The core features of my Android app are already coded, but persistent bugs—especially around real-time notifications—are preventing a full launch. I need you to step in, diagnose, and resolve every remaining issue so the application reaches 100 % stability and passes Google’s review first time. Scope of work • Investigate and repair the current real-time notification failure (messages are never delivered). • Run a complete QA sweep, squashing any other crashes, UI glitches, or performance problems you uncover. • Wire up Firebase, external APIs, and the payment gateway should any of those links still be missing or mis-configured. • Prepare production-ready builds: signed APK and AAB produced with a fresh keystore. • Upload the release to my Google Play Console and walk through Developer Verification until Google accepts the submission. Deliverables 1. Fully functional source code in Android Studio format. 2. Production keystore + password and the final APK/AAB. 3. Any service credentials or console access tokens generated during the job. 4. Change log summarising every fix applied and where it lives in the codebase. Acceptance criteria – Push notifications arrive instantly on multiple test devices running Android 8 – 14. – No crashes in Play Console pre-launch report. – App approved for publishing without further changes. If you have proven experience debugging and shipping Firebase-powered Android apps, this should be straightforward work. I’ll be available for quick answers and can provide immediate access to the repository and Play Console once we start.

Your notification failure is almost certainly a Firebase Cloud Messaging token registration issue or a misconfigured server key—both will silently drop messages without throwing errors. If the backend PHP script is sending to an expired token or using legacy HTTP v1 instead of the current API, notifications will never reach devices. Quick questions - are you currently storing FCM tokens in your database and refreshing them when onNewToken fires? And is your backend sending notifications through Firebase Admin SDK or the deprecated HTTP API? Here is the architectural approach: - ANDROID STUDIO: Audit FCM token lifecycle, verify onMessageReceived handles both foreground and background states, and confirm notification channels are registered for Android 8+. - PAYMENT GATEWAY INTEGRATION: Test Stripe/Razorpay sandbox flows end-to-end, implement webhook listeners for async payment confirmations, and add retry logic for network failures. - API INTEGRATION: Validate all endpoint responses with proper error handling, implement token refresh for expired sessions, and add request timeouts to prevent ANR crashes. I've debugged and shipped 8 Firebase-powered Android apps that passed Play Console pre-launch reports on first submission. Let's schedule a 15-minute call to review your current FCM implementation before you commit to a timeline.

Hi, I can help you debug and stabilize your Android app, fix the real-time notification issue, complete a full QA review, configure Firebase/APIs/payment gateway if needed, and prepare a production-ready APK/AAB for Google Play submission. Notification issues are often caused by Firebase Cloud Messaging (FCM) configuration, notification permissions (Android 13+), background services, token handling, server-side delivery, or API integration issues. I'll identify the root cause and apply a permanent fix rather than a temporary workaround. I've worked on similar Firebase-powered Android applications involving push notifications, Play Store deployments, payment integrations, and production bug fixing. One question: Are the notifications triggered directly from Firebase Cloud Messaging, or through your own backend server? I'm available to start immediately. Share the repository and Play Console access, and I'll review everything and get started right away.

With extensive experience in Mobile App Development, specifically Android app services, I understand your frustration with the bugs plaguing your app's core features. My expertise in Firebase and Android Studio makes me the perfect candidate to diagnose and resolve these issues, ensuring your app attains full functionality and passes Google's review process. I pride myself on my thorough approach to projects, which involves not only fixing apparent issues but also conducting an entire QA sweep to detect any unnoticed crashes, UI glitches, or performance problems that might compromise the final product. In this context, I'll ensure that real-time notifications are fixed, messages are delivered promptly on multiple devices running Android 8 – 14 with no pre-launch console crashes. Upon delivery, you'll receive comprehensive documentation of every fix applied and their exact location in the codebase. Given my background in Full-Stack development not only in Android (Java), but also MERN/MEAN and other languages/frameworks such as PHP (Laravel), Python (Django) or Vue.js among others, I am confident in my ability to handle this project proactively.

Let’s get started on delivering a robust, efficient and reliable service.

Since your Android app is already feature-complete, I’d avoid unnecessary rewrites and start by tracing the notification path end to end: device registration, FCM token lifecycle, backend payloads, Android notification channels, background restrictions, and delivery behavior across Android 8-14. My two priorities would be clean implementation and stability. I’d fix the root cause of missed notifications, then run a structured QA pass covering crashes, lifecycle issues, UI problems, API/Firebase configuration, payment integration, permissions, and Play Console pre-launch findings. This should reduce launch risk instead of patching individual symptoms. I can take ownership through release preparation as well: signed APK/AAB, fresh keystore, configuration checks, changelog, Play Console upload, and Developer Verification guidance. I’ll target first-pass submission readiness, while keeping Google’s final approval as an external review decision. A relevant project is FileChannels, where we worked on a mobile application with PubNub real-time messaging, Agora calling, file sharing, CRM sync, and other live communication workflows.
