering pipeline. They pass raw state instead of lambdas and miss optimization tropes. Our jobs are shifting: we are no longer just code writers; we are performance auditors.
This talk shatters old optimization mindsets to view Compose performance through an AI-assisted lens. You'll learn:
AI Blindspots: How to spot LLM-generated recomposition traps in code reviews.
Bypassing Phases: Forcing AI to defer state reads using lambda modifiers to skip straight to the Drawing phase.
The Prompt Audit Loop: Feeding Perfetto traces and Macrobenchmark data back into AI for surgical fixes.
Stop fighting AI—learn how to audit it for butter-smooth UI.
