My Android app is already live on Google Play and backed by Firebase; the only thing missing is a hands-off way to keep product prices current. I want the app to pull the latest figures automatically from an external API instead of entering them by hand. Here’s what I need from you: • Identify a suitable public or third-party pricing API, advise me on the sign-up process, and secure the required key and docs. • Plug that API into the existing Kotlin/Java codebase, map the returned values to my current Firebase structure, and schedule background fetches so prices stay fresh without draining the battery. • Test the end-to-end flow (API → Firebase → UI) and show me the result in a quick build so I can verify accuracy. • Prepare a concise note explaining any new classes, dependencies, or Cloud Functions you add for future maintenance. The code is well-organised and version-controlled on Git, so you’ll have what you need to jump straight in. I’m aiming for a fast turnaround and a fair, sensible fee—no endless scope creep, just one clear enhancement delivered cleanly.

Syncing Android app prices requires a reliable backend to handle data communication and ensure that the app reflects current changes accurately. Since you need this handled efficiently, I can step in to manage the PHP-based API or database logic required to keep your pricing information updated across your Android environment. While my primary focus is web development, my 15 years of experience in PHP, JavaScript, and server-side management give me the technical background to build or fix the sync processes that bridge your data and the mobile interface. I regularly handle backend architecture and system integrations, so I can ensure your price synchronization is stable and performs without lag. I can complete this task for $16.39 within 1 day. Let me know the details of your existing setup so I can start working on the synchronization fix immediately.

Keeping your product prices in sync automatically is a clean, well-scoped enhancement, and I've built exactly this kind of pipeline before with Kotlin, Firebase, and third-party pricing APIs. My approach: I'll evaluate and integrate a suitable pricing API (like Open Price or a domain-specific provider), map its response schema directly to your existing Firebase Realtime Database or Firestore structure, and schedule background fetches using WorkManager to keep things battery-efficient. I'll wire up a Cloud Function if server-side sync makes more sense for your use case. You'll get a testable build showing the full API → Firebase → UI flow, plus a short maintenance doc covering every new dependency and class. I can start right away—my calendar is open and this is the kind of focused work I enjoy most.

Hey there! Price sync features usually fail when APIs aren’t reliable, background jobs drain battery, or data mapping breaks between API and Firebase. I’d solve this by integrating a stable API with efficient background syncing and clean data mapping. I’ve spent over 10 years working on mobile apps and API integrations, so adding real-time data updates into an existing Android + Firebase setup is something I can do quickly and cleanly. I’d first identify a reliable pricing API (based on your product type), handle the key setup, then integrate it into your Kotlin codebase with proper mapping to your Firebase structure. For updates, I’d use WorkManager for scheduled background sync (battery-efficient and reliable), ensuring prices stay fresh without impacting performance. If needed, I can also add a lightweight Cloud Function for centralized updates. I’ll test the full flow (API → Firebase → UI), deliver a working build, and provide a clear note explaining everything added so you can maintain it easily. I keep things simple, clean, and production-ready — no overengineering.

Hi, Right now, your app depends on manual price updates, which quietly creates a bigger problem over time—users start seeing outdated data even though your Firebase backend and Play Store app are already solid. I understand your Android app is live, built in Kotlin/Java, and structured around Firebase, and what you need now is a clean, automated pricing layer that removes manual work completely. I’ll identify a reliable external pricing API, guide you through access/setup if needed, and integrate it directly into your existing codebase using Retrofit/OkHttp. The data will be mapped cleanly into your current Firebase structure, so nothing breaks or needs redesign. To keep everything efficient, I’ll implement scheduled background syncing using WorkManager, ensuring updates run in the background without draining battery or slowing the app. Then I’ll test the full pipeline end-to-end (API → Firebase → UI) and give you a quick build for verification. You’ll also get clean Git documentation explaining every new class and dependency added. I can start immediately and keep this lean, stable, and production-safe. Do you already have a pricing API in mind, or should I shortlist the most reliable options for your use case?
