I have been scanning some documents lately in order to have them with me on my android tablet or smartphone. I share them on DropBox and open them with Adobe reader.
The problem is that most of the PDF's are not opening in the Adobe Reader on Android. I get the following error:
The document cannot be opened because it is corrupted or damaged.
I tried opening it in Moon+ Reader Pro and it does open.
My assumption (based on one scanned document that does open) is that it is a date-related issue. The document that opens is dated correctly (the date it was scanned on) while the others that do not open are dated as in the 1970.
For example the document that opens has the following metadata:
Producer itext-paulo-155 (itextpdf.sf.net-lowagie.com)
Creator pdftk 1.44 - www.pdftk.com

While the documents that do not open:
Creator Simple Scan 3.4.3
Created Thu 01 Jan 1970 01:59:59 AM EET
Is my assumption correct? And how can I fix that so that I can open them on Android and not face this problem again?
