HTML to PDF Conversion in android app

Question

Is it possible to convert html to pdf using jsPdf in android app ( without using cordova or phone gap) and save the file in device local.?

I tried this and onclick of button i am calling jspdf convertion logic, but pdf is not generating.

In adb log I see below waring on click of button.

Cannot call determinedVisibility() - never saw a connection for the pid: 1153

I am using jspdf library, Filesaver.js.

No, I am still trying to find solution. If I try to load the HTML file in android chrome browser jsPDF is converting and saving pdf file. But it is failing in app ( chromium webview is being used) — Vishwas Rao, Oct 26 '16 at 08:17

This class might help you. But to compile, it must be in package ".../java/android/print/"

Here is a simple code example :

PdfConverter converter = PdfConverter.getInstance();
File file = new File(Environment.getExternalStorageDirectory().toString(), "file.pdf");
String htmlString = "<html><body><p>WHITE (default)</p></body></html>";
converter.convert(getContext(), htmlString, file);
// By now the pdf has been printed in the file.

You completely replaced the Android "copy left" AGPL dependency? That is genius! Thank you! – Ed of the Mountain Feb 15 '18 at 00:08

'LayoutResultCallback()' is not public in 'android.print.PrintDocumentAdapter.LayoutResultCallback'. Cannot be accessed from outside package – behelit Mar 21 '19 at 10:41

Have you placed the class, shared in the answer, in a package with a hierarchy like ".../java/android/print/" ? – Islam Salah Mar 22 '19 at 12:12
@IslamSalah How can we place the class in in a package with a hierarchy like the above? – chaviaras michalis Mar 11 '20 at 14:32
Creating android.print and putting it inside did not work for me – FabioR Oct 20 '20 at 21:32
Have you tried sth like? `my-project-dir/app/src/main/java/android/print/PdfConverter.java` – Islam Salah Oct 30 '20 at 20:24

If you are developing for devices with API level 19+, then you can avoid 3rd party library. Please check the following link:

http://developer.android.com/reference/android/print/pdf/PrintedPdfDocument.html

If you are developing for API level below 19, then check the following links:

If you strictly want to use jsPdf, then try to use jspdf.debug.js.

Cheers!!!

Currently I am using androids Print framework. We want pdf to be generated and saved without any popup. That is not supported in android print framework. – Vishwas Rao Oct 15 '16 at 08:46
I have included jspdf library, jspdf.debug.js. I have a button on HTML page to call pdf conversion, which calls jspdf function. But onclik of button not generating pdf . If I open the HTML file on browser in android device, it tries to generate and download the pdf file ( download blocked saying can download only from HTTP or HTTPS URLs- this is other issue) – Vishwas Rao Oct 15 '16 at 08:50
For examples see https://developer.android.com/training/printing/html-docs – Evgenii Vorobei Sep 03 '20 at 08:43
