Zebra Technologies, a leader in barcode printing and mobile computing, has developed a sample inventory scanning application that integrates their ruggedized handheld computers with built-in barcode scanners and the Couchbase Mobile stack. This application, demonstrated with a fictitious set of book data, utilizes Android-based devices and the Zebra DataWedge service to scan ISBN barcodes, retrieving information from a locally stored Couchbase Lite NoSQL database. The app is designed to initialize and populate inventory data through two-way replication with Couchbase Server, employing RxJava for multi-threading and using an intent-based API to handle barcode scanning. The application's architecture includes a single activity that sets up the database, starts replication, and manages scan results, with query execution based on Couchbase's N1QL query language. The project is open source and available on GitHub, offering resources for further exploration of barcode scanning integration with Couchbase and Zebra technologies.
