An Android instant messaging (IM) client library built on Netty, TCP, and Protobuf. It provides a complete long-connection messaging stack including Protobuf serialization, TCP packet splitting/sticky-packet handling, handshake authentication, heartbeat, reconnection, message resending, read/write timeouts, offline messages, and thread pooling.
Use cases
- add chat messaging to an Android app
- implement a reliable TCP long connection on Android
- send and receive protobuf messages over a persistent socket
- handle heartbeat and automatic reconnection for mobile IM
- deliver offline messages when users reconnect
- learn how Netty-based IM clients handle sticky packets and handshakes
When to choose
- you need a self-hosted, protocol-level IM client on Android with full control over the wire protocol
- you want TCP reliability with protobuf efficiency for high-volume messaging
- you want a learning reference for building Netty-based Android IM systems
When to avoid
- you need a turnkey chat backend with accounts, groups, and push - this is a client-side transport library only
- you prefer WebSocket or MQTT-based messaging instead of raw TCP
- you need an actively maintained library with recent releases (last release 2020)
- your project is not on the JVM/Android
