Here is the code: (explained in the log statements)

String path = null  ;

File file=new File("/mnt/sdcard/PDFfiles");

File f = new File(file, "MyPDFFILE.pdf");

Log.v("stage 1","store the pdf in sd card");

Document document = new Document(PageSize.A4, 38, 38, 50, 38);  

Log.v("stage 2","Document Created");

PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(path));  

Log.v("Stage 3", "Pdf writer");

document.open();

Log.v("Stage 4", "Document opened");

document.add(new Paragraph("First Paragraph"));

Log.v("Stage 5", "Creating Paragraph");

Image image = Image.getInstance ("/mnt/sdcard/images/3_5_9_0001.jpg");

Log.v("Stage 6", "Image path adding");

image.setAlignment(Image.MIDDLE| Image.TEXTWRAP);

Log.v("Stage 7", "Image Alignments");

image.setBorder(Image.BOX);

image.setBorderWidth(15); 

document.add(image);

Log.v("Stage 8", "Image adding");

document.close();

Log.v("Stage 7", "Document Closed");
