Katie Barnett - Let's Brew KMP: Shared Code & Shared Coffees

Описание: Let's Brew KMP: Shared Code & Shared Coffees by Katie Barnett (Android Evangelist @ Bilue | GDE Android)

Delivered at the GDG Melbourne October 2025 Meetup

Take the first steps into the exciting world of Kotlin Multiplatform (KMP) and Compose Multiplatform (CMP)! This talk is designed for multiplatform-curious developers who love a native experience but don’t want to be limited to just one platform.

I’ll show you the steps I took on the journey to build a group coffee ordering application. You’ll see how KMP allows us to write business logic once and deploy it to multiple targets, making development more efficient and consistent.

Our coffee order includes:

What you need to get set up: Kickstart your KMP development environment
KMP vs. Native Android Development: Exploring the key differences and similarities, highlighting where KMP shines and how it integrates with existing Android practices.
UI: How CMP works to build UI cross platform
Lessons Learned Along the Way: What has tripped me up in this new way of thinking!
