The interface element responsible for managing and switching between recently used applications within the Android Pie operating system allows users to quickly navigate their active tasks. For example, instead of returning to the home screen to relaunch an application, users can invoke this feature to select a desired app from a visual list.
Its introduction in Android Pie represented a significant shift in multitasking interaction, offering an improved experience compared to previous iterations. The revamped design, featuring a horizontal scrolling layout, enhanced usability and streamlined app management, contributing to increased efficiency and faster task completion.
