Bundletool
Bundletool is a command line toolkit for manipulating Android App Bundles and generating optimized APKs tailored to specific device configurations. It serves as a utility for converting bundles into monolithic or split installation files and validating the integrity and size of these packages before publishing.
The tool differentiates itself through the ability to analyze device hardware specifications to extract only the required resource sets, reducing application download sizes. It also provides specialized capabilities for creating and exporting distribution archives for runtime-enabled software kits from pre-compiled project modules.
The project covers broader capabilities including the deployment of compatible installation packages to connected hardware, the export of device specifications, and the verification of digital signatures to ensure code transparency. It also includes mechanisms for estimating compressed download sizes based on target hardware dimensions.
