compile 'com.itextpdf:itextg:5.5.10'

Create directory and file name

class PdfCreator{
public PdfCreator(JSONArray data, Context context) {
        this.data = data;
        this.context = context;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            pdfFolder = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS), "UserPdf");
        } else{
            pdfFolder = new File(Environment.getExternalStorageDirectory(), "UserPdf");
        }
        myFile = new File(pdfFolder.getAbsolutePath() + File.separator + "Cart_Detail.pdf");
    }
 // Write our functions here.....
}

class PdfCreator{

public PdfCreator(JSONArray data, Context context) {

this.data = data;

this.context = context;

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {

pdfFolder = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS), "UserPdf");

} else{

pdfFolder = new File(Environment.getExternalStorageDirectory(), "UserPdf");

}

myFile = new File(pdfFolder.getAbsolutePath() + File.separator + "Cart_Detail.pdf");

}

// Write our functions here.....

}

Write paragraph and Image in our created file.
