Sync Data with your Mobile Kotlin App The Easy Way!
summary
A Kotlin sample app uses MongoDB Atlas Device Sync (Realm SDK) to provide birectional real‑time sync with a cloud Atlas cluster, a local ACID object store, and automatic offline queuing so writes persist locally and push when online. The demo builds a simple task tracker, uses generated JSON schema and one‑click Kotlin model code, calls copyToRealm to persist objects, and shows automatic schema updates in dev mode plus conflict rules (operational transform, delete wins, last‑update‑wins, Lamport ordering) that resolve edits correctly.
