The phrase indicates the process of restricting a user to a single application on an Android device. This functionality is not a native feature directly labeled as such within the Android operating system, but rather can be achieved through various methods, including using screen pinning or third-party applications. For instance, a parent might want to limit a child to a specific educational app, or a business might dedicate a tablet to a single kiosk application.
Implementing this type of access control enhances device security and usability in specific contexts. It prevents unauthorized access to other apps or settings, minimizing the risk of unintended changes or exposure to inappropriate content. Historically, managing access on Android devices has required developer intervention, but user-friendly methods have evolved to streamline the process for non-technical individuals.
