title: Display a PDF, allow user to sign it, and then send the signed document to a database
body: <p>I am trying to figure out how to allow users to sign a pdf that will be rendered with the PdfRenderer class in Android. Basically it will display a form that will need to be signed and dated and then submitted. I can handle showing the pdf with the PdfRenderer class but I am not seeing a decent way to allow the user to sign and date that rendered pdf and then save the signed pdf to a database. Is there a way to do this without using a third party? And if not is there a free third party product out there?</p>
