From Android to QuakeCon: What 90s Game Engines Teach Us About Extreme Optimization

Hear how recent rewrites of the ADB stack and Android Studio debugger directly improve developer workflows. By updating the mDNS implementation and rebuilding Windows USB drivers, you can rely on stable Wi-Fi connections and eliminate system freezing. The updated debugger agent provides accurate stepping and variable inspection for apps written in Kotlin.

Learn how the latest Android Studio AI features can streamline your daily development tasks. While the original agent mode chat was helpful, we rebuilt it with a re-architected experience that supports parallel tool calls and background sub-agents. For instance, you can now have an agent analyze code in the background while you continue working on a different feature. Try out the updated Journeys feature to see how plain text instructions can automatically test your critical user paths.

Discover the origin story of Jetpack Compose and how it changed the way Android developers build applications. We discuss the original challenges of unbundling the UI toolkit from the operating system to deliver faster updates. By adopting Kotlin and a declarative approach, the team reduced the boilerplate necessary to build user interfaces. While earlier systems relied heavily on XML, Jetpack Compose shifts to a code-first model for easier iteration. Listen to the team share their insights on modifiers, performance improvements, and the future of Android design.   Resources: Android is Compose-first → https://goo.gle/compost-first Jetpack Compose overview → https://goo.gle/compose-overview   Subscribe to our YouTube channel → https://goo.gle/AndroidDevs Speakers: Clara Bayarri, Tor Norbye, Chet Haase, Romain Guy

Join hosts Tor and Romain as they sit down with Søren Gjesse, Chris Craik, and Shai Barack. This week, the team dives into R8, the whole-program optimizer that handles the "last mile" of your code before it runs on a device. Learn why implementing R8 is effectively like giving your users a "free hardware upgrade" by making their current devices perform like models that are years newer.

Hosts Tor and Chet are joined by Adarsh Fernando, a Product Manager, and Ray Buse, a Software Engineer, to discuss Journeys for Android Studio. Powered by Gemini's vision and reasoning, Journeys aims to simplify end-to-end test creation and maintenance by converting the natural language you provide to describe the steps and assertions for each test, resulting in actions and evaluations performed directly on your app. Chapters: 0:00 - Intro 1:46 - Journeys: New AI-powered testing approach 3:40 - How Journeys Works with Gemini 4:27 - The natural language advantage 5:49 - Real-world use case: Google Maps 6:53 - Debugging with AI reasoning 8:08 - Why Journeys is important: Bridging the testing gap 9:56 - Journeys and End-to-End Testing 12:18 - Performance and Cached Journeys 24:14 - Android Studio and Firebase integration 25:27 - The development workflow 31:22 - AI for everyone: Beyond end-to-end testing 33:28 - Looking ahead: Feedback and the future  Resources: Journeys for Android Studio → https://goo.gle/4m9YOr3 App Testing (Android) → https://goo.gle/3HVKTqB   Tor on Bluesky → https://goo.gle/3ViCAYS Chet on Bluesky → https://goo.gle/4gzpccM Ardash on Bluesky → https://goo.gle/47JGNw9

To protect users from malware and scams, Android has announced a new layer of security: developer verification. While this is nothing new for Google Play Store apps, Android is extending this to the entire Android ecosystem. Host Tor is joined by Matthew, Patrick, Naheed, and Raz to discuss this latest security update that deters bad actors and creates a safer environment.
