Improve Your Android App Performance With Baseline Profiles
Blog post from Stream
Baseline Profiles enhance app performance by pre-compiling source code to bypass interpretation and just-in-time compilation, leading to potential speed improvements of 20-30% from the first launch. By integrating Baseline Profiles, Android Runtime optimizes code pathways through Ahead-of-Time compilation, especially benefiting apps reliant on numerous third-party libraries like Jetpack. The Baseline Profile Gradle plugin in Android Studio facilitates their creation and management, while library authors can also include Baseline Profiles to improve developer experiences. These profiles are embedded in APK/AAB files, where the DEX optimizer uses them to expedite startup and runtime performance through Dex to OAT compilation, AOT compilation, and caching. Users can build custom benchmark scenarios to capture a broader range of user interactions, ensuring comprehensive optimization. Baseline Profiles are manageable via GitHub Actions, allowing for automated updates, and their effectiveness can be measured using tools like Macrobenchmark, demonstrating a significant performance boost in app startup times.
