Hello, I can upgrade and modernize your existing ICS OpenVPN based Android VPN app and ensure full compatibility with the latest Android versions, including 16KB memory page size requirements. I will start by updating the Gradle build system, dependencies, and Android SDK configurations to bring the project up to current standards while fixing all deprecated APIs and build issues. I will handle the native layer carefully by rebuilding and validating the .so libraries using Android NDK to ensure stable VPN functionality across modern devices. I will also fix VPNService implementation issues to ensure reliable connection handling, background stability, and proper lifecycle management on newer Android versions. Finally, I will generate a fully working signed APK and AAB, thoroughly tested to confirm VPN connectivity, stability, and compliance with current Play Store requirements. I am experienced with legacy Android migrations and NDK-based VPN applications and can complete this upgrade efficiently with a focus on stability and compatibility.

Hi, I’ve worked with similar VPN apps and already solved 16KB page size compatibility issues for Android. I can upgrade your ICS OpenVPN project, fix Gradle/build issues, update deprecated APIs, rebuild native libraries, and ensure the VPN works properly on latest Android versions. I also have experience with Android NDK, VPNService API, and generating release-ready APK/AAB builds. Can you share the source code so I can review and estimate the timeline?

@iAmiteshKr

Hi there, As its open end requirement, i can start with kickoff payment. Below are points for consideration: Deep VPN & Networking Expertise: I have 15+ years of experience in network programming and protocol implementation, including hands-on work with TCP/IP stacks, DNS (DoH, DoT, DoQ), and firewall/load balancer development. Android & Kotlin Skills: i have specifically developed Android applications using Kotlin and RFComm sockets, showing you can handle the mobile-specific aspects of this upgrade. Security & Performance: The project requires memory optimization and "untraceable" features. mastery of Rust (known for memory safety/performance) and advanced cryptography (OpenSSL, Noise protocol, WireGuard-related concepts) is a significant advantage for optimizing VPN throughput and privacy. Basic UI : i have basic ui based app development experience as i am system developer. Question : let me know you have ready made setup or setup is part of deliverables ?

Dear Client, I understand you already have an existing VPN application based on **ICS OpenVPN**, but the project now faces compatibility and stability issues with newer Android versions and modern device architectures. Legacy VPN projects often break because of outdated Gradle configurations, deprecated Android APIs, incompatible native libraries, and newer Android security restrictions. I will upgrade and modernize your existing Android VPN project by updating the Gradle environment, SDK targets, dependencies, and deprecated APIs while preserving the core VPN functionality. I will rebuild and optimize the native OpenVPN libraries using Android NDK for compatibility with current Android versions and 16 KB page size devices. I have experience working with **Android Studio, Java/Kotlin applications, Android NDK, native `.so` libraries, Gradle migrations, and VPN-based Android projects** involving legacy code modernization and compatibility fixes. My focus is on delivering stable, production-ready builds while ensuring performance, compatibility, and clean architecture throughout the upgrade process. best regards Habib Ullah

Hi, I have worked on Android NDK projects and legacy upgrades extensively, and I have successfully published multiple apps after the 16 KB page size transition, so I know exactly what this project requires. Here is what I will handle: Gradle migration to the latest AGP version with all dependency conflicts resolved. Deprecated API fixes across Java and Kotlin layers. Native library rebuild and alignment for 16 KB memory page size compatibility, which is the most critical and technical part of this work. VPNService integration verified against the latest Android versions. Full build producing a working APK and AAB ready for Play Store submission. On the 16 KB side specifically, this requires ensuring all .so files are compiled with the correct alignment flags and that the NDK build configuration is updated properly. I have done this on live published apps so there will be no guesswork. I will review your existing source code first and give you a clear picture of the issues before any work begins, so you know the exact scope upfront. Timeline: 5 to 7 days depending on the current state of the codebase. I am ready to start immediately. Share the project and I can give you a precise assessment within 24 hours.
