Debugging app performance at scale

We all build Android apps — but while they perform flawlessly on some devices, they lag, stutter, or feel janky on others. Animations freeze, scrolling breaks, and often, there’s no clear indication of what went wrong. In this talk, we’ll dive deep into understanding performance in Android apps. You’ll learn how to leverage powerful tools like Android Studio Profiler, System Tracing, and Perfecto to identify and debug performance issues. We’ll then explore how to automate performance testing using Jetpack Macrobenchmark, helping you catch regressions early. Beyond tooling, we’ll discuss how to monitor performance at scale and share best practices to ensure smooth user experiences across a wide range of devices. Throughout the session, we’ll walk through real-world examples, and by the end, you’ll be equipped to make your Android apps truly buttery smooth.
