v2ray_box changelog | Flutter package

1.0.4 - 2026-02-23 #

Android: fixed stale ping loading state after app background/close; ping sessions are now canceled reliably and transient loading states are not persisted.
Android: improved core switch/start lifecycle (xray/sing-box) to force clean stop before restart and avoid broken first-connect states.
Android: improved xray disconnect responsiveness by closing TUN immediately and bounding core shutdown wait.
Android: hardened sing-box process restart/stop flow to avoid stale process issues after repeated engine switches.
Example (Android): added Proxy mode endpoint helper card with core-specific local addresses, copy action, and local listener test button.
Example (Android): fixed Proxy helper layout overflow on small screens.

Android: improved sing-box config generation (DNS/route defaults, transport normalization, domain resolver handling) for better compatibility with V2Ray links.
Android: fixed sing-box "connected but no traffic" scenarios by using stable direct DNS fallback and waiting for sing-box inbound readiness before starting the VPN bridge.
Android: optimized ping implementation with bounded parallelism and timeout controls; added default timeout 7000ms for ping and pingAll (optional override).
Android: improved Xray outbound normalization and transport/TLS parsing consistency for legacy/partial links.
Docs/example: updated ping timeout usage and default ping URL to https://www.gstatic.com/generate_204.

Docs: added required Android manifest permissions/services used by the example app.
Docs: unified Android Gradle settings into a single section to avoid duplicated setup steps.

Android: improved Xray/Sing-box config normalization for V2Ray links with empty or legacy query fields.
Android: fixed VLESS/VMess/Trojan handling for tcp + headerType=http, TLS/Reality defaults, and SNI fallback behavior.
Android: improved gRPC and insecure flag parsing compatibility (allowInsecure / insecure).
Android: reduced VPN TUN MTU from 9000 to 1500 for better mobile network stability.
