Apk for office television

Budget: 500 USD Deadline: 14 days

Kirill, the task is clear: you want to create a centralized content management system for clinics, so that each screen autonomously plays uploaded videos according to a set schedule without putting a load on the network. I will propose a solution with a background service for synchronizing playlists and local caching of files, which will ensure uninterrupted operation even during temporary internet outages. I have a question: do you plan to manage the playlists through a web panel, or is a simple update of the config file on the server that the devices will access sufficient?

A digital signage system is needed for the clinic: an APK on each TV pulls video from the server, caches it locally, and plays the assigned playlist without relying on the stream.

I will do it this way: an Android application in Kotlin with ExoPlayer for playback, a background WorkManager for downloading/updating video files on a schedule. Each device registers with a unique ID and receives the assigned playlist via REST API. A web control panel (Node.js + React) allows assigning playlists to specific TVs from a computer, uploading videos, and viewing the status of each device. When the playlist changes, the application receives a push notification (FCM) and pulls only new files without re-downloading all content.

The key point: synchronization of playback between screens is implemented through a common timestamp from the server; otherwise, the TVs will drift apart in time.

How many TVs are planned in one clinic, and is support for multiple clinics needed from one control panel?
