Hi there, I have read your project requirement. You need an Android Device Owner (DPC) application for an EMI locker platform with remote lock/unlock, QR provisioning, FCM control, anti-tamper protection, and strong compatibility across OEM devices. We have solid experience working with DevicePolicyManager, Device Owner provisioning, and enterprise Android (DPC apps), and can build a secure, production-ready solution using Kotlin. The app will support QR-based provisioning (factory reset flow), lock task mode, custom lock screen with EMI details, FCM-triggered lock/unlock, and a resilient background service with heartbeat reporting. We will also implement anti-tamper checks (root, bootloader, Play Integrity API) and ensure stability across major OEMs. We are familiar with TestDPC and can use it as a base reference while building a clean, maintainable production architecture tailored to your backend APIs. A few questions to align the implementation: ===================================== Is your backend (APIs for lock/unlock, payments, heartbeat) already ready? Do you require offline fallback behavior if the device loses connectivity? What level of customization is needed for the lock screen UI/branding? Any specific OEMs/devices you want prioritized for testing first? Best Regards, Srashtasoft Team

I have read your job post and I can help you build the Android EMI locker app. I am an Android developer with experience in Kotlin, device admin apps, Firebase, and REST API integration. I have worked on system-level Android features and background services. I understand you need a Device Owner (DPC) based app, and I am familiar with DevicePolicyManager, FCM messaging, and QR provisioning flows. I have also worked with secure apps that include lock/unlock logic, device checks, and backend communication. My approach is to start with the Device Owner setup using a clean DPC structure (similar to TestDPC), then build QR-based provisioning, lock screen UI, and backend sync through FCM. I will also add anti-tamper checks, heartbeat service, and multi-language support as required. You will get a stable Android app that works across major OEMs, integrates with your backend, and is ready for real-world EMI use cases.

Hey, Device Owner apps with DevicePolicyManager — niche work, I’ve been in this space. What I’ve handled: • DevicePolicyManager + DeviceAdminReceiver implementation • Lock task mode + custom lock screen overlays • FCM-triggered remote lock/unlock • Background services surviving OEM battery optimization (Xiaomi, Samsung, Realme — all the aggressive ones) • Play Integrity API + root detection + bootloader checks Your stack mapped out: • QR provisioning → Android DPC provisioning flow via NFC/QR on factory-fresh devices • FCM → lock/unlock commands from your backend • Heartbeat service → WorkManager with OEM battery whitelist handling • Custom lock screen → EMI info display, payment CTA • Multi-language → Hindi, English, regional via Android locale system Familiar with TestDPC reference implementation — good baseline for provisioning flow. OEM compatibility across Samsung/Xiaomi/Realme/Vivo/Oppo is tricky but manageable with targeted workarounds per manufacturer. What’s your backend stack for the lock/unlock command API? — Arun

@ModernTechno442

Being a seasoned Android developer with over 7 years of experience, I understand the significance of building robust, customer-friendly apps end-to-end. My extensive expertise aligns impeccably with your requirements for an Android developer to design an EMI locker app similar to 101Locker and InstenLock. I have in-depth experience working with Android Device Policy Manager (DevicePolicyManager) APIs, constructing Device Owner(Android's DPC) applications and implementing QR code-based provisioning during initial device setup. Moreover, my familiarity with Firebase Cloud Messaging (FCM) will be invaluable in integrating features that allow remote locking and unlocking based on EMI payments. Similarly, my proficiency in Kotlin, REST API integration and Android Enterprise/Android for Work will help ensure compatibility with major Android OEMs like Samsung, Xiaomi, Realme, Vivo and Oppo for a seamless mobile experience.

@nathanholmes

The Device Owner and provisioning requirements are the most critical part of this build because EMI locker apps depend heavily on reliable policy enforcement across different Android OEMs. Features like remote locking are relatively straightforward in controlled environments, but handling battery optimization, tamper detection, provisioning flow, and manufacturer-specific behavior is where these systems usually become difficult. I’d approach this by building the app around a stable DPC architecture with QR-based provisioning, resilient background services, and carefully structured policy management using DevicePolicyManager APIs. Compatibility testing across Xiaomi, Vivo, Oppo, Samsung, and Realme devices would also need to be treated as a core development phase rather than an afterthought. I’ve worked on Android systems involving device management, background services, FCM-driven workflows, and policy-controlled app behavior where stability and edge-case handling were critical. I’m also familiar with the TestDPC reference approach and how it can be adapted into a production-oriented locker workflow. Happy to discuss how I’d structure the provisioning and lock/unlock pipeline if useful.
