I’m building an Android utility app whose entire purpose is to boost everyday productivity. The centerpiece is a custom SDK-level tool that other apps (and future modules) can hook into, so code quality, clear architecture, and clean API design matter as much as the UI. Here’s what I need from you: • Design and develop the full Android application in Java using Android Studio and the latest Jetpack libraries. • Create the core SDK component, document its public methods clearly, and supply a small demo module that shows how third-party code would call it. • Implement a lean, modern interface that highlights the SDK’s productivity features without unnecessary bloat. • Provide unit tests and an APK for functional review; source code must be version-controlled on GitHub (or GitLab) with meaningful commit messages. I’ll supply wireframes, branding assets, and a more detailed API outline after kickoff. Final acceptance is based on clean compilation, passing tests, and smooth operation on Android 11 – 14. Let’s make a tool that genuinely saves users time.
