Desarrollo APP - Multimedia

General Description:
We are Upper Digital Signage, a cloud-based solution specialized in digital signage for meeting rooms. We are looking for an experienced Android developer to create a new application that will function as a multimedia content viewer, allowing our clients to display images and videos on their screens.

The app will integrate with our existing infrastructure, which includes Firebase as the backend.

Project Objectives:
Develop an Android application that connects to our Firebase database.
Display content (images and videos) as configured through our web-based control panel.
Implement a simple authentication system (via device code or email/password).
Display content in fullscreen mode (without navigation bar).
The backend will define a template for displaying the content (images/videos), and the app must be able to read this layout and present the content accordingly.
Allow periodic content refresh (interval configurable via Firebase or local settings).
Offline functionality: retain and display the last downloaded content in case of lost internet connection.

Thank you!
