H File Viewer - Open C/C++ Header Files on Android

An H file is a header shared by C, C++ and Objective-C projects: it declares the functions, types, macros and constants that other source files include. Headers are where an unfamiliar codebase is easiest to understand, yet they are awkward to read on a phone: Android ships nothing that opens the extension, and a header attached to a bug report stays unread until you reach a desk.

GroupDocs.Viewer Cloud renders an H file into pages an Android app can display at once. A view request answers with HTML, PDF, JPG or PNG, while the Android SDK for Java wraps that exchange in one build dependency. Readers navigate pages, zoom in and open thumbnails, and a long header can be fetched a few pages at a time.

For a single glance at one header, the free online GroupDocs.Viewer app opens the file in any browser, no installation required.

The service is not limited to source code. One account reaches more than 180 formats, from office documents to CAD drawings, and a real header can be tried in the API Explorer during a free trial, before any code is committed.
