Open Source Groovy Mobile App Development Software

drawable-optimizer is a utility focused on reducing the size of Android app image assets to shrink APK/Bundle footprints. It scans res/drawable* and related resource folders and compresses images using configurable strategies, often achieving meaningful savings without visible quality loss. By running as part of the build, it automates a task that would otherwise require manual tooling passes on individual files. Developers can fine-tune which directories and formats to process and exclude sensitive assets where bit-exactness matters. The result is faster downloads, lower install sizes, and improved memory characteristics on resource-constrained devices. It fits naturally into continuous integration, ensuring optimizations remain consistent over time.

This plugin wires JaCoCo code coverage into Android Gradle projects, generating per-variant coverage reports for unit tests and, when configured, instrumentation tests. It produces HTML and XML outputs that slot neatly into CI pipelines and code quality dashboards. Configuration options let you include or exclude classes (like generated code), merge coverage across flavors and build types, and enforce minimum thresholds to prevent regressions. The plugin integrates cleanly with the Android Gradle Plugin’s task graph, so coverage runs are reproducible across developers and build servers. It helps teams make coverage a first-class metric without hand-crafting custom Gradle tasks for every variant. By lowering setup friction, it encourages frequent measurement and concrete targets for improving test depth.
