I need a lightweight, real-time chat application built exclusively for Android phones. The core focus is text messaging—no voice calls or media sharing for this version—so the interface and back-end can stay streamlined and fast. Key goals • Smooth one-to-one text conversations with instant message delivery and read receipts • Simple, clean UI that feels native to modern Android versions • Push notifications for new messages when the app is in the background • Secure user authentication (email, phone, or social sign-in—whichever you recommend) • Cloud-hosted database for message storage and basic user profiles You’re free to choose the stack you know best (Firebase, AWS Amplify, Supabase, or a custom REST/WebSocket back-end) as long as the final APK runs reliably on current Android devices and the full source code is provided. Deliverables 1. Complete Android Studio project with well-commented code 2. APK ready for installation and testing 3. Brief setup README so I can build and deploy locally If you’ve shipped chat features before, please mention any relevant apps or GitHub samples. I’m ready to start as soon as the scope and timeline are clear.
