Export annotations in Android

To extract data from PDF to FDF, then export FDF as XFDF

PDFDoc doc = new PDFDoc(filename);

// Extract annotations to FDF.
// Optionally use e_both to extract both forms and annotations
FDFDoc doc_fields = doc.fdfExtract(PDFDoc.e_annots_only); //PDFDoc.e_forms_only

// Export annotations from FDF to XFDF.

// Optionally write XFDF to a string
String XFDF_string = doc_fields.saveAsXFDF();
Disable annotation auto-save
Annotation updates by default will automatically save to the PDF. Set PdfViewCtrlTabFragment2::setSavingEnabled to false to disable auto-save.
