如何在接收来自特定PORT号码的短信时自动调用/唤醒我的应用程序？如何在我的设备上查看此任何演示PORT编号可用于尝试此操作？

只需研究并实施以下代码段，

用于在特定端口上发送短信

public class SendMessage 
{
    public static void execute(final String destination, final String port, final String message) 
    {
        Thread thread = new Thread(new Runnable() 
        {
            public void run() 
            {
                MessageConnection msgConnection;
                try 
                {
                    msgConnection = (MessageConnection)Connector.open("sms://"+destination+":" + port);
                    TextMessage textMessage = (TextMessage)msgConnection.newMessage(
                            MessageConnection.TEXT_MESSAGE);
                    textMessage.setPayloadText(message);
                    msgConnection.send(textMessage);
                    msgConnection.close();
                } 
                catch (IOException e) 
                {
                    e.printStackTrace();
                }
            }
        });

        thread.start();
    }
}

在特定端口上阅读短信

//听取消息的线程

public class ListenSMS extends Thread 
{
    private MessageConnection msgConnection;
    private MessageListener listener;
    private String port;

    public ListenSMS(String port, MessageListener listener) 
    {
        this.port = port;
        this.listener = listener;
    }

    public void run() 
    {
        try 
        {
            msgConnection = (MessageConnection)Connector.open("sms://:" + port);
            msgConnection.setMessageListener(listener);
        } 
        catch (IOException e) 
        {
            e.printStackTrace();
        }
    }
}

//消息到达时

public void notifyIncomingMessage(MessageConnection conn) 
{
    Message message;
    try 
    {
        message = conn.receive();
        if (message instanceof TextMessage) 
        {
                    // here you invoke your application
            TextMessage tMessage = (TextMessage)message;
            formReceiver.append("Message received : "+tMessage.getPayloadText()+"\n");
        } 
        else 
        {
            formReceiver.append("Unknown Message received\n");
        }
    } 
    catch (InterruptedIOException e) 
    {
        e.printStackTrace();
    } 
    catch (IOException e) 
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
