Creating Applications for Small Screen, Low Memory Android Wearables
summary
AOSP wearable prototype (WS50) with 1 GB RAM and 8 GB flash, 2" touch display, NFC, Wi‑Fi and Bluetooth but no cellular, hot‑swap battery and integrated scanners demonstrates constraints: keep each screen to a single, critical task, minimize background processes, avoid wake locks, test Doze handling, and use sensors in batch mode to save power and memory. MIT data drives touch targets for 8–10 mm fingertips and workflows are optimized to complete tasks in <30s for useful wrist UX.
