Centralized campaign delivery and offline-ready playback across Android advertising screens
The complete pairing-to-playback flow has been tested on a physical Android tablet. Fleet-scale capabilities remain in development.
Overview
DOOH Advertising Network connects a web administration platform with Android advertising tablets placed in retail and service locations. Operators can register screens, organize shops, upload and publish image or video campaigns, and assign content to specific devices. Each tablet downloads its assigned playlist and plays media locally, helping advertising continue even when connectivity is interrupted.
My contribution
At MT Solutions, I work on the architecture and implementation of the DOOH advertising platform, covering the Laravel backend, Filament administration, REST APIs, and Flutter-based Android kiosk player.
The end-to-end proof of concept was validated on a physical Android tablet. Additional fleet-scale capabilities belong to an ongoing implementation and are not presented here as released features.
01 — The Challenge
Managing advertising across multiple physical screens becomes difficult when every content change requires someone to visit a location. The system also has to handle device onboarding, mixed image and video formats, restarts, and unreliable connections without leaving displays idle.
02 — The Approach
I developed a Laravel API and Filament administration workflow for device pairing, shop and area records, campaign publishing, and per-device assignments. A Flutter Android player securely pairs through QR activation, downloads assigned media, and runs a looping full-screen playlist with locally cached content. The complete pairing-to-playback flow was tested on a real tablet.

03 — What it does
Activate and associate Android advertising tablets with the central administration portal using a QR-based onboarding flow.
Upload, manage, publish, and unpublish image or video campaigns from one web administration panel.
Assign campaign content to selected screens, with a shared API serving the appropriate playlist to each device.
Download media before playback and retain the last available playlist so screens can continue operating through connectivity interruptions.
A Flutter-based full-screen player that rotates images and videos, supports device restart behavior, and keeps advertising content in view.
Manage areas, shops, and registered screens with activation status and last-seen information in the admin interface.
