Peer-to-Peer Sync on Android: Building Offline-First Apps That Talk to Each Other

In a world obsessed with cloud connectivity, what if your app could sync data directly with nearby devices, without hitting the cloud? This session introduces peer-to-peer (P2P) sync patterns for Android that enable apps to share data over LAN, Wi-Fi Direct, or BLE. We’ll walk through building resilient, offline-first apps where data flows between devices securely and automatically, perfect for field deployments, disaster zones, or privacy-focused use cases.
Whether you’re building a logistics tool, health records app, or multiplayer experience. This talk will show you how to build apps that sync serverlessly!
Towards the end, I will also showcase a very futuristic idea, where we will be using mesh topology to text offline just like WhatsApp.
