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?

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.
