Enhancing Jetpack Compose app performance

In this video, Tomáš will demonstrate techniques for improving Jetpack Compose app performance through measurement, debugging, and strategic optimization. You will gain insights into the effective use of Macrobenchmarks in Compose to understand startup and runtime performance. Additionally, you'll explore how tracing can provide deeper insights into the behavior of your composables. You will also learn to debug stability issues using the layout inspector and composition debugger. Lastly, we will share techniques to overcome performance challenges, ensuring a smoother app experience.
