Android Question HTML to PDF - Offline - <page_break_inside: avoid>

[MMORETTI964]

We've a need trying to convert HTML document to PDF.
I know, there is a way to convert HTML to a bitmap (using a webview) and then convert in PDF (like an image).
However we need some more control over PDF created (for example using page_break_inside: avoid). Obviously this is not possible passing through a bitmap.
In some other context (iOs) we use library like BNHTMLPDFKIT who give the ability to transform HTML to "real" pdf (not an image).
As far as you all know, there is a way to get this result from B4A? Even, seems there are no library to wrap from Android world?

Many thanks in advance.

Thank you @Erel

How can I pass html string to pdfDocument?
I can't traduce html to pdf.Canvas.DrawText because html was passed from external sources (it's not hardcoded in app).

Thank you.

Hi @Erel, we've found a way through java.

From this site:
http://www.annalytics.co.uk/android/pdf/2017/04/06/Save-PDF-From-An-Android-WebView/

Intercepting the printing phase of a webview you could write a PDF.

My question is: there is a way to achieve this without build a library (using B4A object and/or reflection)?

Tommorow we will try to put in the library...

You should use Printer.PrintHtml.

 

[MMORETTI964]

We've tried but with PrintHtml open a windows, the user should manually select "PDF", ...
We need to make it programmatically.

So, we will make a library to get the result as a single operation like:
HtmlToPdf("my.html","my.pdf")

Thank you for support.
