 "page_title": "How to preview a React Native app on iOS and Android at once with Mobilecode",
 "summary": "Run one React Native project on both simulators from a single MobileCode session.",
 "who": "A mobile developer on a Mac with a React Native or Expo app who wants to see iOS and Android builds side by side while coding.",
 "problem": "Setting up Metro, simulators, emulators, and native builds for two platforms by hand is slow and easy to get wrong.",
 "outcome": "Both platforms run the same project in the device pane, with one shared Metro server.",
 "steps": [
  "Run `curl -fsSL https://raw.githubusercontent.com/hsandhu/mobilecode/main/install | bash` to install MobileCode.",
  "Open the React Native project folder as a session in MobileCode. Projects up to two directories below the session root are detected.",
  "Click Play on the iOS control in the session titlebar. The iOS simulator starts, the app builds, installs, and launches.",
  "Click Play on the Android control. The emulator starts and connects to the same Metro server that iOS already started.",
  "Use Stop on one platform to end only that run. Metro stays up while the other app is still running."
 ],
 "agent_prompt": "Using the MobileCode repo at https://github.com/hsandhu/mobilecode, start the iOS and Android previews for the React Native project at <project-path> through its device-preview HTTP endpoints (POST /api/device-preview/run with platform ios, then android). Report the run status for each platform. Before reporting success, confirm with GET /api/device-preview that both platforms show a running state.",
