You can use iText to create PDF files. Use the latest version (5.1.3) and include only the itextpdf-5.1.3.jar path in the build path. You can use something like this to complete the creation of PDF.

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, be sure to use permission to write to external storage in the manifest.xml file.

It is easy, for example.

Here is the code in my reporsitory

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'

activity_main.xml

  <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="com.example.hackro.itext.MainActivity"> <Button android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/btnwrite" android:text="PDF" android:onClick="GeneratePDF" /> </RelativeLayout>

MainActivity.java

 import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.EditText; import android.widget.Toast; import com.itextpdf.text.pdf.BaseFont; import java.io.File; public class MainActivity extends Activity { private static final String LOG_TAG = "GeneratePDF"; private BaseFont bfBold; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } public void GeneratePDF(View view) { // TODO Auto-generated method stub String filename = "david"; String filecontent = "Contenido"; Metodos fop = new Metodos(); if (fop.write(filename, filecontent)) { Toast.makeText(getApplicationContext(), filename + ".pdf created", Toast.LENGTH_SHORT) .show(); } else { Toast.makeText(getApplicationContext(), "I/O error", Toast.LENGTH_SHORT).show(); } } }

Metodos.java

  import android.util.Log; import com.itextpdf.text.BaseColor; import com.itextpdf.text.Document; import com.itextpdf.text.DocumentException; import com.itextpdf.text.Element; import com.itextpdf.text.Font; import com.itextpdf.text.Paragraph; import com.itextpdf.text.Phrase; import com.itextpdf.text.pdf.PdfPCell; import com.itextpdf.text.pdf.PdfPTable; import com.itextpdf.text.pdf.PdfWriter; import java.io.File; import java.io.FileOutputStream; import java.io.IOException; /** * Created by hackro on 24/11/15. */ public class Metodos { public Boolean write(String fname, String fcontent) { try { String fpath = "/sdcard/" + fname + ".pdf"; File file = new File(fpath); if (!file.exists()) { file.createNewFile(); } Font bfBold12 = new Font(Font.FontFamily.TIMES_ROMAN, 12, Font.BOLD, new BaseColor(0, 0, 0)); Font bf12 = new Font(Font.FontFamily.TIMES_ROMAN, 12); Document document = new Document(); PdfWriter.getInstance(document, new FileOutputStream(file.getAbsoluteFile())); document.open(); document.add(new Paragraph("Sigueme en Twitter!")); document.add(new Paragraph("@DavidHackro")); document.close(); return true; } catch (IOException e) { e.printStackTrace(); return false; } catch (DocumentException e) { // TODO Auto-generated catch block e.printStackTrace(); return false; } }}

Result

This is my sample encoding for creating a pdf file with text and image content using the Itext library and for storing a pdf file in an external storage location. The only thing you need is to download the itext library and add it to 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 used iText in a java swing application - it worked well to create some basic PDF files. The code looks something like this:

  @Override public void buildPDF(List<Folder> folders) { Document document = new Document(); String fname = ""; boolean open = false; try { // step 2: // we create a writer that listens to the document // and directs a PDF-stream to a file fname = filename(getName()) + "-" + filename(getDataset().getName()) + ".pdf"; PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(fname)); for (int i = 0; i < folders.size(); i++ ) { // grab the folder LIFolder f = (LIFolder) folders.get(i); if (f == null) continue; open = true; break; } // we have no valid folders if (folders.size() > 0 && !open) { // they selected an empty row javax.swing.JOptionPane.showMessageDialog(null, BUNDLE.getString("report-none-selected"), BUNDLE.getString("report-none-selected-title"), javax.swing.JOptionPane.ERROR_MESSAGE); return; } if (folders.size() == 0) { // get all folders from dataset folders = FolderFinder.findAll(getSession(), getDataset()); } open = false; for (int i = 0; i < folders.size(); i++ ) { // grab the folder LIFolder f = (LIFolder) folders.get(i); if (f == null) continue; if (!open) { open = true; document.open(); } Paragraph p = new Paragraph(BUNDLE.getString("report-heading-summary-main"), getPageHeadingFont()); p.setAlignment("center"); document.add(p); p = new Paragraph(BUNDLE.getString("report-heading-summary-main-sub"), this.pageHeadingFont1); p.setAlignment("center"); document.add(p); blankLine(document); drawLine(writer); /////////////////////////////////////////////////////////////////////////////////////////////////// // Primary Statement Details /////////////////////////////////////////////////////////////////////////////////////////////////// p = new Paragraph("Primary Statement Details", this.pageHeadingFont2); p.setAlignment("center"); document.add(p); blankLine(document); PdfPTable table = new PdfPTable(4); table.addCell(new BorderlessCell(new Paragraph("Dataset:", getFieldHeadingFont()))); BorderlessCell cell = new BorderlessCell(new Paragraph(getDataset().getName(), getTextFont())); cell.setColspan(3); table.addCell(cell); table.addCell(new BorderlessCell(new Paragraph("Data Entry Clerk:", getFieldHeadingFont()))); cell = new BorderlessCell(new Paragraph( (f.getDataEntryClerk() != null ?
