Create PDF file Extension. Layout to PDF

Hello friends,

this is an extension to Create PDF files with the content of a Layout component (VerticalArrangement, HorizontalArrangement, …).

This extension is based on:
https://developer.android.com/reference/android/graphics/pdf/PdfDocument.html

https://developer.android.com/reference/android/graphics/pdf/PdfDocument.PageInfo.Builder

I have built two versions of this extension: the Simple and the multi-page version.

1.- Create PDF. Simple version.

  • On Screen1 we fill a form. When Click on the “Create Pdf” Button, we pass the data to Screen2 using a TinyDB.

  • Screen2 receives the data as a list and shows a VerticalArrangement1 (yellow) with all the information. With the extension KIO4_PdfS the file is created: (/mnt/sdcard/) “comida.pdf” with the content of VerticalArrangement1.

  • On Screen3 we can “Read” the contents of the file (/mnt/sdcard/) “comida.pdf”, using an Image component.

  • With this version we can only build PDF files with one page.

  • You can download the extension KIO4_PdfS.aix from:

hi @Juan_Antonio is this extension open source?

It’s free.

@Juan_Antonio do i need to give any credits?

Yes of course :slight_smile:

how and where?

I use the About Screen, but somewhere in your app you should have a credits page

could i comment it like in the rules of creative commons 3? and this would be used as a private app by a private entity…
