How to extract Annotations in PDFTron in Android and save to db?
I'm trying to get all the Annotations eg: INK and save to the db from Android.
I have looked thru the PDFTron examples particularly ElementReaderAdvTest. I can follow where it process Element.e_path and prints out the path.

How do I save each path data and later on I want to convert the path data to svg.

The PDF ISO standard defines an annotation data interchange format called FDF. FDF is a PDF file with no pages, and just annotations and/or form field values.
To just extract the annotations use the following
pdfviewctrl.docLockRead();
FDFDoc fdf = pdfviewctrl.getDoc().fdfExtract(PDFDoc.e_annots_only);
pdfviewctrl.docUnlockRead();
You can then save the FDF file as binary/pdf data in whatever storage you want. You do not have to save the annotated PDF, you can at anytime later on merge back.
doc.fdfMerge(fdf);
You would not go into the ElementReader sample code, that is too low level for what you want, and just FDFMerge and FDFExtract are probably all you need.
