## Overview

This appears to be a small Android app with activity screens and task- and user-related classes. The tree suggests registration and task-list capabilities, but no README or application source was provided, so screen transitions, data flow, persistence, and activity-to-layout wiring cannot be established. The graph therefore shows the identifiable runtime components without inferring connections.
