/////
                String FILE = Environment.getExternalStorageDirectory().toString()
                        + "/PDF/" + list.get(position).getTitle()+".pdf";

                // Add Permission into Manifest.xml

                    // Convert the Image to Bitmap
                    Bitmap bitmap = convertImageToBitmap(img.getPath());

                    ByteArrayOutputStream st = new ByteArrayOutputStream();
                    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, st);
                    byte[] byteArray = st.toByteArray();
                    Image im = Image.getInstance(byteArray);
                    document.add(im);

yeah, tried. it is showing cannot resolve method "convertImageToBitmap(?)" and "unhandled exception:java.io.IO.Exception" in the line "Image im = Image.getInstance(byteArray)" – teddy Nov 02 '17 at 08:49
Actually i did this and its working .. Image img =Image.getInstance(picture); img.setAlignment(Image.ALIGN_CENTER | Image.ALIGN_BOTTOM); prPersinalInfo.add(img); and if the list doesnt contains picture, its showing null pointer exception. how to resolve this for not having picture? – teddy Nov 02 '17 at 09:19
How to do that one? – teddy Nov 02 '17 at 10:40
check if the picture path is not null. – Sardar Khan Nov 02 '17 at 10:55
if(picture!=null) { Image img =Image.getInstance(picture); img.setAlignment(Image.ALIGN_CENTER | Image.ALIGN_BOTTOM); prPersinalInfo.add(img); } – Sardar Khan Nov 02 '17 at 11:47
if(!picture.contains("")){Image img =Image.getInstance(picture); img.setAlignment(Image.ALIGN_CENTER | Image.ALIGN_BOTTOM); prPersinalInfo.add(img); } – Sardar Khan Nov 02 '17 at 11:53
these are the checks.Test it and tell me if its working or not.? @teddy. – Sardar Khan Nov 02 '17 at 11:54
