Java File Viewer - Preview .java Source on Android

A JAVA file holds the source code of a Java class or interface as plain text. Android apps are frequently written in Java, yet the platform itself offers no viewer for the extension: a .java attachment opens in a bare text editor at best, with long lines wrapped and the structure of the code lost.

GroupDocs.Viewer Cloud presents Java source as proper pages instead. The file goes to the REST service, which answers with HTML, PDF, JPG or PNG ready for display on any screen. Users page through the code, zoom into a method and move between thumbnails, and a long file can be fetched in page ranges.

The Android SDK is itself a Java library, pulled in with one Maven or Gradle dependency and demonstrated by code samples, so the integration language matches the files being viewed.

The simplest case needs no code: a JAVA file opens for reading in the free online GroupDocs.Viewer app. Rendering can be confirmed on your own sources during a free trial, with requests issued from the API Explorer, and the same service reaches 180+ further formats.
