Task-Earning Android App Development

I’m building “A.S Task Earner”, an Android application where users complete light-weight activities—primarily simple clicks, quizzes and other mini games—to collect coins they can later withdraw to a UPI account.

Core user flow
• Multi-method sign-in via Firebase Authentication (email + password, Google, and phone)
• Home dashboard that shows a real-time task list served from Firebase Realtime Database
• Coin wallet with live balance, withdrawal request form, and withdrawal history
• Profile page plus FCM push notifications for new tasks, approvals, or general updates

Admin console
A separate web panel (any modern JS or Flutter web stack is fine) must let me:
– View, search, and manage every user
– Add, edit, or delete tasks and their coin values
– Credit or debit coins manually
– Approve or reject withdrawal requests and trigger notifications
– Broadcast custom messages or app-wide announcements
– Update textual or graphical content in the app without forcing a Play Store update

Tech essentials
Firebase Authentication, Realtime Database, and Cloud Messaging should anchor the backend. The app should follow best practices for secure read/write rules and token handling. Aim for a clean, responsive UI built around a green, blue and white palette, and keep transitions fluid at 60 fps on mid-range devices.

Deliverables
1. Production-ready Android APK (minSdk 23) with source code
2. Fully functional, hosted admin panel and its source
3. Firebase project setup with rules and documented collections / paths
4. Basic README for local build and future feature additions

I’d like to see short demos or repo links to similar reward or wallet-based apps you’ve completed. Let me know your timeline and any questions you need clarified so we can get started right away.
