Netflix is a subscription-based streaming service that allows our members to watch TV shows and movies without commercials on an internet-connected device. You can also download TV shows and movies to your iOS, Android, or Windows 10 device and watch without an internet connection.

Experience Management

As noted earlier, our user needs vary significantly from one production to the next. This translates to a large number of app configurations to toggle feature availability and optimize the in-app experience for each production. Decoupling the code that manages these configurations from the apps themselves helps to reduce complexity as the apps grow. Our first exploration with code sharing involves the implementation of a mobile SDK for our internal experience management tool, Hendrix.

At its core, Hendrix is a simple interpreted language that expresses how configuration values should be computed. These expressions are evaluated in the current app session context, and can access data such as A/B test assignments, locality, device attributes, etc. For our use-case, we’re configuring the availability of production, version, and region specific app feature sets.

Poor network connectivity coupled with frequently changing configuration values in response to user activity means that on-device rule evaluation is preferable to server-side evaluation.

This led us to build a lightweight Hendrix mobile SDK — a great candidate for Kotlin Multiplatform as it requires significant business logic and is entirely platform agnostic.

Implementation

For brevity, we’ll skip over the Hendrix specific details and touch on some of the differences involved in using Kotlin Multiplatform in place of Kotlin/Swift.

Build

For Android, it’s business as usual. The Hendrix Multiplatform SDK is imported via gradle as an Android library project dependency in the same fashion as any other dependency. On the iOS side, the native binary is included in the Xcode project as a universal framework.

Developer ergonomics

Kotlin Multiplatform source code can be edited, recompiled, and can have a debugger attached with breakpoints in Android Studio and Xcode (including lldb support). Android Studio works out of the box, Xcode support is achieved via TouchLabs’ xcode-kotlin plugin.
