Does anyone of you ever generate PDF documents under Android?

It is a task in our current project and I don't find a lot (usable) libraries out there. Our first try was iText but under iText 7.1 they no longer support Android 6.

pdfs are usually created server side using Adobe Content Server.

Adobe Content Server

A poor approach will be to create docs and use pdf convertor libraries to convert doc to pdf

Or, a camscanner like approach , where you join multiple pictures to make a pdf file.

Can you use an old version?

No I didn't.
But I did it successfully under a bridge.

No. Seriously.
It's "Does anyone of you ever generated PDF Documents with Linux?"
^^

Sorry, was a bit tired while asking. ^^

The goal is to generate a PDF out of entered data in an Android App. Our customer wants to have server communication minimized since the people using the app can be in areas without wifi so remotely generating the document is not an option sadly.
