Is there an application that allows you to to fill in dynamic PDF form (XFA forms) on mobile devices (especially Android and iOS)? The form should be available offline (the solution using HTML5 form created with Adobe LifeCycle from the original PDF seems to not be acceptable).
Adobe has said no to supporting XFA in their mobile versions of Acrobat before. I am not aware of anything that will render XFA forms on mobile devices natively, most things convert to HTML 5 for displaying them on mobile devices.
There is a similar question on Stackoverflow about this and it seems no one has found a solution that does this natively.
PDFium would most likely be the best place to start looking.
