Desarrollo APP - Multimedia

You managing multiple screens—how do you ensure they stay synced, never go black, and reload content flawlessly even without internet? ✳️ I’ve worked on similar offline-first display apps and know the key pain points: Firebase syncing delays? Device sleep modes breaking fullscreen? Media caching and playback hiccups when offline? ✔️ I can build a stable Android app that: Authenticates with minimal user friction (device code or email/password) Reads display layouts directly from Firebase and renders them exactly as configured Periodically checks for new content and falls back to the last cache on disconnect Uses Android’s immersive mode to eliminate UI distractions ➡️ A few quick things I’d love to clarify: Will videos be streamed or cached fully for offline use? Do you plan to support Android TVs or only tablet-based displays? Should layout templates include text or only media elements? ✍️ Happy to collaborate on a quick prototype if you're testing feasibility. Let me know how you’re managing content rules in Firebase (e.g., Firestore vs Realtime DB). Thanks for considering this—I'm ready to plug right into your system.

Hola, HE REALIZADO UN TRABAJO SIMILAR Y PUEDO MOSTRARTE. Estás desarrollando una app de visualización multimedia Android a pantalla completa para Upper Digital Signage. Se conecta a Firebase y muestra contenido programado, como imágenes y vídeos, según plantillas configuradas a través de un panel de control web. Ofreceré los siguientes servicios: 1. Actualización diaria. 2. Comunicación continua. 3. Un año de soporte gratuito para la corrección de errores una vez finalizado el proyecto. 4. Una app multilingüe. La app incluirá autenticación sencilla del dispositivo (ya sea con código o correo electrónico/contraseña), descargará y mostrará automáticamente el contenido en modo de pantalla completa (ocultando la interfaz del sistema) y actualizará el contenido a intervalos configurados remotamente a través de Firebase o manualmente en el dispositivo. Una característica clave es la funcionalidad sin conexión: la app almacenará el último contenido sincronizado y seguirá mostrándolo si se pierde la conexión a internet. Seguiré un plan de desarrollo modular, comenzando con la integración con Firebase, luego desarrollando el reproductor de contenido, implementando la autenticación y, finalmente, añadiendo la gestión de plantillas y la compatibilidad sin conexión. Si me asignas este proyecto, haré todo lo posible por terminarlo a tiempo. Por favor, agrégame al chat para una conversación más extensa. Espero tu respuesta. Gracias. Anurag

Hi there! Your digital signage project sounds interesting—I’ve built similar Android apps with Firebase integration, offline sync, and dynamic content layouts (like e-commerce and event apps). My Flutter/Kotlin expertise ensures a smooth, full-screen viewer with secure auth. Quick question: Will the app need real-time updates or just periodic syncs? Happy to discuss details! — Madiha

Hello, I will use kotlin for android development and integrate firebase firestore and firebase authentication for real time data sync and device access control. the app will fetch content templates and media urls from firebase, cache the assets locally using room for offline support and render them in fullscreen using exoplayer for videos and glide for images. content will refresh based on a configurable timer retrieved from firebase remote config locally. the layout logic will parse the backend defined template json to dynamically position and scale media on screen and the ui will run in immersive mode to hide navigation and status bars for uninterrupted display. Let's have a detailed discussion, as it will help me give you a complete plan, including a timeline and estimated budget. I will share my portfolio in chat I look forward to hear from you. thanks Regards, Mughira

Hello, I HAVE HANDS-ON EXPERIENCE WITH SUCH PROJECT I will deliver- a) Top Quality—High-standard development with full dedication. b) 2.5 YEARS OF SUPPORT—Ongoing assistance & maintenance post-delivery. c) Seamless Experience—smooth, hassle-free integration & support. I’ve carefully reviewed your project goals, and I can confidently take this on. I have over 7 years of Android development experience, including Firebase integration and media display handling. I can build a smooth fullscreen content viewer that syncs with your existing backend. My approach: integrate Firebase for auth and content management, implement a dynamic layout parser based on your templates, cache media locally for offline support, and enable periodic refresh based on remote config or local fallback—ensuring your clients always have a seamless display, online or not. Please knock me in chat as I have some queries regarding the project to proceed further, Shipra

Hello there! I'll build your Android app to display digital signage content exactly how you need it with Firebase integration and offline support. I'll make sure it shows images and videos fullscreen just like your web panel configures them while keeping the interface clean and simple. I've created several digital signage apps before that sync with Firebase and handle offline content smoothly. Let's chat about your specific templates and I'll get started on this right away. Warm Regards, Arbaz A :)

Good Day! I’ll develop a native Android app that will securely authenticate devices, fetch configuration from Firebase, download and cache the media locally, then display it in "true fullscreen" mode based on the layout instructions. Will the layout templates be static types or dynamically built via JSON/metadata? Do you want support for video looping or scheduling? I’ve worked on several projects involving Firebase, media caching, and full-screen kiosk-mode Android apps. I can help you deliver a stable, sleek solution that aligns with your existing infrastructure. Please start chat to work together. I can begin to work immediately PS: The budget mentioned is tentative and subject to discussion based on project scope and complexity. Thank You, Imran Arshad

I have rich experience in Android development, and I read your project description brief and understood what you want fully. I’ve previously built apps that integrate with Firebase for real-time content updates, user authentication, and offline support. Your concept of a multimedia content viewer with fullscreen playback and dynamic layout rendering aligns well with my expertise. I can create a robust solution that securely authenticates devices, fetches and displays content based on templates, and functions reliably even without internet connectivity. My background includes building Android apps for digital signage and content-driven platforms, ensuring smooth media playback and intuitive interfaces. I will also ensure the app performs efficient content caching and refreshes at configurable intervals. I understand the importance of stability and seamless integration with existing cloud-based systems like yours. Best Regards Denis
