kcptun for Android

kcptun for Android is an Android plugin that brings kcptun acceleration support to the Shadowsocks Android ecosystem. It is designed as a SIP003 plugin, which means it can be used alongside shadowsocks-android rather than functioning as a standalone VPN client. The project packages kcptun client functionality for Android users who want to route Shadowsocks traffic through a KCP-based transport layer. Its main purpose is to improve connection behavior in unstable or high-latency network conditions by using kcptun’s reliable UDP tunneling approach. The repository includes Android application code, plugin integration files, and localization support through the same translation process used by shadowsocks-android. It is best understood as a specialized networking companion for users who already understand Shadowsocks and kcptun configuration.
