how to esign pdf on android

Thanks for the A2A! I never tried to do this on a mobile device. I would think the better way to do it would be to perform the conversion from a desktop application. Still, I wanted to see if it was possible...I downloaded OfficeSuite and tried that as suggested by the other answers, but it seems that the PDF to DOC feature is not available in the free version.I then found a completely free Android app called Able2Doc:Able2Doc PDF to WordAfter you install it, you select the file you want to convert (it can be on your Android device, on Google Drive, wherever), then select Open With - Able2Doc. It then uploads the file to their site, converts it, and downloads it to your device. (On mine, it was stored in /storage/sdcard0/Android/data/com.investintech.com.able2doc/files/userfiles).I don't have MS Office on my PC, so I tried to open the generated doc in OpenOffice, but I got a corrupt doc warning. I was able to open it in Google Docs. It displayed, including images, with just a few minor issues (text alignment, image taking up an entire page for some reason). I would suggest trying it with Microsoft Word to see. It may look perfect there. It was easy to use. Only thing I don't like is uploading it to their site to perform the conversion. Bigger files may take a little while too. Give it a try.

Edit Oct 2014:  http://booksee.org and http://bookzz.org seem to be the two working versions now. Edit July 2014:  Bookfi is gone, but http://bookzz.org seems to be the official clone now. Edit April 2014:  bookza is down, but /, another clone of bookOS/za is up now!  Also,  is another clone.  These just pop up!Edit January 2014:  http://bookza.org is a functional clone of bookos that's live today!Edit December 2013:  Unsurprisingly bookos seems down for good now.  At the moment, it seems http://en.bookos.org/ is unbeatable.  Direct downloads, amazing selection, no ads, etc...  prolly won't stay up for too long though.

UPDATED on December 29th 2014 to reflect changes (since I originally wrote this answer) in the Amazon web site pages layout.The following works for Kindle 3: and for Kindle Paperwhite 3G  both which I own:If you already have PDF's in your computer.  Just email those same PDF files to your Kindle's email address.  If you don't know what is that: go to the Kindle's management page (on Amazon.com), top left menu "Shop by department", then ""Kindle e-readers and e-books", then "Manage your content and devices"once there click "Your devices" tab..Scroll down to the "Personal Document Settings" section and configure the corresponding fields:         "Send-to-Kindle E-Mail Settings"         "Personal Document Archiving"         "Whispernet Delivery Options"you will see an  "e-mail address" column. That is your Kindle email address BUT, there exists another email address, not shown, that has the word "free" added like this:yourKindleUsername@FREE.kindle.com  If you send your PDFs from your computer to your FREE Kindle email address, Amazon will receive the PDF, will "adjust" whatever is required for Kindle viewing of those PDF files and whenever you connect your Kindle to the Internet via WiFi it will deliver the PDFs  to it.Remember, this works for free if you connect via WiFi.  If you do it vía 3G (in case your Kindle has 3G, you may incur in charges, so beware..read the policies on amazon.com regarding this.)I'd recommend that you adjust your "Personal Document Settings" " Whispernet Delivery Options" Maximum charge Limit to $0.00 as to make sure you don't get accidentally charged for this kind of Personal Document transfers to your Kindle if you do something wrong...It seems this also worsk when using Kindle reader applications on your Android phone. The PDF will be sent to your phone's Kindle app whenever you connect to the Internet and sync.Hope this helps. Enjoy your PDFs in your Kindle (or Kindle app).

Reading pdf in android is pretty exhausting. Adobe and other usual readers are just like desktop counterparts, needs scrolling and zooming in and out constantly..Here is the solution .WPS officeWPS Office + PDF - Android Apps on Google Playusing this app YOU CAN READ ANY PDF LIKE AS EPUB!!! Just open the pdf and it will look like this  click on the mobile view and it will transform to..it has a night view option which is so good!!now just scroll and read it just like epub..no zooming in out ... pure reading pleasure!! happy reading!

I've tried this and it works. You can download the PDF on the phone first once its downloaded add it to the DRIVE. It will take some time downloading into the DRIVE. When its finished select the PDF from the DRIVE and press the three dots in the bottom right corner. And there will be an option of ‘add to home screen’ click that and that's it we're done. :)

You can’t. Android App (.Apk) is a whole different thing from PDF. PDF is a file same like word (.docx) where you can read documents. But if you are really in a hurry to make an app you could try appsgeyser and Ionic Creator which creates an app without coding (Drag & Drop) but for Ionic Creator, it does cost money if you want to make it to an apk ( You need to be a Pro User). Instead, in Appsgeyser, you could upload a document and show it (Reading app) in the android app and it’s for free.

I've had great a experience with the Quickoffice PDF viewer which came with my Galaxy Tab 10.1 running Android 3.1. It renders my engineering lecture notes beautifully, including the equations, symbols, and figures. It supports continuous page view, and panning and pinch-to-zoom are fluid. The 10.1" widescreen is a perfect size for reading letter-size pages in portrait mode.
