Android :: Sending Email With Attachment

I never got this to work on a real device, got the email but no attachment, also when installing K9 on a emulator and then sending the email I see the mail in the outbox with a size of 0 bytes:

public static void sendFile(Context context) { File exportDir = new File(Environment.getExternalStorageDirectory(), "mydir"); if (!exportDir.exists()) { exportDir.mkdirs(); } String csvFile = exportDir + "/file.csv"; File file = new File(csvFile); if(file.exists()) { Intent sendIntent = new Intent(Intent.ACTION_SEND); sendIntent.putExtra(Intent.EXTRA_SUBJECT, "CSV file"); sendIntent.setType("text/csv"); //sendIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); //sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + Environment.getExternalStorageDirectory() + "/mydir/file.csv")); sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/ mydir/file.csv")); context.startActivity(Intent.createChooser(sendIntent, "Send CSV file")); } else { Util.displayToast(context, R.string.no_csv_file); } }
