linkCreating a new PDF document

To create a new PDF document, call newInstance() and override the OnCreateNewDocumentListener interface. The implementation of onCreateNewDocument(PDFDoc, String) should create a new file with the given title normalized to a ".pdf" extension.



linkAdding pages to an existing document

To add pages to an existing PDF, create a new instance of the add page dialog fragment using newInstance(double, double) and provide the valid page width and page height arguments.These arguments will be used only if the user selects the Custom option in the Page Size dropdown. You also must implement the OnAddNewPagesListener interface and override onAddNewPages(Page[]), in which the implementation should add the provided pages to the document.
