Hi,

I am looking for an application (if possible "free" and accessible via a git repository) allowing the merging of several pdf files.

To extract a page from a pdf file, the choice of this one can be done via the printing application. But I couldn't find a way to select two files and put them in the print spool.

there is:

Thank you in advance for your advice.

I find CamScanner useful not FOSS but available on the Play Store.

@MetropleX Thank you for your sharing.
I looked at the application which could be suitable in terms of functionality but too many trackers (18 referenced) for me.
Even if the app is not FOSS, I would like to install only privacy-friendly apps (much like Magic Earth which is not FOSS but ok for me). There are many pdf manager apps on the app store, but I couldn't find any without ads or trackers.
Thanks again for your suggestion.

    Thanks for your reply @MetropleX. Even if less comfortable, I could effectively isolate the application (and possibly deny network access to it). It would be great if the print spooler could accept a selection of multiple files.
    I will use your solution for now. thanks again
