我们可以在android中创建PDF文件吗？

  • 我已经尝试了所有谷歌搜索。
  • 还看到了更多的例子。

  • 我试过这个，

    File f=new File("/data/data/com.pdf/test1.pdf");  
Log.d("test", "created");  
Document document = new Document();  
PdfWriter.getInstance(document, new FileOutputStream(f));  
document.open();            
document.addTitle("My first PDF");
document.addSubject("Using iText");
document.addKeywords("Java, PDF, iText");  
document.addAuthor("Lars Vogel");
document.addCreator("Lars Vogel");
Paragraph paragraph = new Paragraph("This is left aligned text with indentation");
paragraph.setAlignment(Element.ALIGN_LEFT);
paragraph.setIndentationLeft(50);
document.add(paragraph);
document.close();
Toast.makeText(this, "Pdf Created", Toast.LENGTH_LONG).show();

但这给出了错误，

我猜想包含 PdfWriter 类的 jar 没有导出到 apk 文件中。

在这里寻找解决方案。
