“文件大到attash”发送电子邮件

Question

尝试发送邮件时显示消息“文件太大而无法附加”。真的存档2429字节。我做错了什么？

 Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.putExtra(Intent.EXTRA_EMAIL,new String[] { "test@test.com" });
emailIntent.putExtra(Intent.EXTRA_SUBJECT,getString(R.string.mail_subject));
emailIntent.putExtra(Intent.EXTRA_TEXT,Html.fromHtml(getString(R.string.mail_body)));
emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("/mnt/sdcard/wc.dbz"));
emailIntent.setType("application/octet-stream");
startActivity(Intent.createChooser(emailIntent,"Send Email"));
