Won’t You Be My Neighbor? Making Friends with Google Nearby

on YouTube ↗43m

" summary

Google Nearby is usable here via Google Play services using the Nearby Messages API, Gson and base64 images; the workshop builds a working app called NerdAlert (APK on GitHub) that publishes and subscribes peer‑to‑peer over Bluetooth/BLE Wi‑Fi and ultrasound. Messages hit practical limits — roughly 10 kilobytes payload, TTL defaults to 5 minutes (max ~1 day), and an earshot (~3–4 ft) mode uses ultrasound. Requires API keys, user opt‑in, internet for auth, foreground activity and costs ~3–4× more battery, but the demo runs.
