安卓 Intent : Send an email with attachment

Question

我想通过电子邮件发送多个文件。我找到了这个 Android multiple email attachments using Intent但它确实有效，而且我没有收到任何错误消息。它只是不附加文件(我也尝试只发送一个文件，但我得到了相同的结果)。

我是不是监督了什么？你有什么建议吗？

private static void email (Context context, String emailTo, String emailCC, 
    String subject, String emailText, List<String> filePaths)
{
    //need to "send multiple" to get more than one attachment
    final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND_MULTIPLE);
    emailIntent.setType("text/xml");
    emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, 
        new String[]{emailTo});
    emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
    emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, emailText);
    //has to be an ArrayList
    ArrayList<Uri> uris = new ArrayList<Uri>();
    //convert from paths to Android friendly Parcelable Uri's
    for (String file : filePaths)
    {
        File fileIn = new File(file);
      //  Uri u = Uri.fromFile(fileIn);
        Uri u = Uri.fromFile(new File(Environment.getExternalStorageDirectory(), "blabla.xml"));
        Log.v("bla", "filepath: " +u.toString());
        uris.add(u);
        Uri b = Uri.fromFile(new File(Environment.getExternalStorageDirectory(), "blabla.es"));
        uris.add(b);
        Log.v("bla", "filepath: " +b.toString());
    }
    emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
    context.startActivity(emailIntent);
}

这段代码对我有用。 pdfFiles 的类型为 ArrayList<Uri> .

            Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND_MULTIPLE);
            shareIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, getText(R.string.share_subject));
            CharSequence seq = Html.fromHtml(mOCRText.toString());
            shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, seq);
            shareIntent.setType("application/pdf");

            shareIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, pdfFiles);
            startActivity(Intent.createChooser(shareIntent, getText(R.string.share_chooser_title)));
