How to create PDF file using iText or some other library on android?

Solution 1
You can use iText to create PDFs. Use the latest version (5.1.3) and include only the itextpdf-5.1.3.jar in the build path. You can use something like this to accomplish the pdf creation.
Document document = new Document();
file = Environment.getExternalStorageDirectory().getPath() + "/Hello.pdf"
PdfWriter.getInstance(document,new FileOutputStream(file));
document.open();
Paragraph p = new Paragraph("Hello PDF");
document.add(p);
document.close();
Also, don't forget to use the permission to write to external storage in the manifest.xml.

It's Easy,For example
Here the Code in my repository (updated link)
gradle.build
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.madgag:scpkix-jdk15on:1.47.0.1'
compile 'com.itextpdf:itextpdf:5.0.6'

This is my sample coding for creating pdf file with text and image content using Itext library and to store the pdf file in the external Storage location. The only thing is you need to download the itext library and add it into your project.
private void createPdf() {
// TODO Auto-generated method stub
com.itextpdf.text.Document document = new com.itextpdf.text.Document();
try {
String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/vindroid";
File dir = new File(path);
if(!dir.exists())
dir.mkdirs();
Log.d("PDFCreator", "PDF Path: " + path);
File file = new File(dir, "sample.pdf");
FileOutputStream fOut = new FileOutputStream(file);
PdfWriter.getInstance(document, fOut);
//open the document
document.open();
Paragraph p1 = new Paragraph("Sample PDF CREATION USING IText");
Font paraFont= new Font(Font.FontFamily.COURIER);
p1.setAlignment(Paragraph.ALIGN_CENTER);
p1.setFont(paraFont);
//add paragraph to document
document.add(p1);
Paragraph p2 = new Paragraph("This is an example of a simple paragraph");
Font paraFont2= new Font(Font.FontFamily.COURIER,14.0f,0, CMYKColor.GREEN);
p2.setAlignment(Paragraph.ALIGN_CENTER);
p2.setFont(paraFont2);
document.add(p2);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
Bitmap bitmap = BitmapFactory.decodeResource(getBaseContext().getResources(), R.drawable.ic_launcher);
bitmap.compress(Bitmap.CompressFormat.JPEG, 100 , stream);
Image myImg = Image.getInstance(stream.toByteArray());
myImg.setAlignment(Image.MIDDLE);
//add image to document
document.add(myImg);
} catch (DocumentException de) {
Log.e("PDFCreator", "DocumentException:" + de);
} catch (IOException e) {
Log.e("PDFCreator", "ioException:" + e);
}
finally
{
document.close();
}
}

I have created a sample project for creating the pdf file from data using itextpdf/itext7 library
Example project link: https://github.com/rheyansh/RPdfGenerator
Add below dependancy in your application gradle:
implementation 'com.itextpdf:itext7-core:7.1.12'
Important Notes
Add WRITE_EXTERNAL_STORAGE permission in AndroidManifest.xml
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Add File Provider in AndroidManifest.xml
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="com.rheyansh.rpdfgenerator.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths" />
</provider>
Add XML resource folder (see provider_paths.xml in example folder)
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path name="external_files" path="."/>
</paths>
Create RPdfGenerator class

