Open MD Files on Android - Markdown Viewer App & API

An MD file contains Markdown, the plain-text markup language John Gruber published in 2004. README files, project documentation, wiki pages and notes are written in Markdown, so developers meet MD files in nearly every code repository. A standard Android text editor opens the file but shows the raw symbols - hash marks, asterisks and brackets - instead of the formatted document.

GroupDocs.Viewer Cloud renders an MD file into formatted output: headings, lists, tables and links appear as they should, delivered as HTML, PDF, JPG or PNG. The Java SDK for Android is added with one Gradle or Maven line and comes with code samples, so adding a Markdown view to an app takes a single API call plus the code to display the result. Page navigation, zoom and thumbnails come with it.

For a single MD file, the free online GroupDocs.Viewer app is enough: upload the document and the formatted version appears in a browser, with nothing to install. The API supports Markdown alongside more than 180 other formats, and the free trial plus the interactive API Explorer make it easy to test a call before writing any code.
