The interface element displaying previously accessed applications, implemented in Android Pie, provides a visual representation of the user’s recent activity. This feature allows for quick switching between applications and often includes interactive elements like application previews and quick access to specific actions within those applications. For example, a user can swiftly return to a web browser page or continue composing an email without navigating through the application drawer.
The implementation of this application switching mechanism in Android Pie offered advancements in user experience by promoting efficient multitasking. Benefits included reduced time spent searching for and launching applications, improved workflow, and enhanced device usability. Historically, this feature evolved from simple icon lists to more sophisticated card-based designs that leverage screen real estate to provide more information and functionality.