RTransaction model
enum class RTransactionType { plus, minus }
class RTransaction {
var itemName: String = ""
var custName: String = ""
var transType: RTransactionType = RTransactionType.plus
var pricePerUnit: Double = 0.0
var quantity: Int = 0
var totalPrice: Double = 0.0
var transactionDateStr: String = ""
constructor() {
}
}
write below functions in your activity class for creating dummy data
private fun dummyModel(): RPdfGeneratorModel {
val list = dummyTransactions()
val header = "Statement"
val dummy = RPdfGeneratorModel(list, header)
return dummy
}
private fun dummyTransactions(): List<RTransaction> {
val list = arrayListOf<RTransaction>()
val i1 = RTransaction()
i1.custName = "Johan Store"
i1.itemName = "Snacks"
i1.quantity = 4
i1.pricePerUnit = 40.0
i1.totalPrice = i1.quantity * i1.pricePerUnit
i1.transactionDateStr = "10 Sep, 20"
i1.transType = RTransactionType.plus
list.add(i1)
val i2 = RTransaction()
i2.custName = "Alice Store"
i2.itemName = "Chocolate"
i2.quantity = 3
i2.pricePerUnit = 79.0
i2.totalPrice = i2.quantity * i2.pricePerUnit
i2.transactionDateStr = "9 Sep, 20"
i2.transType = RTransactionType.plus
list.add(i2)
val i3 = RTransaction()
i3.custName = "Alexa Mall"
i3.itemName = "Shoes"
i3.quantity = 2
i3.pricePerUnit = 177.0
i3.totalPrice = i3.quantity * i3.pricePerUnit
i3.transactionDateStr = "9 Sep, 20"
i3.transType = RTransactionType.minus
list.add(i3)
val i4 = RTransaction()
i4.custName = "Zainab Baba"
i4.itemName = "Chips"
i4.quantity = 5
i4.pricePerUnit = 140.0
i4.totalPrice = i4.quantity * i4.pricePerUnit
i4.transactionDateStr = "8 Sep, 20"
i4.transType = RTransactionType.plus
list.add(i4)
list.add(i1)
list.add(i2)
list.add(i3)
list.add(i4)
list.add(i1)
list.add(i2)
list.add(i3)
list.add(i4)
return list
}
Now call RPdfGenerator function. Make sure to ask WRITE_EXTERNAL_STORAGE permission before calling. For more details checkout example project
val dummyInfo = dummyModel()
RPdfGenerator.generatePdf(this, dummyInfo)

How to create PDF file using iText or some other library on android?
Is there any tutorial on iText for android?
Thanks
-
Khushwant over 12 yearsHi Tarrant, I want to create an PDF file in android application not in java swing.
-
Khushwant over 12 yearsI am using simple code to create a pdf file in my sd card using iText pdf library, but it is giving following errors. 1. Could not find class 'com.itextpdf.text.pdf.PdfGraphics2D', referenced from method com.itextpdf.text.pdf.PdfContentByte.createGraphics 2. Could not find class 'com.itextpdf.text.pdf.PdfPrinterGraphics2D', referenced from method com.itextpdf.text.pdf.PdfContentByte.createPrinterGraphics 3. ERROR/dalvikvm(309): Could not find class 'org.bouncycastle.cms.CMSEnvelopedData', referenced from method com.itextpdf.text.pdf.PdfReader.readDecryptedDocObj
-
tarrant over 12 yearsI'm assuming you've added the library to your project. I think you may need to run dx (in android sdk) on the jar file since unless you are using Eclipse? Dx is used to turn class files in a non-android jar into dex files so that they can be found/used on the device.
-
Khushwant over 12 yearsYes i have added library to my project & i am using eclipse as IDE.Could you please share version of iText you have used? as iText 5.0.7 is for developing apps on android but its not free.They are charging around $1500 for license. Do you have any other open source pdf library for android.Please share if you know any.
-
tarrant over 12 yearsI used iText 2.0.6. I believe it was open source back then.

GvSharma almost 10 yearsgetting error here.....PdfWriter.getInstance(document,new FileOutputStream(file)); tell me the possible solution -
arTsmarT almost 10 yearsPeople here can help you better if you post the error. And downvoting just because a solution didn't work for you is not the way to go. Please spend some time learning the code of conduct before you post something. Also nobody is going to walk you through a solution without you having tried to debug it at least a little bit on your own.

Michaël Demey over 8 yearsiTextpdf v5.0.6 is listed as the dependency. I have two issues with that. 1. 5.0.6 is insanely old. Stick to newer versions for new applications. 2. You're using iText Java and not iTextG (Android port). The Android port has a few minor modifications. To name a few: exclude the usage of API that isn't in the Android API (java.awt) and prevention of namespace clashing (BouncyCastle). -
David Hackro over 8 yearsyea, I 'm building second example using iTextG ;)
-
Samir about 6 yearsWell. first of all thank you wish I saw your solution few hours before. Second I need to ask itext is not free isnt it ? -
