I want a full-featured social networking app built exclusively for Android. The core experience must allow users to create and edit profiles, exchange real-time messages, and browse an engaging content feed. Each of these three functions—profile creation, messaging, and feed consumption—has equal priority for the first release. You will handle everything needed to get a production-ready APK into Google Play: clean, well-documented Android code (Kotlin or Java), integration with a lightweight yet scalable backend of your choice, and a simple but modern UI that follows current Material Design guidelines. Authentication may start with email/password; social sign-in can follow in a later milestone. At hand-off I need: • Compilable source code with clear build instructions • A signed release APK ready for store submission • Brief documentation outlining architecture, major libraries, and how to spin up the backend for testing Please let me know your estimated timeline, any similar apps you have shipped, and the approach you’d take to keep the chat, profile management, and content feed fast and secure.
