无法接收短信，请帮我更正代码

Question

我不知道是什么问题，但下面的代码没有收到短信，当我在手机内存中看到时，应用程序无效。

有人能纠正这个代码吗
我对此有很多问题，它编译得很好，但当它在真正的手机上时，应用程序会说它无效，诺基亚2630支持MIDP 2.0，所以不是手机问题。

Answer 1

这可能是因为您发送的SMS可能不会在代码中定义的端口上发送

请看这个工作示例。

Answer 2

我找到了，伙计们，谢谢你们的支持，我相信我会带着更多的查询回来，我已经写了一个带有5000端口的接收短信代码的示例，它会在某种程度上帮助别人，在开始之前，右键单击netbeans中的应用程序并选择属性。现在选择应用程序描述符。选择"属性"选项卡，然后选择"添加"按钮。在相应的字段中给出以下内容。名称：SMS端口值：portno现在您已成功注册端口no。

现在再次选择推送注册表选项卡。在相应的字段中给出以下内容。类名：包名.类名发件人ip:*连接字符串：sms://：portno现在你已经成功注册了推送注册表。
