Worked on the facebook/buck2-prelude repository to deliver two features focused on optimizing Android build systems. Developed DEX distribution optimization for predex and APK builds, consolidating primary DEX classes across multiple base DEX files and refining library subdivision to improve APK size management and deployment efficiency. Enhanced bootstrap DEX handling to increase build reliability and predictability. In a subsequent feature, enabled bootstrap dexes for instrumentation tests by propagating configuration through android_instrumentation_apk_impl and exposing it in android_rules.bzl. The work leveraged Python and Starlark, emphasizing code refactoring, build system configuration, and DEX optimization to support rapid and reliable Android product delivery.

1 Commits • 1 Features
Jan 1, 2025In Jan 2025, delivered a feature for facebook/buck2-prelude to enable bootstrap dexes for instrumentation tests. This enables passing enable_bootstrap_dexes to multidex calls originating from instrumentation tests, propagates through android_instrumentation_apk_impl, and exposes as a configurable attribute in android_rules.bzl for the android_instrumentation_apk rule. The change is completed with commit 30daa2239d4f2430c41a1e30020e34b891f89237, 'Allow enable_bootstrap_dexes for instrumentation tests'.
