Since this post was published, we have released Foxit PDF SDK, the only true multi-platform SDK in the market, available for Windows, Mac, Linux, iOS, Android, UWP and Web. It features a single, consistent core API, as well as a built-in viewer and UI for faster development. Learn more.

Foxit Mobile PDF SDK 4.0 includes great improvements to the UI Extension component of the RDK. With the new version, developers can not only create a full-featured PDF Reader with a few lines of code but also fully configure the UI through the .JSON file included in the package.

About UI configuration

For the first time, in 4.0, the UI extensions component provides a new class called PDFReader. This class provides a full reader with a pre-built UI which includes enable/disable, show/hide customization options.
