CompressPng is a Java/Groovy library/plugin aimed at automating the compression of PNG images in an Android / JVM-based build environment. It is intended to help with automatically compressing images (e.g., for Android apps) during the build process, possibly integrating with Gradle or build scripts, thereby reducing the size of PNG assets integrated into apps. Support for usage via Gradle or other JVM build tools (via dependencies). Automatic PNG compression integrated into build workflows. Transparent integration (developers may not need manual steps). Minimal configuration surface (simple plugin / API).

GSN is a middleware (extendible software infrastructure) for rapid deployment and integration of heterogeneous wireless sensor networks. It is tested with Mica2, Mica2Dot, TinyNodes, Wisenode ,Wired & Wireless cameras, several RFID readers,...

Img Optimizer Gradle Plugin is a build-time utility for Android projects that automatically compresses PNG images to reduce APK size. It supports both lossless compression (no quality loss) and near-lossless or more aggressive compression modes, depending on configuration. The plugin runs during the Gradle build cycle, scanning image assets and applying optimizations transparently, which helps minimize the app’s binary footprint without manual image editing. Because it is integrated into the build, it can process only changed images and skip redundant work, improving performance. Its configuration is minimal, making it easy to adopt in existing Android projects. For apps sensitive to download size or memory usage, this plugin offers a practical way to squeeze out extra gains in deployment efficiency.
