Based on Nekogram. Key additions: - Rebrand to FoxiGram (app name, APK name, applicationId com.foxigram.app) - Embedded Xray (VLESS+Reality) proxy client via JNI libxray.so - Bundled hidden one-tap proxies (LTE + WiFi), read-only in UI - Auto-restore proxy on restart, rebind to active network (LTE/WiFi) - Server credentials externalized to git-ignored XrayServers.java (+ template) - libxray Go source included; compiled .so, keystore, google-services.json ignored
