A pre-installed application on Android devices that allows users to view and interact with Portable Document Format files without requiring the installation of a third-party application. For example, upon downloading a PDF document from a website on an Android phone, this application typically opens the file, enabling the user to read its contents.
This built-in functionality provides immediate accessibility and convenience. It removes the barrier of needing to find, download, and configure a separate application simply to view PDF documents. Initially, PDF viewing capabilities were often absent from Android. As the platform matured, the inclusion of this feature became standard, simplifying document handling for a broad user base. The development reduced reliance on external apps and contributed to a smoother user experience.
