This component represents a modular system update element on the Android operating system, encompassing several critical libraries and functionalities. It packages executable code, libraries, and associated data in a self-contained module. An example of its use involves updating system libraries without requiring a full system image flash.
Its importance stems from enabling more frequent and targeted updates to specific system components, thus improving security and performance. Historically, system updates were monolithic and required significant downtime. This approach facilitates gradual improvements and feature additions, ultimately streamlining the update process and enhancing the end-user experience.
