Hysteria 2 Android client, built directly on the protocol core

What it does The full Hysteria 2 configuration: authentication, TLS (custom SNI, custom CA, certificate pinning, mutual TLS), Salamander and Gecko obfuscation, QUIC window and timeout tuning, BBR and Brutal congestion control, bandwidth limits, and port hopping with configurable intervals. Realm rendezvous mode: connect to a peer behind NAT through STUN and UDP hole punching by giving a realm:// address, no public IP or port forwarding required. A real TUN device backed by a gVisor userspace stack, carrying both TCP and UDP. DNS resolves through the tunnel and is cached, so other apps need no proxy settings. Import straight from hysteria2:// and hy2:// links. Per-app allow and block lists, and rule-based split tunnelling. Reconnects on its own: QUIC keep-alive, a watchdog that probes a stalled tunnel and re-resolves the server address, and an immediate re-dial when the network switches between Wi-Fi and mobile. A Quick Settings tile, always-on VPN support, and a foreground service that holds up under aggressive battery management
