We are looking for an Android developer to build a background service application for Android 11 devices. This project is Android-side implementation only. All backend APIs will be provided, and the work mainly involves integrating the Android app with our existing APIs. The app will run continuously in the background as a foreground service (with a persistent notification) and will not have any user interface. App Distribution and Updates: This app will NOT be distributed via the Google Play Store. Play Store-specific policies do not apply. The app must implement its own secure OTA update mechanism using our backend APIs. Project Scope: * Foreground background service compliant with Android 11 limits * Integration with provided REST APIs (HTTPS) and MQTT endpoints * Secure device onboarding using API-provided credentials * Periodic heartbeat and telemetry reporting Functional Requirements: * Configurable sending telemetry to API interval * Collect device information such as network status (SIM, signal strength, data usage, WiFi) * Collect device health information (CPU, RAM, storage, battery) * Optional GPS reporting (policy controlled, can be disabled) * WiFi hotspot (SoftAP) control and monitoring * Mobile network monitoring (signal strength, operator info) Security: * All communication over encrypted channels (HTTPS, MQTT) OTA Update Requirements: * Custom OTA update flow for the app * Checksum and signature verification * Download resume support * Status reporting to backend * Automatic rollback on failure Deliverables: * Android Studio project with clean, modular code * Background service with network and MQTT integration * Configuration handling via APIs * Basic unit or integration tests * Build and setup documentation Notes: * Backend APIs, endpoints, and formats will be provided * Focus is on Android integration and reliability * Some features may require system or privileged permissions (to be discussed) * Clean and maintainable code is expected Ideal Candidate: * Experience with Android 11 background and foreground services * Comfortable with API integration * MQTT experience is a plus * Experience with non–Play Store deployments is helpful

Hello There!!! ⚜⭐⭐⭐⭐⚜(( Android 11 foreground service with secure API, MQTT, and custom OTA ))⚜⭐⭐⭐⭐⚜ Running a continuous background service on Android 11 without a user interface is where many apps fail, especially with system limits, network reliability, and update safety. Your requirement for a persistent foreground service, non Play Store distribution, and a robust OTA flow clearly shows this is a production grade system, not a demo app. The core goal here is a stable Android service that stays alive, communicates securely with your backend, reports device and network health, and updates itself safely over the air. I have hands on experience with Android foreground services, REST and MQTT integration, and device level monitoring where reliability matters more than visuals. My approach would focus on a modular service architecture, strict lifecycle handling, and a fail safe OTA pipeline with verification and rollback to protect deployed devices. Key features I would prioritize: * Android 11 compliant foreground service with strong lifecycle control * Secure API and MQTT integration with configurable telemetry intervals * Reliable custom OTA updates with verification, resume, and rollback If this aligns with your expectations, I would be glad to discuss permissions, edge cases, and rollout strategy in more detail. Warm Regards, Farhin B.

Hello, I’m an experienced Android developer with a strong focus on background and foreground services, device-level monitoring, and reliable API integrations on Android 11+. I’ve built service-only Android applications that run continuously with persistent notifications, handle strict background execution limits, and operate without any UI or Play Store dependencies. For this project, I can implement a robust foreground service that integrates cleanly with your REST APIs and MQTT endpoints, handles secure device onboarding, and reports telemetry and heartbeats at configurable intervals. I’m comfortable working with system-level APIs to collect network status, device health metrics, optional GPS data, and to manage and monitor WiFi hotspot and mobile network information, subject to permission constraints. I also have experience designing custom OTA update mechanisms outside the Play Store, including secure downloads, checksum/signature verification, resume support, status reporting, and safe rollback handling to ensure device stability. I prioritize clean, modular code, reliability, and clear documentation to make long-term maintenance straightforward. I’m happy to discuss any privileged permission requirements early to ensure feasibility and compliance. Looking forward to collaborating and delivering a stable, production-ready Android service. Regards, Ekta

I specialize in robust, battery-efficient Android background services, having recently deployed a network monitoring solution compliant with Android 11/12 mandates. Building a reliable service for persistent WiFi and network handling integrated via a custom API is directly within my core expertise. We need to ensure minimal OS throttling for this critical background task. I will utilize Kotlin and implement the service using `WorkManager` for guaranteed execution persistence, leveraging `Foreground Service` requirements only where absolutely continuous monitoring is required. Network state changes will be managed via `ConnectivityManager` callbacks to minimize resource drain. API integration will be handled efficiently using Retrofit and structured concurrency (Kotlin Coroutines) for reliable, non-blocking data exchange, ensuring clean separation of business logic from the UI thread. All network operations will adhere strictly to Android 11’s runtime permissions structure. Is the backend API RESTful or gRPC, and what is the maximum latency tolerance for network failures that the service must handle? I am ready to review the API specs immediately. Let's start a quick chat to align on the required service reliability and Android 11 behavior compliance, ensuring we architect a truly invisible and reliable solution.
