I need a clean, reliable Android-only utility app built from the ground up. The core functionality centers on helping users perform a specific task even when they are offline, then quietly syncing any new data the moment a connection is available. Timely push notifications will keep them informed of status changes and reminders. Key requirements • Push notifications • Automatic data synchronization whenever connectivity returns • Full offline functionality so every main workflow operates without a signal Please design, code, test, and package the APK ready for Google Play submission (including basic icons, splash screen, and store listing assets). Source code should be well-commented and handed over on completion, along with a short setup/read-me so I can build future versions locally. I’m happy to clarify any edge cases or provide sample data formats once we agree on the general architecture and preferred SDKs or libraries.
