The FBReader DjVu plugin enhances the FBReader application by enabling users to read DjVu files seamlessly. This plugin is essential for those who frequently access documents in the DjVu format, as it integrates directly into the existing FBReader interface. To utilize this plugin, users must have FBReader version 2.1 or higher installed on their Android devices.

This plugin operates quietly in the background and does not display as a standalone icon, which means users will access its functionality exclusively within the FBReader app. This design choice streamlines the user experience, allowing for a smooth transition between different file formats without cluttering the application menu. Overall, the FBReader DjVu plugin is a valuable addition for users looking to expand their reading capabilities.
