App slowdowns and ANRs rarely happen without warning, but traditional crash and performance tools often miss the early signs hidden deep in your app’s architecture. In this hands-on workshop, you’ll learn how to improve performance of your Kotlin and Multiplatform apps using real examples of Android and Compose Multiplatform projects. We will cover: - How misconfigured or heavyweight dependency injection can kill your app’s performance - Why startup times explode due to bad initialization patterns and incorrect thread allocations - How to visualize your Koin dependency graph live for faster debugging - How to spot performance issues under real-world conditions or on specific devices without requiring manual tracing You’ll see how Kotzilla gives you deep, Koin-level visibility into your app’s runtime behavior by combining traditional Kotlin-native crash reporting with architecture-aware performance monitoring. By the end of the workshop, you’ll know how to identify and fix common performance killers before they trigger ANRs or frustrate your users helping you build apps that scale.
