APNG Viewer - View Animated PNG Files on Android & Online

An APNG file is an Animated Portable Network Graphic, an extension of PNG that Mozilla proposed in 2004 to add frame-based animation. Unlike GIF it keeps the 24-bit colour and full alpha transparency of PNG, which is why messaging stickers and interface animations often ship in this form. Compatibility is the problem: many tools treat the file as an ordinary PNG and display only its first frame.

GroupDocs.Viewer Cloud gives an Android application a dependable way to inspect APNG content. Its REST API renders the image to PNG, JPG, PDF or HTML, with zoom and thumbnails available, so a media manager or an asset review screen presents the graphic without shipping a decoder of its own. PNG, GIF and over 180 further formats reach the same endpoint.

Sample code accompanies the SDK for Java, which a Maven or Gradle entry installs; test calls can be issued in the API Explorer, and development begins with a free trial. When an APNG file has just arrived and needs a look right now, the free online GroupDocs.Viewer app handles it.
