How to attach a text file stored locally in app directory

Question

I have an Android app that saves a text file directly onto the phone, in the app's install directory. I need to allow the user to create a new email, attaching this saved text file. When I start the intent to send the email, everything shows up in Gmail correctly, but the attachment does not get sent. All of my searches on stack overflow seem to only deal with attaching an image file from the SD card. Below is the code that I used. Please let me know if I have done something incorrectly.

File myFile = new File(getFilesDir() + "/" + "someFile.txt");
FileOutputStream stream = null;

if( file != null )
{
    steam = openFileOutput("someFile.txt", Context.MODE_WORLD_READABLE);
    stream.write(some_data);

    Uri uri = Uri.fromFile(myFile);

    Intent sendIntent = new Intent(Intent.ACTION_SEND);
    sendIntent.setType("text/plain");
    sendIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
    sendIntent.putExtra(Intent.EXTRA_TEXT, email_text);
    sendIntent.putExtra(Intent.EXTRA_STREAM, uri);

    file.close();

    startActivity(Intent.createChooser(sendIntent, "Email:"));
}

I've also tried sendIntent.setType("application/octet-stream"); but that didn't make a difference. I'm at a loss for why the file doesn't attach and get sent.

Any ideas?

I've seen this before and the only way I could solve it was by writing the file to the SD card.

It's worth trying writing to the file to the SD card and attaching it if only to eliminate the files location as the cause of the problem.
