Dynamic theming on the Pixel is an amazing feature, but we Android engineers always care about how things work under the hood! In this talk, we will understand "Monet", the wallpaper-based dynamic theming system. We will see: 1. What is Monet? 2. Dynamic behavior of system-wide theming 3. Wallpaper color extraction 4. K-means and Celebi quantizers 5. Color extraction strategy 6. Runtime dynamic color updation 7. Dynamic themes with M3 components for Jetpack Compose In this session, we will aim to understand how the Android operating system works to enable dynamic theming (fundamentals of Material You). We will deep dive into AOSP to examine parts of the framework that form Monet and ultimately understand how dynamic system colors work. Join me on this colourful ride!
