I am making an application which require to open pdf within the android app without using any third party application.also i don't want to view my pdf in webview .For this i use PdfViewer.jar and made a code like below.
java :
public class MainActivity extends ListActivity{
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();
}
}
}}
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;

Any hepl??
Use a proper library in your application handling the pdf logic. When using a library inside your own application no other application is started to view/modify the pdf.
Take a look at https://stackoverflow.com/questions/4665957/pdf-parsing-library-for-android for a summary of available pdf libraries.
Use following code. But PDF viewer application must present on device.
File pdfFile = new File(Environment.getExternalStorageDirectory()+ "/video/"+filePath);
if(pdfFile.exists())
{
Uri path = Uri.fromFile(pdfFile);
Intent pdfIntent = new Intent(Intent.ACTION_VIEW);
pdfIntent.setDataAndType(path, "application/pdf");
pdfIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try
{
startActivity(pdfIntent);
}
catch(ActivityNotFoundException e)
{
Toast.makeText(this, "No Application available to view pdf", Toast.LENGTH_LONG).show();
}
