Boots a clean Android emulator + Metro (Expo dev-client / bare React Native) with the right ordering: inspect existing IDE terminals first, kill stale ports/processes, choose "fresh cache wipe" vs "fast iteration" for Hot Reload, default to **1080×4000** display (tall QA default — gives maximum vertical space for full-screen screenshots in chat), adb reverse + poll Metro /status before deeplink to avoid connection races, and troubleshoot adb/Expo connectivity and white-screen. Use when asked to start Metro and emulator, restart dev loop, fix “Cannot connect to Expo”, spin up a new terminal instance, debug stuck bundler, or align emulator geometry for scroll QA. Generic for any app; repos may wrap these steps in package.json scripts.

From the source SKILL.md

Deliver a working dev loop (emulator online → tunnel → bundler ready → app intent) without burning time on duplicate Metros, stale caches, or racing the dev client ahead of /status.
