🚀 Overview

The Android OVPN Client based on OpenVPN is a full-source Android application template that uses the proven OpenVPN protocol to create a mobile VPN client. It supports importing `.ovpn` profiles, secure tunneling via Android’s VPNService API, and offers a foundation for building branded VPN apps for Android devices.

Developers, VPN service providers, network admins and mobile-app publishers will find this solution ideal for launching their own Android VPN client, integrating with existing VPN servers, or reskinning and monetising a VPN app with full control over the source code.

⚙️ Technical Stack

• Platform: Android (Java/Kotlin) — template may use Java or Kotlin depending on version.
• VPN Engine: OpenVPN protocol libraries (via open-source project e.g., OpenVPN for Android – GitHub by Arne Schwabe). :contentReference[oaicite:4]{index=4}
• Build Tools: Android Studio (Gradle), minimum Android SDK level e.g., API 21+ (Android 5.0+). The CodeCanyon listing references “Compatible with Android 5.0 and above”. :contentReference[oaicite:5]{index=5}
• Dependencies: Android-VPNService API, OpenSSL or BoringSSL, LibOpenVPN or wrapper, UI libraries (Material Components, RecyclerView) and possibly remote config (Firebase or REST backend).
• Server/Backend Requirements (optional): If you provide server list or subscription backend: HTTPS server, REST API, payment gateway integration, certificate generation for OpenVPN server side.

🧩 Installation Guide

1. Download the full source-code package (Android project) from the marketplace. :contentReference[oaicite:6]{index=6}
2. Open the project in Android Studio and sync Gradle — ensure SDK 21+ and latest build tools.
3. Configure your branding: adjust `app_name`, icons, colours, themes, and version info.
4. Configure server profiles: populate your `.ovpn` files or remote config endpoint for servers, certificates and keys.
5. Test on an Android device/emulator: import profile, connect to OpenVPN server, verify tunnel, traffic routing and stats view.
6. Build & Publish: Generate signed APK/AAB, prepare store listing, privacy policy (VPN usage), and publish to Google Play or sideload as needed.

🧠 Notes

Licensing & Compliance: Because the app uses the OpenVPN open-source libraries (GPL licensed), if you distribute your version you must comply with GPL terms: publish source or make it available, keep original license notices. The listing “Android OVPN Client based on OpenVPN” notes “Source code obfuscation” and use of OpenVPN protocol which is open-source. :contentReference[oaicite:10]{index=10}

Security & Privacy: As you are building/publishing a VPN client, you must ensure secure certificate handling, proper socket tunnelling, data leak prevention (IPv6 leak, DNS leak), and clear privacy policy for end users.

Customization Tips:

• Support remote server list fetching via Firebase or your backend for dynamic server updates.
• Add dark mode, analytics (cold start not intrusive), referral mechanisms and premium/subscription gating if you monetise.
• Localise UI into key markets (e.g., Bengali for Bangladesh, Hindi for India) and adapt payment gateways (bKash, Nagad, Paytm) if selling services in South Asia.
