This project centres on building a complete, production-ready Android application from the ground up. I already have the concept defined and supporting materials prepared; what remains is transforming these ideas into a polished, stable mobile experience that runs smoothly on modern Android devices. Scope of work • Design the user interface in line with current Material Design guidelines, ensuring responsive layouts across common screen sizes. • Develop the app natively in Kotlin (Java is acceptable if strongly preferred) and integrate any required APIs or third-party SDKs. • Implement secure data storage, network communication and in-app navigation consistent with best practices. • Thoroughly test the build (unit, integration and user acceptance) and address edge-cases before final hand-off. • Package the signed APK/AAB, prepare Google Play assets (screenshots, feature graphic, listing text) and guide me through the first store submission. Deliverables 1. Complete, well-commented source code in a private Git repository. 2. Release-ready APK/AAB plus debug build for internal testing. 3. Brief technical document covering architecture, API keys, build steps and any future maintenance notes. 4. Design assets (Figma/Adobe XD files or equivalent) for future reference. Acceptance criteria • App installs and operates without crashes on Android 10+. • All agreed features function exactly as demonstrated in the final test session. • Code passes a quick review against the Android Kotlin Style Guide and contains no hard-coded secrets. • Google Play Console shows the first production release approved. If you need additional details—wireframes, backend endpoints, or specific feature lists—let me know and I can share them immediately.
