VSTX Viewer API - Preview Visio Templates on Android

A VSTX drawing template reaches an Android screen as HTML, PDF, JPG or PNG once GroupDocs.Viewer Cloud has answered a single REST request. Rendering runs remotely, so the app stays small while the grids, themes and preset shapes of the template are visible on screen.

VSTX is the XML-based drawing template format introduced with Microsoft Visio 2013. Architects, network engineers and business analysts use these templates as the starting point for new diagrams, because a template fixes the page setup and styling before the first shape is placed. Visio is not available on Android, so a rendered preview is the practical way to inspect one on a phone.

Developers declare the Java SDK as a Gradle dependency, or pull it with Maven, and sample projects are included. Thumbnails, zoom and page-to-page navigation are supported, a protected template opens once its password arrives, and 180 or more formats reach one endpoint. The free browser-based GroupDocs.Viewer app opens a VSTX file as well, and developers can test each request in the API Explorer during a free trial.
