android - 正文消息出现Android GmailSender错误

当您尝试使用GmailSender类发送电子邮件时，电子邮件到达时没有正文文本，并且已经检查了参数，并且所有参数都只填充了文本。

我的方法

private static Boolean SendMail(ArrayList<Contato> colecao, String localFile, String subject, String body)
{
    Boolean ret = false;

    final GMailSender sender = new GMailSender("[email protected]", "mypass");

    try
    {
        (colecao.size() < 1) return false;
        else
        {
            String recipients = GetRecipients(colecao);

            if(localFile != "")
                sender.addAttachment(localFile,"");//Anexo

            sender.sendMail(subject, body, "[email protected]", recipients);
            Log.d("EMAIL SENDER", "email Enviado com sucesso");
            ret = true;
        }
    }
    catch (Exception e)
    {
        ret = false;
        Log.e("SendMail", e.getMessage(), e);
    }

    return ret;
}

GmailSender类别

    public OutputStream getOutputStream() throws IOException {
        throw new IOException("Not Supported");
    }
}

}

空邮件结果


我该如何解决？我需要发送一些简单的内容，例如带有少量字符的“任何文本”。

最佳答案

修改GmailSender类的sendMail函数，如下所示：

message.setDataHandler(handler);

- message.setContent(_multipart);
+ if(_multipart.getCount() > 0) {
+    BodyPart messageBodyPart = new MimeBodyPart();
+    messageBodyPart.setText(body);
+    _multipart.addBodyPart(messageBodyPart);
+    message.setContent(_multipart);
+}

if (recipients.indexOf(',') > 0)
