CS File Viewer for Android - Read Source Code on a Phone

Developers keep classes, interfaces and business logic in CS files, which hold plain text and often number in the thousands inside one repository. Reading a single file during a review away from the workstation is a normal need, yet Android registers no application for the extension, so there is no way to open it on the device.

GroupDocs.Viewer Cloud renders CS files remotely and returns PDF, PNG, JPG or HTML pages that an Android app can present. Line structure and monospaced characters are kept, and paging with zoom makes even a long file readable on a small display.

The Android SDK for Java arrives from Maven, brings worked examples, and needs one entry in the build file. Selected pages of a large file can be requested alone, password-protected documents are accepted, and this API reaches over 180 other formats, from Markdown notes to full specifications.

A quick look needs no project at all, because the free GroupDocs.Viewer app opens a CS file in the browser. Every request can be tested in the API Explorer, while a first integration fits within a free trial.
