Building a books app with Jetpack Compose and Firebase
summary
Builds an Android books app using Jetpack Compose for UI and Cloud Firestore for a serverless backend, with a LazyColumn list, Material cards and a floating action button that opens a simple add-activity form. Uses ViewModel + LiveData converted to Compose state, and a Firestore snapshot listener to sync changes in real time; initial demo shows three documents then adds new ones via add() (Firestore assigns random IDs). Covers set vs update semantics and it works live on device.
