It seems as the intent resolver can't find anything that can handle PDFs. Try installing a PDF viewer on your device.

Try it..

AssetManager assetManager = getAssets();


InputStream in = null;
OutputStream out = null;
File file = new File(getFilesDir(), "pdfname.pdf");
try
{
in = assetManager.open("pdfname.pdf");
out = openFileOutput(file.getName(), Context.MODE_WORLD_READABLE);


copyFile(in, out);
in.close();
in = null;
out.flush();
out.close();
out = null;
} catch (Exception e)
{
Toast.makeText(getApplicationContext(), "no pdf viewer", 2000).show();
finish();
}
try{
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(
Uri.parse("file://" + getFilesDir() + "/pdfname.pdf"),
"application/pdf");


startActivity(intent);
finish();
}
catch (Exception e)
{
Toast.makeText(getApplicationContext(), "no pdf viewer", 2000).show();
finish();
}
}


private void copyFile(InputStream in, OutputStream out) throws IOException
{
byte[] buffer = new byte[1024];
int read;
while ((read = in.read(buffer)) != -1)
{
out.write(buffer, 0, read);
}
}
