HTML Viewer for Android - Open HTML Files in Your App

An HTML file is a web page saved as text in Hypertext Markup Language. Saved articles, exported email messages, invoices and reports generated by other software all use the format. Android can hand such a file to a browser, but embedding a browser tab inside an application is often impractical, and the layout shifts with every screen size.

GroupDocs.Viewer Cloud renders an HTML file to PDF, JPG or PNG: fixed pages that look identical on every device. Your app gains page navigation, zoom and thumbnails over content that previously reflowed unpredictably, and it can render selected pages of a long document on demand.

Integration uses the Java SDK for Android, pulled in through Gradle or Maven, with code samples for each step. The API accepts HTML among more than 180 formats, so the same viewer code covers PDFs, Office files and images, and the API Explorer lets you test requests in the browser before writing them into the app.

The free online GroupDocs.Viewer app displays HTML files without any setup, and a free trial opens the full API for development.
