Happy Ring required an Android SDK that was built using modern development practices, specifically utilizing Kotlin and coroutines to ensure efficient and maintainable code.

There were uncertainties regarding the differences in BLE architecture between iOS and Android platforms. Happy Ring needed expertise to navigate these differences and ensure seamless communication between the ring and Android devices.

Without a defined list of target devices, the SDK needed to function smoothly across a wide range of Android devices from different manufacturers, each with its own implementation of BLE.

Ensuring a stable connection for continuous data transfer, even in adverse conditions like frequent app updates, or phone restarts, was critical.

The final SDK provided a stable connection and data transfer across multiple Android devices from different manufacturers, successfully handling various edge cases.

Happy Ring was impressed with the modern architectural approach of the Android SDK. They considered applying similar practices to their existing iOS SDK, recognizing the benefits in simplicity and reduced risk of issues.

Through this project, Intent reinforced its expertise in wearable device software development, particularly in handling BLE communications and utilizing modern Android development tools and practices.
