I generate a PDF document from user input. This document is then displayed and "signed" by the user.
I need to grab this signature and append it to the document. I'm generating the PDF using Android API and displaying using an external library, but I need a way to re-open the document after signing and modifying it.
It's mandatory to generate the PDF before signing it, so the user can review it.
if the pdf file is saved to your storage after creating and updating it then try to read the file again otherwise you need to store the document first

Faced a number of problems opening documents in a mobile application. We have 2 types of PDF and DOCX documents available.
There are no packages to open Docx for react native.
In order to open a pdf, you need to have the base64 of that document. The back-end does not give back, and in order for the mobile application to create it itself, you need to fasten a heavy package.
Two types of documents can be opened in webview, but only viewing without saving will be available there, and then, this will only work on ios, android immediately starts downloading documents without viewing.
You can use the google.docs service to view documents, but you won't be able to open the document without cookies. Our back-end doesn't let the google.docs robot (for obvious reasons) download the document and display it to us.
I am getting the pdf link from serve. I want to get the users digital signature like shown below,
This signature I can capture and save the bitmap.
Now I want to insert this signature to the pdf which is fetched from the server as shown below.
Once user clicks on done, I shold generate updated pdf file with the signature captured from the user.
I did google search on this and found that with PDFBox it can be achieved.
Can anyone let me know how to achieve this with Pdf box or is there any other alternative solution.
I want to download pdf from my website into my app and that pdf only show in my app only , no other app can access it. What type of logic i need to implement in my Android Code ?
Download your pdf file into internal storage in android phone.According to the android developer site, by default, files saved to the internal storage are private to your application and other applications cannot access them (nor can the user).
Check https://developer.android.com/training/data-storage/files for reference.
I'm currently working on an application that creates a pdf document with a signature of the user.
I managed to construct a new pdf document and fill it with data. My only problem is I don't know how to implement digital signature with pdfbox in an android application.
If you could refer me to sources or share some ideas about that I would appreaciate that!
Hi I am new to use Google App Engine.My requirement is store Large Zip file in a Blob Store and retrieve to my android application when user click a download option It is possible?Can some one Give Tutorial link to how can effectively use android app engine blob store in android application.
Thank's in advance.
The short answer is: yes you can.
First of all you will have to complete the example on how to upload stuff using Google App Engine and then experimenting with the Google Cloud Storage because it will be much cheaper in the long run.
After completing that you will realise that in order to upload, all you'll have to do is to POST multipart data either from Android or using any other method you would like. In that tutorial is also very obvious on how you could download any file back to your Android application.
You could also experiment with one of my examples for uploading files either on Blobstore or on Cloud Storage. In that particular example you are allowed to upload only images and PDF documents, but it's very easy to modify and accepting only ZIP files or whatever else you might want.
Perhaps Google Cloud Storage would be more appropriate.
