iv B4a Tool 🛠️

Build VPN apps in B4A. Skip the native code part.

If you've ever tried adding a VPN core to a B4A project, you know how it goes. Java wrappers, .so files, Gradle stuff B4A doesn't even let you touch. Hours gone, and the thing still won't compile.

That's why I made this tool. Open your project, pick what you want, build. Done.

What's inside 📦

🌐 V2Ray Core 1.9.0
Full core injected into your project. VMess, VLESS, Trojan, Shadowsocks. All working out of the box.

🔒 OpenVPN3
Need .ovpn support? Add it in one click. Use it on its own or together with V2Ray.

💰 Appodeal SDK
Ads ready to go, so your app can actually make money.

📱 APK & App Bundle
Signed APK for direct downloads, or AAB if you're publishing on Google Play.

The good part ✨

No manifest editing. No permission hunting. No dependency conflicts at 2 AM. The tool sets everything up so your project just builds.

Who it's for 👨‍💻

B4A developers making VPN clients, proxy apps, or anything that needs a tunnel. Whether it's your first app or your tenth.
