DJVU Viewer for Android - Open DjVu Files in Your App

DjVu is a compressed image format created at AT&T Labs in the 1990s for scanned books, journals and archival documents. Android has no built-in support for it, so an app that receives DjVu scans needs its own rendering path.

GroupDocs.Viewer Cloud supplies that path over a REST API. Every scanned page is rendered server-side into HTML, PDF, JPG or PNG, and the app shows the result in a WebView or an image control. Selected pages can be requested on their own, thumbnails can be generated for a page list, and readers navigate and zoom through long volumes.

An Android SDK for Java handles those REST calls; Maven and Gradle both install it, and the download includes working samples. One subscription reaches 180+ formats, and every call can be tried in the interactive API Explorer first.

A single scan can be read in a browser through GroupDocs.Viewer’s free online app, and no account is required. A free trial lets developers measure the output against their own DjVu archives.
