I want to build a full-featured social networking application exclusively for Android. The core of the project is the complete design and development of an app that lets users create an account, build a profile, connect with others, and interact through a real-time feed. A clean Material Design interface, smooth navigation, and reliable back-end integration are critical. Please work in Android Studio with Kotlin (Java is acceptable if strongly preferred) and structure the code for easy future maintenance. Deliverables • Production-ready APK • Complete, well-documented source code • Brief setup guide covering environment, build steps, and API endpoints The job is considered done when the APK installs without errors on current Android versions, all listed features function as intended, and the code passes a quick review for clarity and commenting.
