I’m starting small and need a straightforward Android application that focuses on one core feature: secure user login. The scope is deliberately simple so we can move fast—no in-app payments or push notifications at this stage, just a clean, reliable sign-in flow. What I expect from you: • A production-ready Android app (Kotlin or Java) that lets users register, log in, and log out. • Basic UI that’s intuitive and easy to brand later. • Secure handling of credentials, preferably with Firebase Auth or another trusted backend you recommend. • Full source code and a brief README so I can build and test locally. Once the login module runs smoothly, there’s room to expand the project, but for now the milestone is a functional APK demonstrating solid authentication.
