Build PDF file from seperate pdfs links in Ionic


In my app (magazine view app) I have an array of links each composing a PDF page
Each page may have multimedia attached to it (video, gallery)

I need to be able to view them offline

Im wondering about the following

  • Can i compose the all the downloaded files into one big one in the
    local file system?
  • In Android , what is considered best practice to view the actual pdf?
  • Any way to add multimedia to existing pdf?
