Open and view pdf in my application

Question

Using this code:

try {

    URL url = new URL(aurl[0]);
    URLConnection conexion = url.openConnection();
    conexion.connect();

    int lenghtOfFile = conexion.getContentLength();
    Log.d("ANDRO_ASYNC", "Lenght of file: " + lenghtOfFile);

    InputStream input = new BufferedInputStream(url.openStream());
    FileOutputStream fos = openFileOutput("try.pdf", Context.MODE_PRIVATE);
    //PARA DESCARGARLO EN SD//
//  OutputStream output = new FileOutputStream("/sdcard/prueba.pdf");

    byte data[] = new byte[1024];

    long total = 0;

        while ((count = input.read(data)) != -1) {
            total += count;
            publishProgress(""+(int)((total*100)/lenghtOfFile));
            fos.write(data, 0, count);
        }

        fos.flush();
        fos.close();
        input.close();
    } catch (Exception e) {}
    return null;

I keep in the application a PDF of 8 MB size. I've used several codes to try to open it and view it but can not find the way.

Any suggestions?

@DipakKeshariya If possible, I would prefer to open the pdf saved in the same application, if it is not possible, I gigged with open from sdcard — jlopez, Jun 27 '12 at 11:19

Hi Please try below code.

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File("mnt/sdcard/try.pdf")), "application/pdf");
try 
{
    startActivity(intent);
} 
catch (ActivityNotFoundException e) 
{
    // Toast Message
}

Here sFile is SDcard Path.

you can download your "try.pdf" file in sdcard. – Nikhil Jun 27 '12 at 11:05
I'm trying, but it does not open, so the file is not displayed – jlopez Jun 27 '12 at 11:23
If your PDF file is in SDCard then sFile = "mnt/sdcard/try.pdf"; – Nikhil Jun 27 '12 at 11:25
The path I have is: "/sdcard/try.pdf" not is ok? – jlopez Jun 27 '12 at 11:28

the same, in on catch: No Activity found to handle Intent { act=android.intent.action.VIEW dat=file:///mnt/sdcard/try.pdf%20 typ=application/pdf } – jlopez Jun 27 '12 at 12:00
