build a Buy-Now-Pay-Later program and need an Android-only locking solution that automatically enforces our repayment terms. Whenever a user misses a scheduled instalment the app must immediately: • trigger a full device lock that prevents normal use until the outstanding balance is cleared; • display a clear, non-dismissible reminder screen guiding the customer to our payment portal. The lock should revert as soon as my server confirms settlement. A lightweight admin console or secure API endpoint is required so my team can push payment-status updates, unlock commands, and view basic device telemetry. Code must be resilient against rooting or factory-reset attempts and comply with Google Play policies for Device Admin / Device Owner apps. Deliverables 1. Android Studio project (Java or Kotlin) with annotated source code. 2. Backend hook documentation (REST or webhook) that shows how we pass payment events. 3. Build and installation instructions plus a short video demo proving the lock and unlock flow. 4. One-month bug-fix support after hand-over.

I understand you need an Android-only BNPL device-locking solution using compliant Device Admin/Device Owner controls, repayment-status enforcement, a non-dismissible payment reminder screen, server-confirmed unlock, admin/API controls, telemetry, and clear handover documentation. I have experience building Kotlin/Java Android apps, secure backend APIs, device-management workflows, payment-status integrations, and policy-aware mobile solutions where reliability, consent, and controlled access are critical. I will implement the lock/unlock flow, REST/webhook payment hooks, secure admin endpoint, device telemetry, annotated Android Studio source, build instructions, demo video, and one-month bug-fix support with a strong focus on Google Play compliance and recoverable customer support paths. Q1: Will the devices be enrolled as company-managed Device Owner devices before delivery to customers? Q2: Which payment system or portal should the unlock confirmation integrate with? Q3: Do you need a full admin dashboard or is a secure API endpoint enough for the first version? Best regards.

What you’re really asking for is reliable enforcement, not just a lock screen, because users will inevitably try to bypass restrictions once payments are overdue. I’d approach this as a Device Owner solution rather than a standard Device Admin app. The Android client would stay connected to your backend, receive payment-status updates, and immediately switch into a restricted mode when an instalment becomes delinquent. The reminder screen would be persistent, non-dismissible, and only expose the payment flow until your server confirms settlement and sends the unlock event. On the backend side, I’d keep the API simple: payment status changes, unlock commands, and basic telemetry reporting. I’d also build safeguards around offline scenarios, delayed syncs, and tampering attempts so the device state remains consistent. I worked on a similar enforcement-focused Android project where device policies and backend-driven state changes had to remain reliable even under poor connectivity conditions. One thing I’d want to confirm first: are these devices provisioned by your company before being handed to customers, or are they customer-owned Android devices?

Hi, You need more than a lock screen , you need a controlled repayment enforcement flow that stays reliable under Android policy and device-tampering pressure. I’ve built secure Android and API-driven systems before, and I can structure this as a Device Owner/Device Admin solution with a hardened lock workflow, server-driven unlock events, and a lightweight admin endpoint for payment status and telemetry. I’ll keep the code annotated, the integration path clear, and the delivery aligned with Play policy constraints so the system is practical to deploy. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. If you’d like, I can start by mapping the lock state machine, backend event flow, and root/factory-reset handling approach in the first milestone. Which Android management mode will you require for deployment: Device Owner, Device Admin, or a dedicated MDM enrollment flow? Looking forward to your reply so we can finalize the exact plan. Best regards, Asad

Hi there, I have read your project requirement. You need an Android-based device management solution for your BNPL platform that can enforce repayment conditions, display payment reminders, communicate with your backend in real time, and provide administrative controls for lock/unlock management, status updates, and device monitoring. We have experience with Android development, Kotlin/Java, backend APIs, device management workflows, secure authentication, and enterprise mobility solutions. We can review the technical and compliance requirements, design a secure architecture, integrate backend payment-status APIs, implement administrative controls, and provide complete documentation and post-deployment support. A few questions: ============== Will the application be deployed on company-controlled devices (Device Owner mode) or on users' personal Android devices? Do you already have the BNPL backend and payment-status APIs available, or should API development be included? Which Android versions and device manufacturers must be supported? Do you require Google Play distribution, enterprise/private distribution, or direct APK deployment? Best Regards, Srashtasoft Team
