Connect your Android Things with Firebase
summary
Prototype builds a video doorbell on Android Things and actually works end to end: camera captures images, uploads to Cloud Storage, Firestore, Cloud Functions, Cloud Messaging, app receives FCM topic notifications, displays image via Glide and Firebase UI, homeowner responds and Cloud Functions notifies the device. Setup uses nearby connections token transfer to deliver a Google auth token to the device. Watch for camera API quirks, topic security limits, and insecure default Firebase rules that need tightening.
