**Describe the bug** <!-- - I have 150 PDF files, each PDF on a specific topic. I want to create an Android application. - First when you open the application, it shows you 10 divisions, each division containing (15) PDFs, and so on for each division. - I want to upload PDFs from my storage into app. - I also want users to be unable to download PDFs. - I also want the ability to Zoom +/- inside the pdf file because it contains precise details and it is necessary to have the ability to Zoom to view the pdf page. - Can someone explain to me the steps I should follow?
