that makes the call to the server and it just throws an error. I have the same exact phone this person has and I had him running the exact version I am running, I had not problems calling the server but he still had a problem.

我有他卸载并重新安装好几次，所以我不知道什么会导致这对他的电话，而不是我的吗？

I had him uninstall and reinstall several times so I dont know what would cause this on his phone and not mine?

这是我如何创建XML

this is how i create the XML

private static String CreateCallXML(String sDeviceID, String sEMailAddress, String sVersion) {
    Logging logger = new Logging();
    XmlSerializer serializer = Xml.newSerializer();
    StringWriter writer = new StringWriter();
    try {
        serializer.setOutput(writer);
        serializer.startDocument("UTF-8", true);
        serializer.startTag("", "PostData");
        serializer.startTag("", "RetrieveMsg");
        serializer.attribute("", "ver", sVersion);
        serializer.attribute("", "DevID", sDeviceID);
        serializer.attribute("", "eMailAddress", sEMailAddress);
        logger.append("D", className, "CreateCallXML", "LastIncMsgID:" + Settings.LastIncMsgID);
        logger.append("D", className, "CreateCallXML", "LastDLMsgID: " + Settings.LastDLMsgID);
        serializer.attribute("", "LastIncMsgID", "" + Settings.LastIncMsgID);
        serializer.attribute("", "LastDLMsgID", "" + Settings.LastDLMsgID);
        serializer.endTag("", "RetrieveMsg");
        serializer.endTag("", "PostData");
        serializer.endDocument();
        return writer.toString();
    } catch (Exception e) {
        return null;
    }
}

更新2：

在经历了code看来，用户的电子邮件地址是此问题的用户的电子邮件地址的一个例子是在 abcd3961@gmail.com 如果我使用它抛出异常，当它击中线路拨打电话到服务器。如果我更改邮件地址一个字母它执行调用就好了。

after going through the code it appears that the users email address is the problem an example of the users email address is abcd3961@gmail.com if I use that it throws the exception when it hits the line to make the call to the server. If I change one letter in the email address it executes the call fine.

这是一个KSOAP问题？我怎样才能解决这个问题呢，我不能告诉他改变他的电子邮件地址？

is this a ksoap problem? and how can I get around this as i cannot tell him to change his email address?
