How do I attach Ormlite database file to email intent in Android

I'm maintaining a legacy Android app that uses OrmLiteSqliteOpenHelper to create a Sqlite database on the device. On the device, I found out this file lives at:

/data/data/[package-name]/databases/mydatabase.db

My app has an "E-mail Support" feature, and I have unfortunately been tasked with attaching this SQLite file to an e-mail Intent for troubleshooting user issues. I'm running into some permission problems. Here is the code I'm using:

public void email(String[] to, String subject) {
    Intent email    = new Intent(Intent.ACTION_SEND);
    email.setType("*/*");
    email.putExtra(android.content.Intent.EXTRA_EMAIL, to);
    email.putExtra(android.content.Intent.EXTRA_SUBJECT, subject );

    File file = new File("/data/data/com.product.companyname/databases/mydatabase.db");
    if( file.exists() )   //this returns false, why?
    {
        if( file.canRead() ) 
        {
            Uri uri = Uri.fromFile(file);
            email.putExtra(Intent.EXTRA_STREAM, uri);
            activity.get().startActivity(Intent.createChooser(email, "Email DB File"));
        }
    }   
}

The file is never attached because file.exists() always returns false, even though in adb I can clearly see that the file exists...

(pardon the redacted product info)

Why is this? If my app created this file, why can't it also read it? If I remove the file.exists() and file.canRead(), I get a toast on the e-mail intent saying "Permission denied for attachment".

Any help is appreciated. Thanks.
