RB File Viewer API for Android - Read Ruby Source Code

An RB file contains Ruby source code. Ruby is the language behind the Rails web framework, build tools and automation scripts, so .rb files appear in code reviews, gists and support tickets every day. An Android app for developers, students or DevOps teams often has to present one clearly on a small screen.

GroupDocs.Viewer Cloud handles the file on the server through a REST API. What comes back is HTML, PDF, JPG or PNG, which your app can place in a WebView or an image view. The script itself is never run, page navigation and zoom are built in, and thumbnails let a reader move directly to a section of a longer file.

The Java SDK for Android is available through Maven and Gradle with working code samples, so a first render request is a short task. Each REST endpoint has an entry in the API Explorer for browser testing, and the free trial covers your own files.

When no app is involved, the free online GroupDocs.Viewer app opens RB files in the browser. The same service handles more than 180 document, image and source code formats.
