PdfDocument

open class PdfDocument
kotlin.Any
   ↳ android.graphics.pdf.PdfDocument

This class enables generating a PDF document from native Android content. You create a new document and then for every page you want to add you start a page, write content to the page, and finish the page. After you are done with all pages, you write the document to an output stream and close the document. After a document is closed you should not use it anymore. Note that pages are created one by one, i.e. you can have only a single page to which you are writing at any given time. This class is not thread safe.

A typical use of the APIs looks like this: 

// create a new document
  PdfDocument document = new PdfDocument();
 
  // create a page description
  PageInfo pageInfo = new PageInfo.Builder(100, 100, 1).create();
 
  // start a page
  Page page = document.startPage(pageInfo);
 
  // draw something on the page
  View content = getContentView();
  content.draw(page.getCanvas());
 
  // finish the page
  document.finishPage(page);
  . . .
  // add more pages
  . . .
  // write the document content
  document.writeTo(getOutputStream());
 
  // close the document
  document.close();
