The objective is to create a fully offline file-sharing application that forms an ad-hoc, multi-hop mesh network and runs natively on both Android and iOS. Devices should discover one another automatically, relay files even when they are not in direct range, and keep transfers alive as phones move through the topology. No internet connection, central server, or cellular data may be required at any point; every packet must flow peer-to-peer until it reaches its destination. Core scope • Build separate native clients (Kotlin/Java for Android, Swift/SwiftUI for iOS) or use a cross-platform framework if it can still leverage each OS’s low-level mesh APIs (Wi-Fi Aware, Wi-Fi Direct, Bluetooth LE, Multipeer Connectivity, etc.). • Implement routing that supports at least three hops in practical tests, automatically re-routing around dropped nodes. • Transfer any standard file type while maintaining original metadata and folder structure where applicable. • Background-mode operation on both platforms so users can continue sharing while the app is minimized. • Basic safety measures—permission handling, file size limits, and graceful interruption recovery—must be in place. • Deliver clean, well-commented source code, build/run scripts, architectural documentation, and a short test video that proves two out-of-range handsets can exchange a file through a third relay device. What I’d like from you Submit a detailed project proposal outlining your suggested technology stack, multi-hop routing strategy, timeline, and milestones. Highlight prior experience with mesh networking, low-level connectivity, or offline communication apps where relevant. Acceptance criteria 1. A reproducible build for both OSs that installs from TestFlight / APK and functions without the internet. 2. Demonstration of a three-device, two-hop file transfer in under one minute for a 5 MB file. 3. Source code, documentation, and a high-level architecture diagram handed over at project close.

Hello — with 11+ years of experience building mobile networking and low-level connectivity apps, I can deliver a native, offline, multi-hop mesh sharing solution for Android and iOS that reliably relays files across intermediate devices without any internet or central server. Approach & tech stack: • Native clients (Kotlin + Android Nearby / Wi-Fi Aware / Wi-Fi Direct / BLE stack) and Swift/SwiftUI + MultipeerConnectivity on iOS for maximum reliability and background operation. • Cross-platform coordinator modules where appropriate, but low-level transport and discovery remain native for best performance and battery behaviour. • Transport: opportunistic store-and-forward with per-hop ACKs, chunked file transfer, end-to-end integrity (SHA256), and resume-on-interruption. Deliverables: • Android APK and iOS TestFlight build that demonstrate 2-hop transfer for a 5MB file. • Full source code, build scripts, CI notes, architecture diagram, and a short test video showing a 2-hop transfer. • Docs: deployment, background/permission handling, testing checklist, and tuning notes for real-world ranges. Acceptance mapping: solution runs offline, supports three-device relays, preserves file metadata, resumes transfers, and logs route decisions for traceability. I’m ready to draft a milestone plan and demo a prototype when you’re happy with the technical direction. Thanks.

Hey There!!! ⚜⭐⭐⭐⭐⚜(( Fully offline multi hop mesh networking across Android and iOS ))⚜⭐⭐⭐⭐⚜ Your vision of creating a true peer to peer mesh that keeps file transfers alive even when devices move or fall out of range is genuinely exciting. You are aiming for an app that operates without the internet, auto discovers nearby phones, and relays files seamlessly through multiple hops. I have worked with low level connectivity tools like Wi Fi Direct, Bluetooth LE, and Multipeer Connectivity, which helps in designing stable routing logic and background friendly transfers. My approach would combine adaptive multi hop routing with lightweight discovery protocols and a clean native or cross platform architecture. Three important features • Automatic multi device discovery and hop based routing • Metadata preserved file transfers running in background mode • Recovery from interruptions with secure permission handling Happy to discuss the routing strategy, technology stack, and milestones you expect so we can shape a robust offline mesh solution.
