How to Read PDF files in Android?

Read PDF Files from Sdcard in Android

First Create one Android Project in Eclipse after that download PDFViewer.jar file from Internet and then add into project's build path.

After Create one Activity in this Project, Name is Second.java

Second.java

public class Second extends PdfViewerActivity {
   
    @Override
    public void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    }
   
    public int getPreviousPageImageResource() {
    return R.drawable.left_arrow;
    }
   
    public int getNextPageImageResource() {
    return R.drawable.right_arrow;
    }
   
    public int getZoomInImageResource() {
    return R.drawable.zoom_in;
    }
   
    public int getZoomOutImageResource() {
    return R.drawable.zoom_out;
    }
   
    public int getPdfPasswordLayoutResource() {
    return R.layout.pdf_file_password;
    }
   
    public int getPdfPageNumberResource() {
    return R.layout.dialog_pagenumber;
    }
   
    public int getPdfPasswordEditField() {
    return R.id.etPassword;
    }
   
    public int getPdfPasswordOkButton() {
    return R.id.btOK;
    }
   
    public int getPdfPasswordExitButton() {
    return R.id.btExit;
    }
   
    public int getPdfPageNumberEditField() {
    return R.id.pagenum_edit;
    }
}

After that Add below code into your project's main activity and change extends Activity to ListActivity in your java file.

First.java

public class First extends ListActivity {
   
    String[] pdflist;
    File[] imagelist;
    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //setContentView(R.layout.main);
   
    File images = Environment.getExternalStorageDirectory();
    imagelist = images.listFiles(new FilenameFilter() {
    public boolean accept(File dir, String name) {
    return ((name.endsWith(".pdf")));
    }
    });
    pdflist = new String[imagelist.length];
    for (int i = 0; i < imagelist.length; i++) {
    pdflist[i] = imagelist[i].getName();
    }
    this.setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, pdflist));
    }
   
    protected void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);
    String path = imagelist[(int) id].getAbsolutePath();
    openPdfIntent(path);
    }
   
    private void openPdfIntent(String path) {
    try {
    final Intent intent = new Intent(First.this, Second.class);
    intent.putExtra(PdfViewerActivity.EXTRA_PDFFILENAME, path);
    startActivity(intent);
    } catch (Exception e) {
    e.printStackTrace();
    }
    }
}

And Don't Forget to Add Second Activity in Android Manifest file.

Enjoy :--)
