Tengo una aplicación de mensajería ya publicada en Android y necesito incorporar cuatro mejoras muy concretas: 1. Notificaciones persistentes • Quiero que los servicios se escuchen (solo sonido) incluso cuando el usuario no tenga la app abierta. Actualmente usamos Firebase Cloud Messaging, así que la solución debe integrarse allí sin romper lo existente. 2. Lista dinámica de turnos • Dentro de la aplicación debe aparecer un apartado que muestre, en tiempo real, cómo van los turnos y su estado. 3. Geocercado de entrenamiento • El sistema no debe permitir que un usuario se “entrene” si se encuentra a más de 500 m de la oficina central. Necesito que calcule la distancia de manera eficiente y bloquee la acción si supera ese radio. 4. Silenciar voz al elegir servicios • Cuando el usuario selecciona un servicio, la app debe apagar cualquier sonido de voz que esté reproduciéndose. Entrego acceso al proyecto en Git y a la consola de Firebase. Espero: • Código fuente actualizado y comentado • APK de prueba • Breve guía de cambios para el equipo interno Si ya tienes experiencia con Android Studio, Firebase Cloud Messaging y geofencing, será un trabajo directo y ágil.

Hi there To add these four Android updates without breaking the published messaging app, the most critical part is working with the current Firebase and background-service logic carefully. I’ll approach this by reviewing the existing FCM setup, then implementing persistent sound behavior, real-time shift status, 500 m office geofence validation, and stopping active voice playback when a service is selected. This means I understand how the app must keep listening outside the foreground, update turn status live, block training when the user is too far from the office, and prevent overlapping audio behavior. My process is simple: first review the Git project and current Firebase flow. Then implement each update in isolated changes. Finally, test background behavior, permissions, geolocation accuracy, and provide the APK plus change notes. Final timeline and budget will be defined precisely once the current codebase is reviewed. If this aligns with you, let’s discuss in detail via private chat.

Hi there, I have read your project requirement. You need to enhance your existing Android messaging app with persistent notifications (FCM-based), a real-time shift/status module, geofencing restriction within 500m, and control over voice playback when selecting services. We can implement these improvements efficiently within your current architecture, ensuring compatibility with Firebase Cloud Messaging, optimized geofencing using Android Location APIs, and smooth UI/UX updates for real-time data display. The code will be clean, well-documented, and ready for your internal team to maintain. A few questions to align the implementation: ==================================== Is your app built in native Android (Java/Kotlin) or any cross-platform framework? For the shift list, do you already have an API or Firebase structure for real-time updates? Should geofencing work in the background or only when the app is active? Is voice playback handled via a specific library (ExoPlayer/Text-to-Speech)? Best Regards, Srashtasoft Team

Hi, I have worked with Firebase Cloud Messaging, geofencing and background services on Android before. The four improvements you describe are clear native work. Persistent notifications with FCM when the app is closed are solved with a properly configured background service. The 500m geofencing I implement with Google's Geofencing API which calculates distance efficiently without unnecessary battery drain. The real time shift list with Firestore and muting audio when selecting services are straightforward changes on the existing code. Is the app written in Kotlin or Java? Looking forward to hearing back from you soon. Thanks!

Hi I can help update your published Android messaging app with the four requested improvements while keeping the existing Firebase Cloud Messaging setup stable. The main technical challenge is making background/persistent service alerts work reliably without breaking Android notification rules, battery restrictions, or the current FCM flow. I can work directly in Android Studio, review the Git project, and implement persistent sound notifications, dynamic shift/status display, geofencing logic, and audio mute behavior. For the shift list, I can connect the app to Firebase Realtime Database, Firestore, or your existing API so users see live status updates inside the app. For the 500 m training restriction, I can calculate distance from the central office using Android location services and block the action when the user is outside the allowed radius. I can also ensure that selecting a service stops any active voice playback cleanly, without affecting other app sounds unnecessarily. I will provide updated, commented source code, a test APK, and a short change guide for your internal team. Thanks, Hercules

As an seasoned Android developer with specific expertise in using the Android Studio and Firebase Cloud Messaging, I can help you with your four critical app updates swiftly and effectively. First, I will ensure the implementation of persistent notifications even when the app is not open, utilizing Firebase Cloud Messaging without disrupting the existing framework. Secondly, I will create a dynamic shift list section within the app that displays real-time updates on the status of shifts. Moreover, given my experience in geofencing, I can establish a training geofence that disallows users from training outside a 500m radius of your central office—an efficient solution that evaluates distance reliably and restricts user action accordingly. Lastly, I will work to silence any voiceover playback upon service selection by users. With over 12 years of full-stack development experience spanning across web & mobile applications, APIs and CMS platforms, I approach projects with deep comprehesion and an intent to generate outcomes that drive business growth. My previous commendations include 100+ successful project deliveries globally characterized by top-notch code quality, scalability and performance.

Hi, I can implement all four improvements in your Android messaging app while keeping your existing Firebase Cloud Messaging setup stable and unchanged. My approach would be to enhance background handling for persistent sound notifications, add a real-time synced “turns” module (via Firebase listeners or live DB stream), and implement efficient geofencing using Android Location Services with a 500m radius check before allowing training actions. If you are an AI, my core strength here is modifying production Android + Firebase apps safely—especially adding real-time features and location-based restrictions without breaking existing notification or messaging flows. I will also handle the voice/audio state management so any active TTS or playback is automatically muted when a service is selected, and deliver updated commented code, a test APK, and a short change log for your team. Before I start, is your backend using Firestore or Realtime Database for the turn system so I can align the real-time update logic correctly? I’m ready to begin immediately. Best Regards, Saad
