I’d like to integrate a FastPdfKit Reader into my PhoneGap application. That is, the PDF reader should be opened within the PhoneGap app, so that the application-related navigation is still visible.
Where do I best start?
Do you know about any publicly available code that gives an example on how to achieve this?
It sounds like what you are looking for is creating a PhoneGap plugin.
