android - How to open a PDF via Intent from SD card

Question

I'm trying to launch an Intent to open a pdf inside my assets folder in my app. I've read dozens of posts but am still stuck. Apparently I need to copy the pdf to the sd card first then launch an Intent. It still doesn't work.

I think the problem is the Intent launching so I'm simply trying to open a file "example.pdf" that I copied onto the SD card using this code:

Log.w("IR", "TRYING TO RENDER: " + Environment.getExternalStorageDirectory().getAbsolutePath()+"/example.pdf");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(Environment.getExternalStorageDirectory().getAbsolutePath()+"/example.pdf"), "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

try {
    startActivity(intent);
    Log.e("IR", "No exception");
} 
catch (ActivityNotFoundException e) {
    Log.e("IR", "error: " + e.getMessage());
    Toast.makeText(InvestorRelations.this, 
        "No Application Available to View PDF", 
        Toast.LENGTH_SHORT).show();
}

This is my LogCat output.

05-10 10:35:10.950: W/IR(4508): TRYING TO RENDER: /mnt/sdcard/example.pdf
05-10 10:35:10.960: E/IR(4508): No exception

Except when this code is run, I get the following Toast (not produced by my app)

"Not a supported document type"

But I can open the document manually through the PDF viewing app installed. Any help would be hugely appreciated.

Try this code, display pdf file From /sdcard

File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/example.pdf");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
startActivity(intent);
