AndroidChallenge
Provide a single mobile solution for multiple departments, integrate with legacy SAP systems, ensure secure authentication and offline operation for field officers, and deliver an intuitive UI for users with varied technical backgrounds.
Approach
Lead the mobile development within a cross-functional team, we followed a full-cycle approach including requirements gathering and user stories, estimation, iterative delivery, and guided deployments. The app was built with Ionic/Angular atop Cordova/Capacitor, with custom Java-based Cordova plugins for barcode scanning and decryption, SQLite, content providers, native HTTP, and Bluetooth printing. We instituted validation, auto-save, session state, and geolocation, and established a support and knowledge-transfer path for long-term sustainability.
