The Problem

The client needed to support multiple RFID Android devices from various manufacturers within their application. Each manufacturer provided a different SDK with unique methods and handling processes, leading to challenges in ensuring seamless integration and consistent functionality across devices.

Proposed Solution

To address this challenge, we designed a common interface that standardized interactions with all supported RFID devices. This interface acted as a unified layer, abstracting the differences between the various manufacturers' SDKs. By implementing Kotlin Flows, we enabled reactive listening for device changes, allowing the application to respond dynamically to events from any connected RFID device.

Key Implementation Details

• Common Interface Development:: We created a common interface that provided a consistent set of methods and properties for all RFID devices, regardless of the manufacturer. This approach simplified the integration process and allowed the client to interact with different devices uniformly.
• Kotlin Flows for Reactive Programming: By utilizing Kotlin Flows, we enabled the application to listen for device changes in real-time. This reactive programming model allowed the client app to automatically respond to events such as device connections, disconnections, and data changes, ensuring that the business logic remained responsive and up-to-date.
• Integration with Business Logic: The common interface seamlessly integrated with the client’s existing business logic, allowing the application to function smoothly across all supported RFID devices. This ensured that the client could maintain consistent operations and user experiences, regardless of the device in use.
