PDF Generate in Android

Hi guys!

Today I am going to share pdf generate in Android tutorial. This tutorial will help you generate your own PDF file in Android. Sometimes, you need to create certain applications where in you want to output the details in the form of a PDF file so that it could printed or used in some other way.

In order to generate PDF we are going to use an external library called Droidtext which is used for PDF creation. It comes with a desktop version and an Android version, the differences between the two can be found over here. For this tutorial, I will be using the Android version.

Add Droidtext .jar file to Android project inside the libs folder and make a java build path.

           PdfWriter.getInstance(doc, fOut);

                 bitmap.compress(Bitmap.CompressFormat.JPEG, 100 , stream);
                 Image myImg = Image.getInstance(stream.toByteArray());
                 myImg.setAlignment(Image.MIDDLE);

                 Phrase footerText = new Phrase("This is an example of a footer");
                 HeaderFooter pdfFooter = new HeaderFooter(footerText, false);
                 doc.setFooter(pdfFooter);
