How to attach a text file stored locally in app directory

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_TEX开发者_运维问答T, 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 just run into exactly the same issue (wanting to attach a text file to a Gmail message). If you look in the Android log, the reason for it is:

02-28 21:01:28.434: E/Gmail(19673): file:// attachment paths must point to file:///mnt/sdcard. Ignoring attachment file:///data/data/com.stephendnicholas.gmailattach/cache/Test.txt

As a workaround, you can use a ContentProvider to provide access to files in your application's internal cache so that Gmail can attach them. I've just written up a blog post on how to do it.

Hopefully that's of some help :)

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.
