Close pdf reader

Ok!
I really want to close the window that hosts my opened pdf . Howto ? So I can go back to my app!
Not only closing the pdf, I want to close the whole dialog/window. "PdfClose()" only closes the opened pdf.

If you want to close the view controller you should take a look at the current demo implementation, for example (in iOS version) you can refer to closeView method of RDPDFViewController class, that calls PDFClose method and removes the view controller.
